This "stablecoin" is just yet another attempt to scam people by selling worthless tokens.
It sounds all nice, but there's just one problem: as with any Ponzi scheme, the value of your investment is stable until the bottom falls out, and it becomes worthless. Your money, meanwhile, is in the pockets of the scammers.
The only problem in your argumentation is that according to their
announcement it is the complete opposite of what you said:
One of the beauties of the solution is, that it works without issuing or acting through a stablecoin, by enabling the Euro directly to behave as if it was a token on a blockchain. and
the counterparty could now be a Euro account holder, without a single, centralized intermediary ever controlling the two assets that are being exchanged.
This means: You don't invest into it, they just make your normal bank account more powerful by connecting it directly to blockchains. They don't sell a token and you don't give your money in the pocket of someone else, so nobody can scam you.
They basically tricked you with this: You can't claim they are scamming you because it is completely non-custodial and you don't invest into it.
