You know..I have a couple of BTC in various wallets that I have lost the private key things too. It never used to bother me as it was like 50 quid or something at the time. Now I find out that its actually 20k? Great
I also somehow had 1.5 BTC nicked from an online wallet a few years back. Which pissed me off as that was a few hundred at the time, but again, this is now 15k worth
**** BTC
