Very low transaction costs on the TRON network are the top advantages for USDT users. Now we have more choices like USDT on EOS, BSC & Polygon. Ethereum will lose USDT market share if ETH2.0 continues to be delayed.
True, but Tron had been outperforming Ethereum in the amount of USDT on the chains for months, although now it has dropped a bit again. If we look at the transparency reports of Tether we will see this:
(USDT in circulation on Ethereum) Total Authorized: $39,828,710,009.87
(USDT in circulation on Tron) Total Authorized: $38,742,473,246.55
As we can see the difference between the two chains is very small, and having the problem of the high transaction fees that Ethereum has, I think that soon Tron will end up exceeding the amount of USDT in circulation.
