According to this site right now there are over 50 coins with a market cap greater than 100 million USD. Even my favorite dogecoin, literally a joke, is "valued" at 164 million. It is my favorite because I used to play some online poker in dogecoin, and it was fun playing 10k/20k NL holdem. Way cooler than playing .0000001/.0000002 NL bitcoin Holdem.

I think anyone with half a brain knows what would happen to these market caps if people tried to cash out. I wish there was some way to know the true $ total of actual economic activity being conducted in crypto. I know after using it once for a bullion sale I never touched bitcoin again, after waiting 18 hours for the transaction to confirm.
Having said all that, I'm watching for the next true technological advance.
