NiceHash mining payments seem to be incorrectly reported. The amount should be net fees so that it is reported correctly for taxes, but it is in fact not net but gross. This results in a steadily increasing remaining balance in the nicehash wallet.
For example if I am paid 1 BTC in a mining payment and there was a fee of 0.1 BTC it should be shown as +0.9 BTC to the wallet, but instead 1 BTC is getting added to the wallet balance.
Additionally fees aren’t reported at all before 3/1/2021
