Yeah there are two totally separate stablecoin markets.

USDT on Tron is the utility one for savings/payments in inflation-ravaged areas.

Both USDT and USDC on Ethereum is the speculation one used for unit of account in offshore exchanges, leverage/liquidity pools, etc. Mainly for large traders who don’t care about the higher fees and are riding on the remaining liquidity network effects and momentum of the Ethereum ecosystem. 

 They sound so “enticing”
