I have notice that the Crypto Universe Selection does not change often. Even if the exchange has added new symbols, they have not been available to trade on the platform. I tried some through trail and error. An example UNI is availabe even though it is not listed on the documentation page. Of course I wouldn't expect it dynamic updates to the documentation. But if we could add more of the top liquid coins- ADA, DOT, MKR, etc.... and with BTC currency pair?
