And, as much as I hate to say it, the same goes for Bitcoin. Only the most rabid Bitcoiners will move here, just for the native Bitcoin integration. And a lot of people actually don't like Bitcoin.

Most "normie" Bitcoiners know that the apps they are currently using will eventually use Bitcoin because everyone will eventually use it. And they don't mind spending fiat, so long as they have some or can convert at PoS. Which they all can, now.

Allow monies to compete and/or allow for conversion at PoS. Don't make "use only my favorite money" your main feature. That is not a feature, it is a limitation.
