I have usdt, want to swap it to tron but I don't have Tron to make swap.
If there is such exchange available, let me know.
You have usdt in tron network than there is no way to swap without paying trx fee. trx withdrawing fee is very low from centralized exchange. you have just to pay one trx for withdrawal and also minimum withdraw limit is very low only 2 trx. You want to withdraw usdt from tron network to other networks or just want to swap from usdt to trx ans hold?
Tron is famous for feeless/low fee transactions but it's not the case in reality.
Tron was charging very low fee, This is true. I am using Tron network for many years but in two years they increased their fee approximately 2$ trx for one transaction of usdt which is second high fee charger after Ethereum. I have not used for some months and not aware now how much fee Tron charging for one transaction
