A buddy paid me back lunch money he borrowed in 2014, but in Bitcoin instead of USD. In 2016 I started taking Kratom and in 2017 when my $20 was now worth $300 I used it to buy lots of Kratom. Some sites took Bitcoin directly back then. I had to stop taking Kratom because of how crazy addicted I got. In spring 2022 I finally was able to break the habit.
