There are already a number of large market cap, global-ish fiat currencies (USD, EUR, etc.). Black Rock starting their own, even as a Bitcoin affinity scam no different.

A crucial feature of #Bitcoin is that anyone can run their own fully validating node. Anyone can assert that they’ve received funds without trusting a third party.

Your scenario leaves behind that assumption—namely that an organization like Black Rock has control. We already have controlled fiat currencies with significantly more reach. One more corporate player is not fundamentally different from the status quo.

If people are fooled by an affinity scam, that’s unfortunate for them, but detecting and avoiding traps is an inescapable facet of life.
