why Blockchain.info is so popular and why it's not recommended to keep your coins online UNLESS that online wallet happens to be Blockchain.info. In fact, there is a popular saying that "if you don't have the private keys, then you don't own any bitcoins".
This is one of the worst pieces of advice I've ever heard. blockchain.info is probably one of the worst online wallets, even though you own the keys.
From their failed ARG generators, the accounts being compromised despite having 2FA on, their insecure way of emailing wallet backups, you should consider moving your coins if you use this piece of garbage.
