Coinbase is the one exchange that's looked like a legitimate business. Between insider trading and execution problems, it's pretty alarming. (Who am I kidding? Clearly this is actually good for Bitcoin somehow.) Worth noting Coinbase has two kinds of systems risk. There's the technical risk of writing and running code correctly. And there's also the financial risk of them making the market in Bitcoin. Both of those tasks have gotten a whole lot harder recently as Bitcoin transactions have gotten slower and more expensive. Turns out building a global currency with a global 7 transaction / second limit may not be a good idea.
