The more mainstream stablecoins become, the less likely they are to be just "convenient transfer tools."

Early USDT addressed transaction issues: transfers between exchanges, over-the-counter currency exchanges, on-chain settlements.
Later, it solved payment issues: low cost, cross-border, fast, especially more evident on networks like TRON.
But as the scale of funds carried by stablecoins grows larger, they will inevitably face a third problem: regulatory compliance.
The freezing of two TRON addresses with 344 million USDT is a signal of this stage.
The mainstream adoption of USDT is not just about more people using it, but also means it will be more deeply integrated into real-world financial regulations.
Therefore, the future of stablecoins will not only be "faster, cheaper, and more liquid."
There will also be stronger address identification, faster freeze responses, and more complex sanctions cooperation.
The more they resemble financial infrastructure, the more they will be constrained by financial infrastructure regulations.
