Initially, bitcoin mining took place only by means of a computer. After cryptocurrencies gained popularity and significantly increased in price, more convenient and effective methods were developed. These methods are based on video cards. After that, processors were created, and then ASICs. Already in 2013, developers surprised users with a new device that took the form of a USB drive.
An ASIC miner is a small device that requires a lot of electricity. For comparison, it is worth saying that the computer consumes much less. In such a miner, as a rule, there are two or more boards with a large number of processors. This device makes a lot of noise and heats up very quickly, but it is very efficient from an economic point of view.

Bitcoin belongs to such coins. The CoinWarz site provides users with a list of coins, and also allows you to calculate the profitability level with the help of a special calculator.
What are the advantages of a USB miner? First of all, it should be said that this device does not require a separate power supply or network connection. The connection takes place through any PC or laptop. Also, this device does not heat up so much, so cooling is not required. It cannot be said that this type of miner is absolutely silent. The convenience of storing such a miner is at the highest level, because its size is small. Advantages include ease of transportation and relatively low cost.
As for the minuses, you should be prepared for the fact that the hashing speed will not please you with high indicators, because many devices have an outdated ASIC chip. To speed up the operation of such a miner, it will be necessary to spend much more money.
It cannot be said that a similar type of miner will be able to bring a large profit. From an economic point of view, the USB miner does not justify itself in any way. Only if the value of the cryptocurrency increases sharply, the user will be able to count on a profit. But even with such a schedule, it will be possible to earn much more only at the expense of ASIC.
Then why should you buy a USB miner? This type of miner is more suitable for training. It will allow you to acquire skills and experience, but at the same time investment in equipment will not be needed. Such a device is an excellent assistant in overclocking microcircuits. It is worth noting that some people collect such miners so as not to forget where bitcoins started.
