... how many coins could be mined in a day on a standard home PC?
I saw a guy being interviewed on a news channel the other day about Bitcoin. Assuming he's telling the truth, he said he stumbled across Bitcoin in the very early days when it could easily be mined with a basic computer. He said he was easily mining up to 50 coins a day but, given these were very early days for crypto, he didn't really know what he was mining (as in what they could be used for, potential value etc) so he placed no importance on it whatsoever. So much so, he didn't retain the keys for many of his earlier coins
He said he got back into it a few years back and is now a lot more careful about the crypto he has. The guy could very likely have been a multi-millionaire by now. Not sure if he's mining these days (doubt it) or buying/trading.
I find it surreal in a way that you can be sitting today deciding 'do I buy 1 coin for $50k?' whilst only a decade ago you could have been mining dozens of them, essentially for free, on your home PC! Yeah I know that's all with the benefit of hindsight, however it makes me smile nevertheless.
I wish I'd stumbled across it 10 years ago!
