Who here is using them? Yet another exchange has suffered a security breach resulting in lost bitcoins for wallet holders: http://www.coindesk.com/czech-bitcoin-exchange-bitcash-cz-hacked-4000-user-wallets-emptied/ I've printed paper wallets before from www.bitaddress.org - looks like there's a number of online paper wallet generators now, as well as more secure offline scripts that can be downloaded. Any reported instances of bitcoin losses originating from an online generated paper wallet?
