if you buy USDT for UAH and then BTC for UAH and sell BTC for USDT, you will be at a loss due to the commission for buying and selling within 0.05 - 0.20%

Hello. Please tell me if I buy UAH for USDT, then BTC for UAH, and sell BTC for USDT and do this many times. Will this be considered a violation? Could I be blocked for such actions? After all, this is triangular arbitrage.
