It's impossible to see how much money you've wasted, even if you export your transactions in CSV, since the fiat wallet transactions are labeled the same as a normal purchase, and you can't set a limit price for buying and selling which ultimately screws you into losing money. For example i messed up and sold 10 avax and when i went to buy back within a minute i could only buy 9.5, which represents a loss of $40.. Great!
