Lots of claims like this have existed even before now, so it's no new thing that a random guy can just pop up and start advertising projects that might later end up being a scam or was created as a scam to steal peoples funds. Op if you really had good intentions in sharing a great project, you first impression matters a lot, and you sounded more like a someone with limited information about the project in which you are trying to expose to us. From my perspective I don't think any alternative to cryptocurrency is created already, since crypto is still at its acceptance stage, meaning this is just the beginning of cryptocurrency and we'll be having lots amazing experience once cryptocurrency get accepted by more nations. Its almost impossible for fiat to be eliminated as a currency due to a new technology, and before cryptocurrency got to where it is today, it took quite some years and reputation to get this far because of its decentralization nature as government aren't able to have control.
