The origin of bitcoin mining was USB miners which was performed on Computers and Laptops but as the value grew everyday the Developers started more expensive and earn able methods using GPU’s by which earning increase as hash rates increased.
In fact the first bitcoin mining device was originally a USB stick which appeared in 2013 names as Block Erupter Saphire.
Mining with USB Miners
The current bitcoin GPU miners are heavily equipped Box size Devices which consume more electricity are Hot and Noisy but have better Hash-rate and earn more.
While the original idea was USB miners or stick miners which were not really like modern day miners at all so these were able to get plugged into a Laptop or a CPU but were completely non profitable and did not have that result at all.
These miners were able to mine Bitcoin and all SHA-256 coins, including Bitcoin Cash,Name coin,Maza Coin,Peer Coin, Tiger Coin,Joule Coin,Unbreakable,e-Mark , A-Coin,Terra Coin,Crown,Unobtanium.
SHA-256 coins are those crypto currencies that are based on POW (Proof of Work) algorithm.

- They are fairly good in terms of Heat as modern miners need external cooling expensive in order to stay efficient in terms of output.
- Less sound makers as compared to GPU.
- No Space required and are portable.
- Cheapest with regards to GPU miners and are as low as 12 to 13 dollars second hand.
- Multiple USB miners can be attached to a single computer.
Disadvantages of USB Miners
- The only drawbacks are that these miners are out dated and have low or no profit as compared to modern day miners and can be used for educational purpose for new comers or as memorandum of Bitcoin.
- However to match a good hash-rate you have to spend to much for getting results of a single GPU miner.
