Also what has me confused is say I get usdt in Tron network. When you want to send usdt in tron network to someone... do you need to make two separate transactions? One is sending the Tron fee first... and then send the usdt in the tron network? Do you make each payment one after another to the usdt tron address you are sending to?
For dex youll definitely need tron network coins to send your usdt since it will be the one used for the transaction, while on cex you dont need the coin of tron itself since they will deduct the fee on your transacted usdt. As far as I know if using tron is free on some centralized market but not sure if this is still free cause its been a while since Ive used tron.
