What does it look like when a person is extremely ruthless? Take a look at this overseas big shot! In 2011, he mined with a regular computer worth only $700. At that time, he could reliably mine one Bitcoin per day. This computer was used until it broke down and was shut down, accumulating a total of 792 BTC. To this day, he still holds onto one that he hasn't sold. Sharp vision is fundamental, but the true key to making big money is having patience and the ability to hold on.
