Of course, I doubt about destroying stablecoins, but they will take measures for sure. They will impose taxes, introduce some prohibitions. Some countries may ban the whole thing in principle
The probitions will never work and did you see so many prohibitions on bitcoin in the past? that proves if that will be useless. The government has no choice other than adopt crypto.
So many banks and big companies have been starting to adopt crypto. The government will never able to ban crypto or stable coin.
This digital currency will always exist in the future. They can only give taxation.
Prohibitions will not work on decentralized currencies like Bitcoin of course since they are always easily found and available on p2p networks and not just on centralized exchanges.
But stablecoins are by nature centralized. If they are banned, no regular exchanges will want them and very few p2p people do Tether swaps,,, much less other stablecoins!
