I've lost more in my own local wallets due to losing both of the USB flash drives that contained the keys (as ridiculous as it sounds, I think my girlfriend's cat stole one of them).

Realistically, I've come to think cryptocurrency just isn't for me; it's too damned easy to lose. I also forgot my passphrase for some other BTC (I think I remember it, but it doesn't work, so, there those went). It's not huge sums; 1 BTC here (which was only worth about $300 when I "lost" it), a half BTC there, but the only BTC I still have access to is the half of one I have at Coinbase.

I may yet find one of those flash drives, or figure out what my passphrase actually is for the others. But, what I have found for sure is that BTC is too hard to keep safe (mostly from myself).
