I stumpled on bitcoin back in the autumn of 2012 through a random google search: At the time I was thinking of investing my surplus student loan (a few hundred usd worth) and thought about possible industries that I should invest in. I had this notion that the internet revolution wasn't over yet but rather one industry at a time was still being revolutionzed from the less conservative to more conservative. I tried to think of industries that were ultra conservative and hadn't really been digitized yet. Banking was the obvious answer (actually thought of car industry first) and after some random googling I stumpled on Bitcoin through pure luck.

Bought Bitcoin with everything I had to spare at 9usd IIRC. Couldn't believe my luck when Bitcoin started mooning soon thereafter and, of course, sold most like a fool. I hadn't really thought through my investment strategy in the case if I actually was right. You could say I took a big investment risk but hadn't properly planned on how to take profit out of it which was idiotic. In the end, I still have about 25% my original Bitcoin. And, no, I'm not rich as I only had very little money to invest back then. But I did pay back my student loan with profits which was nice.
