BSC's recent rise in mining, let's take a look. Yesterday, I set up a 4090 with a cost price around 2800U. Now, a 4090 mining machine can mine 40 $BTE a day. Based on the current coin price, that's 200U a day. It will break even in 14 days. If the coin price returns to 10U, it will break even in 7 days, and the rest is passive income!
