1. Coinbase or Circle 2. There really aren't any! Not for the average user, not right now. Adoption was only ever going to start with niche use cases, like international remittances, some B2B applications, darknet sites, etc. I think most people will start using Bitcoin without realizing it, as is the premise with 21inc. and many others. I think OpenBazaar will see some success, too. There's lots of time for this to work out, and speculators will drive the price for a long time. 3. A fiat blockchain is just expensive and inefficient fiat. Why do you need a public ledger when you're already placing all your trust on a bank or government? Just keep the private ledger that's cheap and trivial to implement. I think many people have this notion of thinking about Bitcoin like currency, but that's really not right. Bitcoin is a trustless network, and all of it's power and innovation stems from that. Introducing a trusted party to that just destroys all of that.
