1. Downloaded the original bitcoin client and started solo mining. Looked up that with my hash rate it would take a month or two to mine a block (reward was 50btc at the time) so I just closed the client and forgot about bitcoin for a while. Didn't know about mining pools until 2013. But at least I did get 0.05 BTC from that one site that gave them away for free somewhere around 2011-2012 😁
