Should I enable or disable "Tax crypto fees in transfers"?
Quick Answer
Enable this option if your country treats crypto transfer fees as capital gains realizations.
Detailed Answer
When sending crypto between your own wallets it is often required that you pay a transfer fee. In many countries this transfer fee is seen as you spending your crypto. Hence, it should be treated the same way as realizing a profit or loss. In this case you want to ensure that this setting is enabled so that Divly correctly calculates the realized gains on the transfer fees.
Divly will have set this setting automatically based on your country.
