Would it be possible for CoinBase to have some kind of FDIC like insurance? It seems like that's the biggest problems with bitcoins these days is that there's no safe place to store them.
Paper wallets can get lost or stolen, A lot of online wallets get hacked, and DIY encryption doesn't seem like a great way to go either, especially for grandma.
I'd happily pay a fee to coinbase in exchange for some kind of insurance against them being hacked.
