CoinMetro was supposed to be this huge exchange that would revolutionize crypto. They wanted to fix the problems other exchanges like Binance and Coinbase Pro were having. Unfortunately, it doesn't look like this project will ever come to fruition. Right now they appear to be stuck in deep water without a paddle! However, competing exchange Nauticus launched and has so far been successful in doing what they set out to do. It's unfortunate that the great "crypto drought" destroyed a lot of these projects that could have been worth something.

https://coinmetro.com/Coinmetro had good intentions but just failed to keep sentiment up or deliver what they promised. Sad but it happens. Nauticus is still kicking and I hope they continue to do so. I will support them until they make unforgivable mistakes; but so far so good.
I'm glad I avoided the whole CoinMetro project. They seemed like they were on track for success, but you know how that goes with ICO's that never launch.
