Got interested in 2011 because of a podcast http://omegataupodcast.net/59-bitcoin-a-digital-decentralized-currency/ with Gavin Andresen (read the comments under the podcast description :-)).
Because of that, had my first node running on a windows 2000 machine in 2011 for a few days I believe but didn't fully understand what this was all about really and it was hard to get bitcoin easily anyway at that time and there was not much material available to learn.
So I removed the node from my machine and moved on with my life only to come back 10 years later in November 2021 to buy BTC at the ATH: I bought BTC at the price I deserve it, me stupid fuck. Now I DCAed every month since then and a got my break even price "down" lol to $38k.
