I was into Bitcoin in 2011-2012 and I got paid in bitcoin to help someone with fixing some bug on a forum. It was more than 10 BTC. I spent some of it on buying some video game I don't even remember and the rest... Well I was an idiot and I formatted the drive with the wallet and I didn't write down any recovery key (in fact I don't think seed phrases even existed back then, or at least weren't widely used).

I didn't get back into bitcoin until the last few years ago
