Back in late 2009 early 2010 a friend who owed me $20 gave me 20 bitcoins instead. I was not up on crypto then, and I think he said they were worth like 10 cents a piece and said he guaranteed that they would be worth $20 in a year. I said sure whatever man it’s just $20. Fast forward a year and I completely forgot about them sitting in a file on my PC. I got a new PC and junked the old one. A few years later it came to me what I had done. It’s a bummer every time I think about it lol. Still not as bad as the guy who accidentally threw away 150 million in bitcoin but having 1.3 million dollars would be nice.
