The document is small and worth reading. And in practice, such recommendations will soon become mandatory. And stablecoins will have the same requirements as international currencies, which means total KYC and all other delights.
If a broad regulatory framework is established for cryptocurrencies, I do not think that we will need stablecoins, as it will be easy to create a bank account in dollars and buy Bitcoin directly from banks. I do not think we will be allowed to withdraw Bitcoin, but it will be the next step after extensive regulation.
If this broad regulation does not happen, then most likely stablecoins will be regulated such that you need KYC to create a wallet, but due to the inability to regulate DAI, these steps will not change the non-KYC stablecoin option.
https://daistats.com/#/I store most stablecoins in DAI, but I don't like this picture at all. Previously, DAI had a lot of stablecoins in the collateral and they were heavily dependent on USDC, but now there are a lot of RWA (Real-World Asset) in the collateral. This is also bad.
But one question still remains - stablecoins can be issued from anywhere in the world. Not sure how the Bank of International settlement is planning to enforce it's regulations onto them.
Unfortunately, this issue has not yet been resolved, how to make an ideal stablecoin, independent of regulators, and so that there are no problems with trust. Any algorithmic stablecoin requires excessive collateral, and even for DAI this figure is more than 300%.
We all want decentralization, but no one uses the Ethereum Classic ecosystem, and it is almost dead. The same will happen with other stablecoins.
