If you were attempting to mine Bitcoin with a PowerBook I can confidently say you mined zero Bitcoin

Edit: I thought he was talking about 2012 but yeah in 2010 CPU mining was still a thing

Wasn't the difficulty like 6 orders of magnitude easier back then?

Okay maybe in 2010 you could use a CPU but even by 2012 it was entirely dominated by GPUs and I think even dedicated hardware was coming out around that time or soon after

ehhh you could CPU mine in the early months IIRC. The issue was that 50BTC wasn't even worth a penny back then lol
