Libra's biggest failure was not being able to please the regulators. Since it was centralized, it was easy enough to take down. But truly-decentralized cryptocurrencies? That's another story. Would you imagine decentralized, private stablecoins hitting the market? It would result in a complete "nightmare" for governments. Especially if developers/issuers of such stablecoins remain anonymous.
Since truly-decentralized private stablecoins would be unregulated, they will only be backed by algorithms (or collaterized with traditional cryptocurrencies such as ETH and BTC). Sounds like a far-fetched idea, but not impossible to achieve. This is much needed, especially when existing stablecoins can be easily tracked, traced, and manipulated by companies. We'll see what happens in the long run...
Remember UST?
That was a truly decentralized stablecoin — no central issuer, algorithmic backing, and massive adoption. It helped catapult Terra (LUNA) into the crypto top-10.
But it also triggered one of the worst crashes in crypto history. Its collapse wiped out billions, shook investor confidence, and arguably set off the last crypto winter.
So yeah, decentralized private stablecoins sound great in theory — no tracking, no censorship, complete freedom. But in practice? If the peg fails or demand dries up, it could destabilize the entire market.
Maybe it's actually a good thing we don't have one right now. Some experiments are better left in the lab — at least until we’ve learned how not to blow up the ecosystem.
