Best Cryptocurrency Trading Apps for Android

Cryptocurrencies are gradually occupying the minds of users and are striving to take a place in the global financial system. At one time, they experienced a real boom, which was associated with a sharp increase in the value of some currencies, especially Bitcoin. Now activity has decreased slightly, but public interest and belief that this is the currency of the future still remains. We'll see what comes of it, but cryptocurrencies have already become so accessible that they can be traded literally from a smartphone. In this article we present a selection of applications that allow you to do this. Many consider them as a serious investment tool, since you can make good money on the Bitcoin exchange rate. Well, maybe that's true.

There are many cryptocurrencies, the main thing is to choose the right one.

Blockfolio

Blockfolio is a rate control program that supports more than 8,000 types of cryptocurrencies. The application shows prices in digital and graphical form, making analysis easier and more efficient.

Available options: 1. Control the cost of more than 8,000 virtual coins online. 2. Current news on future cryptocurrency rates. 3. Current exchange rate and market situation analysis. 4. Notifying the user when the price reaches a certain level.

Blockfolio developers paid attention to the security of the program. There is a PIN code to protect your personal account, it is possible to transfer or restore information, and the function of hiding the balance works. Support operates around the clock with the possibility of communication via Telegram or e-mail. The seriousness of intentions is confirmed by the presence of pages on many social networks.

The high user rating (4.8) confirms the quality of the application. People note the convenience of buying/selling, the absence of unnecessary functions and the convenient display of data. The number of installations exceeds 1,000,000, which is further proof of the effectiveness of Blockfolio.

Cryptocurrency wallets for Android

Before installing the wallet, make sure that it is not a fake. Otherwise, you risk losing your money.

To eliminate unnecessary risks, go to the office. bitcoin.org website page and open the section with recommended wallets:

https://bitcoin.org/ru/wallets/mobile/android/

***

A cryptocurrency wallet typically guarantees:

  • Full control over your account. No one can check how much money you have and freeze it if desired.
  • At the same time, no special trust in the reliability of the transfer is required - all transactions are irreversible.
  • As a rule, cryptocurrency wallets are open source, which allows us to hope for their reliability

***

Although, in this case, all three advantages have a downside:

  • You must take care of the safety of funds yourself (protect your device from hackers and make backup copies of wallets)
  • If you transferred money by mistake or the receiving party did not fulfill the terms of the transaction, you will not be able to return anything and will not be able to complain anywhere.
  • Open source code allows it to be studied not only by honest developers, but also by malicious hackers for vulnerabilities. Therefore, do not keep too much money in the so-called. "hot" wallets.

***

When choosing a wallet, you should pay attention to the following aspects:

  • Developer Reputation
  • Security (open or closed code, method of storing keys and confirming transactions)
  • Anonymity (the need for identity verification, as well as encryption and IP hiding mechanisms)
  • Functionality and user-friendliness of the interface
  • Transaction cost (is there an additional fee for developers)

***

Bitcoin Wallet

We have to admit that this is the simplest application for sending and receiving Bitcoins that you can imagine. Nothing extra - just you and bitcoins.

This is not only the first mobile wallet from the list presented on the bitcoin.org website, but also, probably, the very first bitcoin wallet on Android, the development of which began back in 2010 by the famous programmer Andreas Schilbach.

***

During the Bitcoin tour of Europe, Bitnovosti had the opportunity to talk with programmer Andreas Schildbach, developer of the popular Android wallet Bitcoin Wallet for Android. The conversation took place on March 3, 2016 at a Bitcoin meetup in the Berlin cafe Room77.

***

Synchronization is extremely fast, because... only a small portion of recent transactions is needed.

Security is implemented as simply as the wallet itself - a password for the application and a backup copy. If you lose your device with backup, you lose your bitcoins.

Therefore, it is simply necessary to have reliable tools at hand for encrypting and synchronizing data, in our case backups. And no clouds!

By default, the wallet uses an advanced version of Bitcoin addresses - bech32, which is part of the SegWit technology. In particular, this innovation significantly speeds up the transfer of bitcoins between similar addresses (and makes them cheaper). You can read about SegWit and its benefits here.

By the way, the presence of SegWit support is a rule of good manners for any self-respecting Bitcoin wallet (if we are talking about “real” Bitcoins).

The commission level is set manually (three modes), although there is no way to set a specific amount. Although, usually, the recommended value suits the user quite well.

Additional features include the ability to connect only to a trusted node (and you can only trust yourself) and offline payments via bluetooth (synchronization occurs later when the device is connected to the network). You can connect to certain nodes not only directly, but also through Tor.

At this point, in principle, there is nothing more to say about this wallet, and you can move on to more interesting and advanced options.

***

If you wish, you can practice “on cats,” or rather on test bitcoins. They are almost no different from the real ones, with the exception of the name.

***

Electrum Wallet

This is already a more remarkable thing from an extremely popular brand, known for its reliable and functional desktop applications for storing cryptocurrencies. Although, one is enough to work with bitcoins. It’s great that the desktop client is available in a portable version, which allows you to use it directly from a protected flash drive. But, this is material for another article.

***

The Electrum family of wallets are lightweight clients that do not download the blockchain to your device, which requires them to connect to remote nodes. True, in the settings you can choose which node to connect to, including, it could be your node.

Like the desktop version, the mobile application uses a number of addresses to receive and send coins, which significantly increases the confidentiality of transfers.

Also, Electrum differs from the previous wallet by the presence of a seed phrase for recovery from any device. True, in this case, it is recommended to take care of the safe storage of the twelve most important words in your life, for example, engrave them on metal and hide them away from prying eyes.

Another interesting feature, in addition to the default support for SegWit, is the built-in interface for making payments on the Lightning network.

Lightning Network support added to Electrum wallet

Although, other special wallets will be presented here for Lightning.

Finally, it is worth noting the convenience of creating new wallets for use in the Electrum mobile client and a more flexible approach to managing commissions. Overall, the application leaves a pleasant impression and can be safely recommended for everyday use.

But for more complex cases, where maximum confidentiality is required, more functional and no less well-known things have been created.

Samourai Wallet

“We are privacy activists who have dedicated our lives to developing software that Silicon Valley will never build, that regulators will never approve, that venture capitalists will never invest in. We create software that Bitcoin deserves, and we are proud to be open source!”

Yes, after this it is impossible to ignore this project. Here, even the most experienced geek will certainly secretly wipe away a stingy tear.

It should immediately be noted that to obtain a full-fledged wallet, you need to download it not from Google Play, but from the official website of the developers:

https://samouraiwallet.com/download

https://github.com/Samourai-Wallet

***

Today, Samourai Wallet, launched back in 2015, is rightfully considered the most feature-rich and advanced Bitcoin wallet available on Android OS.

In order to describe in detail all the functions and features of the wallet, or rather, the whole set of software from the Samourai family, you will need to make a separate material, so only a general, brief description of the mobile client will be presented here.

Samourai Wallet features:

  • Full Segwit support for fast and low-cost transactions
  • You control your own private keys, which are not transferred to third-party servers
  • Dynamic evaluation and custom commission settings
  • STONEWALL technology to enhance the privacy of your transactions
  • Ricochet technology against transaction tracking
  • Send and receive private payments using PayNym (BIP47)
  • Deterministic input/output sorting for greater anonymity (BIP69)
  • Increasing the commission for a sent transaction using Replace By Fee (RBF) and Child Pays for Parent (CPFP) technologies
  • Routing outgoing transactions through a trusted node
  • Addresses are not reused
  • Standardized export/import function. The backup is compatible with any other wallet based on BIP44/BIP49/BIP84
  • Hidden mode. To access the wallet you need to dial a secret code on the call panel
  • Remote SMS commands to remove a wallet from a lost or stolen device
  • Built-in local Block Explorer
  • Seed phrase support
  • Full client-side encryption
  • Connection via VPN or Tor
  • Full offline mode

It’s worth looking at Whirlpool’s functions in a little more detail. Whirlpool is a completely decentralized analogue of a regular cryptocurrency mixer (toggle switch), which works as part of the technology for anonymizing transactions - CoinJoin. The function mathematically separates the inputs of senders from the outputs of recipients, thereby complicating the process of tracking transactions.

Mechanics of anonymous coins

Thus, the Whirlpool framework is a modular implementation of CoinJoin, developed using the ZeroLink protocol, or rather its modified fork.

At first, Whirlpool was only available in Dojo, a full-featured desktop wallet that is a full-fledged node equipped with advanced features and a user-friendly interface. The solution turned out to be extremely popular, and with the addition of a toggle switch function to the mobile version of Samourai, it caused a threefold increase in the volume of anonymous transactions in a few months.

***

Sentinel

Sentinel is the so-called A “watcher wallet” whose sole purpose is to track balances and transactions, as well as create new addresses for cold hierarchical deterministic wallets.

According to the developers, Sentinel does not store user IDs or private keys. To track an address, you simply need to scan the XPUB (extended public key). You can install the application from the Google Play store or from the developers' website.

***

Exodus

Well, no one can get enough of Bitcoin alone! For those who need to work with several cryptocurrencies at once, the Exodus application offers not only wallets for dozens of different coins, but also the ability to exchange them among themselves. It's scary to think, but Exodus can store more than 100 cryptocurrencies and derivative tokens.

More details here: https://www.exodus.io/status/

A multi-currency wallet does not require registration or any personal data at all. Coins are freely convertible among themselves with a minimum commission (to miners). Exodus itself does not charge anything.

True, like all glamorous wallets, it has strange features. For example, the seed phrase for recovery is available only after depositing the first funds to any wallet address. Although, the PIN code can be set immediately.

+closed source, which does not add value to it. The commission is not set manually - it does not suit a promising blockchainer to squeeze pennies.

Private keys are also stored on the client side, which is definitely great. The blockchain is not loaded - all sacraments take place on third-party servers. Although, for a mobile client this is normal.

In general, Exodus is a beautiful and convenient wallet, without serious shortcomings and claims to revolution.

BLW: Bitcoin Lightning Wallet

Now comes the turn of innovation: a two-in-one application that allows you to perform transactions on both the main Bitcoin network and the Lightning network.

In the best traditions of the technological underground, private keys do not leave your device, which provides some guarantees of the safety of funds.

It is worth recalling that Lightning Network technology allows instant (theoretically) payments in Bitcoin, which is implemented through a second layer (add-on) on top of the main network. You can read about how it works here.

***

During installation, a new wallet and seed phrase are created for recovery. Don't forget to write it down.

In order to start using the Lightning Network, you first need to top up your balance in bitcoins, and then open a payment channel with one of the nodes in the network.

True, the kind developer has already taken care of this, and one channel (his own) is already open by default:

Moreover, this is not an easy channel, but a hosted channel with a reserve of 0.1 BTC, which allows you to immediately issue Lightning Nerwork invoices to other users (without replenishing the balance on your part). But this is a feature of this particular wallet.

The payment link is one-time and short-lived.

***

If you decide to open channels yourself with other nodes, you will need a little theoretical knowledge.

It is important to know: you cannot receive or spend more than the amount you sent to open the channel. Moreover, in order to receive any amount within the channel width (invested amount), you must first spend the same amount of money.

Example: you need to get $100 through the Lightning Network. You take your $110 in bitcoins, top up your Lightning wallet balance, then open a payment channel with one of the nodes (the list is in the wallet), wait, wait again, then if the node is happy to see you, a channel for $110 opens.

Do not disconnect until the channel is finally open - a change in its status will indicate this!

Each node has its own minimum for opening (maintaining a node is expensive). If $110 is not enough for him, he has the right to have nothing in common with you. These nodes are equal users just like you. There is no bank or responsible persons here.

Now you must make room to receive $100 - to do this, withdraw $100 back (through the exchange office) or spend it, there will be $10 left and space for the new $100.

Thus, it becomes clear that using the Lightning Network requires some investment. You just need to understand that if you just need to get $100, use the main Bitcoin network for this, and if you need to pay $2 for a cup of coffee every day with a minimum commission, then use the above scheme with Lightning. If you find a place to pay for coffee via the Lightning Network. I personally prefer to drink coffee from a beer mug at home.

Important to know: receiving payments is only possible if your wallet is online. And second: your partner has the right to close the channel at any time. And if you are offline, your deposit may go to a dishonest node (although, as a rule, the funds are returned back to your Bitcoin address). Therefore, connect only to known nodes.

True, here too the developer of Bitcoin Lightning Wallet took care of user safety. By default, the wallet already has a special service enabled, the so-called. a “watchtower” that monitors your channels for violations by partners for a nominal fee.

And remember that the payment may not go through - in this case, the money will also be returned back after some time.

Additionally, it is once again recommended to carefully read everything about the features of this technology.

Crypto App

Crypto App is created for people who are interested in the world of cryptocurrencies. With its help, you can monitor the exchange rate, receive prompt price notifications, read news and receive other relevant information. Crypto App will be useful to existing investors and people who are just planning to start making money on cryptocurrencies.

The Crypto App cryptocurrency application combines many functions, which allows you to limit yourself to its installation and abandon other software. The main feature is the absence of usage fees.

Crypto App user rating is 4.6. People note an interesting interface, a large amount of useful information and convenience. There are also dissatisfied users who note incorrect display of rates and periodic problems with loading charts.

NeoNeonMiner

NeoNeonMiner is another miner application, but it supports many algorithms. Unlike its first opponent, this program is not a client of a cryptocurrency mining pool. Developer information is also embedded here.

The NeoNeonMiner interface is very simple - there are only three tabs: the mining itself, settings and the necessary information. It is worth noting that antivirus programs mark the service as potentially dangerous. During testing, a banner appeared that was impossible to close.

There are about 18 algorithms for mining. However, here too the speed let us down: only 2.66 kH/s - this is not enough to obtain any benefit. And even if you sit in NeoNeonMiner around the clock, there will be practically no benefit from this, only losses: the mobile device will be overloaded and the battery will heat up!

Bitcoin Map

The Bitcoin Map application provides accurate information about the location of merchants that accept Bitcoin. With its help, you can quickly determine where to spend cryptocurrency to buy certain things. Each store has an address, telephone number or website. To clarify the information, you can dial the number of the outlet and get additional information.


Screenshot of the Bitcoin Map application

Peculiarities:

  1. Filtering stores by name.
  2. Updates to the list of retail outlets based on your location.

Bitcoin Map uses data from openstreetmap.com to determine store addresses and Google Maps to display locations. During installation, the program asks for access to phone calls and photos.

The average user score is low (3.8), but this is due to glitches in past updates. After creating the new version, many errors have been fixed. The disadvantage is a small number of stores in the CIS countries.

Cex.io

Cex.io is another reputable exchange site that offers reliable apps for iOS and Android smartphones. Cex.io does not support as many currencies as Binance does, but it does offer improved features for the altcoins that are on its list. You can purchase crypto coins in the app using debit or credit cards.

Types of programs and why they are needed

Most often, trading bots, or “automated trading systems,” appear in the field of view of new and experienced traders. Bots do all or almost all the work instead of the user, and can even conclude transactions on his behalf. There is a category of bots that only advise the trader to perform certain steps - they are called advisors.

Trading bots have become widespread, and today about 80-90% of transactions on the cryptocurrency market are carried out by such programs. Some of the most famous names are 3commas, RevenueBOT, Cryptorg. Read more in our article: Trading bots for crypto exchanges - review of desktop and web versions.

A trading terminal is another important type of software used by traders. Essentially, this is a “trader’s workplace.” The trading terminal provides access to various exchanges, providing all their functionality. Without leaving the terminal program, the user can place orders on one or more exchanges, specify stop losses and take profits, and also use additional analysis tools provided by the terminal developers.

Trading terminals can be divided into:

  • manual;
  • automatic;
  • multiterminals.

Automatic terminals can conduct some operations instead of the user, for example, copying the positions of the most successful traders. Multiterminals include programs that allow you to conduct transactions on different exchanges and even markets from one account.

Some of the programs are available only for PCs, while others can be used via a browser. Among the most common are MetaTrader and QUIK terminals.

An equally important category is programs for tracking market movements and monitoring your own portfolio. Comparing your transactions, assessing the value of your portfolio in various cryptocurrencies, statistics, warnings, and a market news feed are just some of the functions of such programs.

Blockfolio and Cointop are some of them.

Ecoinia

The Ecoinia cryptocurrency application will be useful to users who are seriously interested in mining and investing in cryptocurrencies. This is a powerful platform that allows you to monitor the exchange rate of virtual coins and stay on top of the latest news.

Ecoinia is a free cryptocurrency app that allows you to understand how blockchain and decentralization work. Earnings are calculated automatically, which allows you not to bother using a calculator.

The average rating based on user opinions is 4.3. People like the convenience, the ability to build an investment portfolio, and the availability of alerts when there are farm failures. The downsides are the long loading time for cryptocurrency charts and the lack of mining capabilities.

Bots

There are also automated bots in the form of applications and online services for cryptocurrency trading.

RevenueBOT

Cloud platform for trading automation. After selecting and connecting a crypto exchange (12 platforms are available) and selecting a trading pair, you can choose an algorithm or set up your own strategy by placing specific orders.

  • finding new friends with similar interests;
  • creating chats;
  • conducting personal correspondence;
  • exchange of audio and photos.

The application is suitable for people who love communication and want to keep up with the news.

Conclusions: mobile apps are not effective

We took only three applications as an example, but in reality there are many more. But in general, mobile programs will not bring profit. Yes, the applications really work, but the results are insignificant, it's like running in place. And the applications themselves do not inspire much trust: constantly pop-up banners and signals from antiviruses are not signs of good software.

But if there is a race to the death, and the count is on pennies, it is worth remembering that smartphones are quickly overloaded from the work of such services. Often devices cannot cope with overheating on their own, which causes a number of problems. No, no mobile mining is worth possible breakdowns of smartphones!

Based on all of the above, the conclusion is quite obvious. Today, mining is a matter for professionals who are ready to invest in new technologies. There is fierce competition in the field of cryptocurrency mining, where Android smartphones are just mere pawns against the backdrop of specialized hardware.

Binance

The Binance program is an addition to the famous cryptocurrency exchange that allows you to trade cryptocurrency from your phone. Using the software, you can buy and sell virtual coins through the application, make exchanges and solve other problems.


Binance app screenshot

Possibilities:

  1. Quick purchase and sale of virtual coins.
  2. Accurate charts and trading tools.
  3. High level of profile security.
  4. 24/7 user support.

The money received can be withdrawn at any time, which guarantees the availability of the funds earned. The average user rating is 4.4. People note the ease of working with digital assets, the quality of the application and ease of use. Negative reviews are rare.

Web services
