Today, we will be looking into how a USB ASIC miner work and if it is still profitable for mining in 2020.

The Origin of the USB ASIC Miner

USB ASIC MinerWhile at first Bitcoin could only be mined with CPU power, in 2013, a new type of mining hardware emerged the ASIC miner (Application Specific Integrated Circuit).

ASICs are special hardware designed only for mining cryptocurrencies that are based on the Proof of Work protocol, such as Bitcoin, Bitcoin Cash, Ethereum, etc.

As ASIC rigs are quite expensive to buy and own, a lighter version of this device appeared on the market: USB ASIC miners.

How Do USB ASIC Miners Work?

Bitcoin mining is the process of validating new transactions and releasing new coins into circulation.

A USB ASIC miner connects to the computer’s USB port and, with the appropriate software, executes the computing process required to do the mining. To get a better hashing output, multiple ASIC miners can be connected to the same PC.

As a computer usually has anywhere from 2 to 4 USB ports, you can use the ports to connect as…
