I mean, I've given them the ability to withdraw money from my bank account so merely trading on CoinBase requires me to believe they won't do that or anything like that. The fact of the matter is that I don't trust CoinBase, but I know that our interests are somewhat aligned. If they damage their reputation by stealing my BitCoins or my cash they lose money because people don't trust them any more. They are backed by people I consider to be reputable and if CoinBase does something shady all of their reputations will suffer.
