However, it did feel a bit disingenuous when I find that CoinChimp actually has a bitcoin wallet where they store your coins in cold storage, not unlike Coinbase. And where they, unlike BTC-E, aren't anonymous, they have an address to mail money to, the founders are known. In other words, not complying with legal responsibilities of being a money transmitter while also managing your bitcoins is something I'd be MUCH more worried about as a user, as this is the type of thing Liberty Reserve tried to do. Transmit money, report nothing, manage people's funds yet not be anonymous or untraceable. That means you're in trouble before long, which means your customers are too.
We don't have an address to mail money to. I don't know where you saw that, but it was definitely NOT on CoinChimp.
Of course CoinChimp offers a Bitcoin wallet. We deposit coins to your CoinChimp wallet when you buy them. They are stored by default in cold storage NOT on a live wallet on the server, therefore they are not vulnerable to hackers. You can withdraw your coins to a third-party wallet or an electrum wallet simply by clicking Withdraw BTC, which we encourage people to do.
Unlike CoinBase, we don't request ID or verification from our customers.
