Coinbase are shady as hell. They openly admitted that they hand out customers' details to third parties for "processing", and that some of these third parties share and sell that data with even more third parties, all without their users' knowledge and consent. They hand over customers' data to the government. They formed a partnership with a company who produce and sell privacy invading software to dictatorships and human rights abusers. I wouldn't trust them with a single satoshi, let alone all my personal details.
