I want to get some usdt on either of these networks.  Reason is because I want to send a few tiny payments.  By tiny payments...  i mean like 5 dollars and under and thus sending usdt via ETH makes no sense due to the fees.



I have access to coinbase and gemini. 



Does this mean if I get usdt in the BSC Bep 20 network... I need that coin to pay my fee?  What coin would that be?   



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?



Would I just get btc and then use one of those anonymous crypto services like changelly to do this?  Or fees are very high if I'm doing a small amount?
