you pay a commission. Your balance should have enough funds for a transaction.
Ok, thank you

Is there anything I can check my cashback from unless I don't have enough GAZ for transaction?
You can calculate it using the formula.
CASHBACK is 5% of all deposits to the brokers accounts that traders made in cryptocurrencies. You can use the following formula to calculate your Cashback:
CASHBACK = LHC*[(In-Out)*0,05]/E , where
LHC is the number of tokens you hold
(IN Out) is the amount deposited to the brokers accounts minus all the withdrawals made from it
E the total amount of emitted tokens = 101 788 634
For the first period, our total proceedings (IN-OUT) in crypto has amounted to a relatively low amount of 87000 USD.
Ok, for my case it's 0.8547.
