What are free bitcoin mining websites


So you want to dive into the world of crypto currencies, mine yourself and have obtained the appropriate hardware? Then all you need is the right software tools to lay the foundation for your digital wealth. We'll show you the five best tools (in our opinion) to do cryptomining.


The CGMiner is already six years old. The tool is operated via a simple command line interface that could put off many users who are used to a more modern user interface.

CGMiner is written in the C programming language, which means that the cryptomining tool runs on almost all operating systems. In addition, CGMiner runs with special mining hardware as well as with all possible GPUs. The program only needs the login data for the mining pool of your choice and then automatically detects which hardware is available for mining purposes. The software is extremely adaptable and offers an abundance of setting options - however, the Windows version is often stubborn when it comes to installation.

  1. Ethereum
    Another cryptocurrency based on the blockchain principle. Provides a platform for programmable smart contracts. The "ethers" are seen by fans as the legitimate successors of the Bitcoins (see also the picture above).
  2. Cryptlet
    Service developed by Microsoft for the Azure cloud, with the help of which users can enter external data into a blockchain without destroying its security and integrity. As individualized middleware, cryptlets can also be developed by Azure users themselves - in any programming language - and are intended to bridge the gap from the blockchain to new business services in the cloud.
  3. Cryptocurrency
    Digital money, without coins and bills. With the help of cryptography, a distributed, secure and decentralized payment system is built. Does not need banks, but computing power and technical aids such as the blockchain.
  4. Blockchain
    A blockchain is a decentralized database that keeps a constantly growing list of transaction data records. The database is expanded linearly in chronological order, comparable to a chain, to which new elements are constantly being added at the lower end (hence the term "blockchain"). When a block is complete, the next is created. Each block contains a checksum of the previous block.

    The technical model of the blockchain was developed in the context of the cryptocurrency Bitcoin - as a web-based, decentralized, public accounting system for all Bitcoin transactions that have ever been made.
  5. Bitcoin Core
    The open source software validates the entire blockchain and was approved at the beginning of 2009 by a certain 3220391 "target =" _ blank ">" Satoshi Nakamoto " published under the name" Bitcoin ". Bitcoin Core was initially programmed in C ++ primarily for Windows systems. Porting to GNU / Linux followed a little later. Because the developers fell out, there are now some derivatives of Bitcoin software, including Bitcoin XT, Bitcoin Unlimited or Bitcoin Classic.
  6. BigchainDB
    The "scalable blockchain database" can manage up to a million write operations per second, store petabytes of data and still have a latency of less than a second - all of this managed in a decentralized manner and with the highest data integrity. The technical basis is blockchain technology.
  7. Distributed ledger
    Financial term for "distributed account management". Bitcoin is a completely new technical approach to distribute information about certain mappings. There is no longer a classic account that is managed centrally at a bank, but "account management" is based on a network of communicating systems.
  8. Smart contract
    A computer protocol that can map or check contracts or provide technical support for the negotiation of a contract. Could replace the written contract in the future.
  9. R3CEV
    The startup R3 CEV is building the blockchain-based "Global Fabric for Finance". The largest blockchain in the world is to be developed with around 50 financial partners - a first test run with eleven major banks, including Barclays, Credit Suisse, HSBC, UBS and UniCredit, has already been successfully completed. R3CEV has entered into a strategic partnership with Microsoft to develop blockchain infrastructure and technology in the Azure cloud.
  10. Ripple
    An open source protocol for a payment network - currently still in development. P2P payment method and foreign exchange market in one, based on the crypto currency "XRP". However, Ripple users are not limited to this one currency, but can use any currency - for example, euros, dollars or yen.


Bitminter is one of the oldest, most reliable and most sophisticated cryptominer ever. Bitminter works equally well with both ASICs (application-specific integrated circuit) and GPUs. The graphically appealing design makes working with the mining software a pleasure. The hashrate is displayed in MH / s (millions of hashes per second) and to start mining cryptocurrency, the start button is pressed like in a car.

Bitminter also offers access to various statistics that you can use to monitor the progress of your mining operations in no time at all. The user interface also includes a text console that keeps you informed about hardware and software updates.

The big disadvantage of the Bitminter Cryptominer: It is designed exclusively for use in the associated mining pool. If you want to use the tool, there is no way around registering with Bitminter. As a result, you are then also forced to accept their terms and conditions when it comes to dividing the cryptomining income.


The BFGMiner tool is based on the design of the CGMiner, but is only intended for use with ASIC mining hardware and not for mining cryptocurrency using a graphics card. As it should be for special software, BFGMiner has a lot of settings and features with which the software can be adapted almost completely to your individual cryptocurrency needs (if you also know what you are doing).

With the help of the BFGMiner, for example, the operating temperature of connected devices can be monitored and several mining pools can be accessed at the same time. The Cryptominer prevents connections to inaccessible pools from the outset, which increases mining efficiency.

The interface of the cryptomining software is not necessarily all the rage - but it does the job. Commendable: This tool for mining Bitcoin, Ethereum and Co. also supports the setting up of hotkeys - in case you have to act really quickly.


MultiMiner offers a graphical overlay for BFGMiner. What is that supposed to mean? First and foremost, the setting options for advanced users are also more accessible for beginners.

The tool for mining cryptocurrency has a setup wizard on board to help you connect to a mining pool. Once this has been done, MultiMiner automatically searches for and finds connected devices and provides information on these in a clear table. At this point you can also inquire about your daily "exploited" profit - depending on which crypto currency you generate and which hardware is used for it.

You can also configure MultiMiner to automatically mine the cryptocurrency that promises the greatest profit at the moment. Or the one that is easiest to mine.


EasyMiner is also a graphic front-end interface - but for the Cryptominer CGMiner and CPUminer. This tool also makes it extremely easy to start mining cryptocurrency: it automatically creates a Litecoin paper wallet and starts mining.

The EasyMiner dashboard is attractively designed and presents all available information and options in a simple and understandable way.

Before you start cryptomining

A common problem with cryptocurrency mining software is potential conflicts with antivirus solutions. These can not only occur during installation, but possibly already when downloading a Cryptominer.

The reason for this is the increasing popularity of "cryptojacking" among criminal hackers: Here, cryptomining software is smuggled onto a user's computer, where the tool then generates crypto currencies without the knowledge of the user. If you run into problems with security solutions when using Cryptominern, all you have to do is add the program in question to your whitelist.
