Guess how many private keys were lost during that LA fire?

That fire in LA was one of my biggest security concern for my keys also = my home getting burned down when I'm away.

Can't store your private keys on your phone. It's a piece of paper people often keep it where it's safest (their homes). Aside from breaking ins and theft, fire hazard is the biggest risk. Wouldn't wish it on anybody to go for a trip and then come back to a burned down house where possibly a piece of paper inside is worth more than the house and land. Well, unless you have one of these metallic private keys but I think not everyone has them. Also it's easier said than done, but finding a piece of tiny square amidst a burned down house with tons of ash, debris, wood, etc. is harder than you might think.

People are reporting house values but we still don't know what the crypto values are and I'm sure they must have kept some there.

What other security back up would you use in case of such an event?
