Commissions. They are invisible, but they are always nearby. You open a deal - pay. You withdraw funds - pay. Even just transferring tokens - and pay again. At first, it seems like small things. Then you look at the transaction history - and realize how much you've lost 'little by little'.

If you are trading actively, enable commission display in orders. It's a simple setting, but it makes things much clearer. You gain an understanding: is it worth opening a deal with such a spread and fee? Especially on small volumes.

Sometimes, you choose an exchange only for convenience - and miss that its fees are one and a half to two times higher than the market. Or you don’t check which networks are available for withdrawal and accidentally pay $20 for a transaction that could have been done for $0.3 through another network.

Commissions won’t wipe out your deposit in a day. But they will definitely wear you down. And the worst part is that you quickly get used to them and stop noticing. But you should.
