TikTok users use USB mini mining machines to mine Bitcoin at Starbucks.

TikTok user Itami Abada released a video today in which he used Starbucks’ free electricity to run a mini Bitcoin mining platform worth $875. Abada explained: “This is one of the easiest miners to build and run, because you only need a computer or laptop.” It is powered by USB, nothing more. So everyone can become a miner and become a part of the crypto world mining pool. "His mini mining machine generates 0.0002478 bitcoins every month, minus 5% of the mining pool fee, which is equivalent to 9.35 US dollars at today's price.
