Overall, the app looks nice and is pretty easy to understand. Will you be adding portfolios in the future?
One comment I have for you-- when you do a search for a coin and mark it as a favorite, it is not obvious how to get back to the main screen. Usually I get back there by hitting Cancel which seems a little strange but it works. Also, what is the difference between USDT and USD?
Yes we are going to add portfolio feature in next week's new version.
Yes. That's how to back to the main screen. USDT is the token operated by Tether, which is 1:1 to USD.
