The stable coins are backed by fiat. What if they got depegged? There are times that I use the stable coins, but I do not trust anyone among them. There have been some fiat collateralized stable coins that got depegged this year and they will not be the last ones.
That being said, stablecoins that got routinely audited, passing the legal compliance such as MICA, and lastly backed by real reserve rarely suffer depegging.
Almost all coins that got depegged this year, or even in 2025 are synthetic stablecoin with delta neutral strategy or CDP with thin liquidity.
I'd still trust stablecoin but only to select ones that genuinely backed by real reserve not some random synthethic overcollateralized fugazi. The biggest problem maybe the blacklisting.
To be fair though, some of the best features that stablecoin have such as 24/7 availability, fast transaction, and easy access are inherent to cryptocurrency, that benefit exist because the underlying network where stablecoin runs thanks to the "volatile" cryptocurrency for making it happen.
Will stablecoins become the standard for international payments?
I doubt it, will because stablecoin is issued by private company, only bank issued stablecoin or in otherword CBDC may have the chance, right now stablecoin barely make up 1% of international payment.
