Really slick website! One feature I've wanted is to be able to put the price I got my crypto for and see the relative gain or loss from that rather than the previous day or week.
One thing I'm still trying to figure out for example is whether to let people enter the total amount they paid for all of their crypto, or let them enter the amounts they paid for each transaction. I'd prefer the first, as adding transactions would make the app less simple. But is is still useful that way?
