I don't understand one thing, if USDT is based on ERC-20 network, how do you prefer it over TRON? TRX is one of the most used currencies in casinos even for withdrawals because it has a low fee and the transactions are fast, while ETH has very high fees, like Bitcoin, they are the strongest but most expensive currencies to withdraw.
What advantage do you see USDT in the ERC-20 network? What I do like is playing with USDT is very different, well maybe you have a different approach than mine.
USDT firstly is created on Bitcoin network, with the second layer OMNI. Tether company decided to build it up and expand it to Ethereum network (on ERC-20 chain) to have cheaper transaction fees and faster block confirmations. They are past stories. The reasons and advantages of USDT on ERC-20 chain was broken with Ethereum network congestion or very high fees in past 2 years.
TRON (TRC-20 chain) join the party and now we also have BSC chain and give people better means to move USDT with faster transactions together with lower transaction fees. ERC-20 USDT can give fast confirmation but only if people accept very high fees.
Platforms will accept what are secured and give them as well as customers benefits. TRC-20 and BSC chains for USDT will soon be considered by platforms.
