There's no possibility to have a current profit\loss overview on your portfolio or at crypto level. The issue with posting of DAI accrued interest is solved. If you want to send crypto, their system does not automatically deduct the network\coinbase fee, you have to do the math (not a constant error). Their fees structure is terrible - 1 euro flat fee for every transaction, even for a 2.5 euro sale of marginal crypto that I had in my portfolio.
