Just looking at the stock perf. They have high trading fees and still lose quite a bit every quarter. They need to figure out their business plan when trading activity is lower, or figure out some way to drive trading activity.
I think they have an excellent chance of being the last one standing. Unless we learn that they have also been operating a scam. If all they do is run a reliable exchange and don't get hacked, as other exchanges fall they'll probably get more business.
But I think if public interest wanes, and crypto sort of becomes this amway for nerds thing, then they'll probably flounder unless they prune back their costs significantly.
I don't. Crypto traders will never learn. They'll continue to see that coinbase has high fees, low volume, and a limited set of coins and they'll continue to use scammy unregulated exchanges. When one dies they'll just switch to the next one. The majority of crypto volume will never be on a centralized US regulated exchange.
