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/I don't think CoinMetro have failed totally in their exchange business,maybe they are waiting for the general crypto market improvement to mint their XCM tokens to be added to the exchange for trading.
it's been almost a year since the project was released, and I see no very significant increase in their projects. maybe a lot of investors when ico has gone and sold now
