There is a huge demand for data storage and data anchoring in Bitcoin, that is the way that things can be built on top of it and that is how it stays relevant for the future.
I don't think the demand is that big. Looking at past ordinal and BRC-20 hype, many people only wanted quick profit. But related to main topic of this thread, most of the USDT activity doesn't happen on-chain anyway, because Tether decide to use utexo rather than continue to use Omni protocol.
Tron in recent years is no longer a good blockchain for transactions, if users care about transaction fees.
Tron is the perfect example where over complcaiting things and having a different currency for fees, designed to be just another gimmick with no actual impact other than headaches and expensive transfers for casual users will drive users away to other chains that are way mroe simplitic, who ever designed the "energy" stuff, probably trying to copy the gas on eth scrwed the network forever.
I fucking hate Tron nowadays. Sending a USDT TRC20 transaction nowadays costs like $4 - for small transactions that's more than Paypal.
Even ETH has less fees. Can you believe that? 3 years ago, it costed like $10 or $20 or even $50 in ETH to send tokens, because of the smart contract. And TRX was the reverse.
And Tron is the only network with high fee to use USDT.
https://gasfeesnow.com/ shows other network cost about $0.001 to $0.023.
