Under his leadership, his company achieved remarkable success, capturing a substantial portion of the Bitcoin mining market by 2013.

The value of the shares in his company soared, reflecting the booming interest and investment in the Bitcoin sector at the time. However, the pressure and expectations mounted as rapidly as his fame and fortune.
