It's not so much about profit as it is about regulatory concerns. The relationship between Coinbase and the SEC is a very tricky one. The SEC most likely views Coinbase as a means to develop a new financial surveillance network. To make things even worse, there are ways to rid yourself of these little breadcrumb trails that automatically become attached to you after a BTC purchase. To me it seems like the SEC and the Fed are completely stumped on how to handle Bitcoin. Never forget that organizations like these and many others think of money like this: "If we can't own the vast majority of the money, then no one can" 🤷♂️
