Trying to understand the initial service that Coinbase provided. It seems like this was allowing people to buy Bitcoin from a USD bank account. (https://web.archive.org/web/20130424175129/http://blog.coinbase.com/post/34357253898/you-can-now-buy-and-sell-bitcoin-by-connecting-any-u-s)
What was the easiest way to buy Bitcoin before this? Why did Coinbase implement purchases from bank accounts before credit cards?
What regulatory licenses did Coinbase need to acquire to provide this service? Did they need money transmitter licenses in all states? Given that it only took a few months to launch this service, I'm guessing the regulatory reqs were minimal.
Personally, I got crypto back then by renting nodes on cloud services and CPU mining. The alternatives generally involved either ACH/wires, meeting someone locally, or trusting a non-US credit card provider with your $ and payment information. At the time, I was happy to take a 5-10% haircut to skip most of the risk.
