Most of the time, when it comes to bitcoins, i say nothing's for sure, but dude, this one?? Really?? Look, i don't wanna sound like a know it all guy but seriously bruh, this is just impossible to happen, why you may ask??
Because, why would you ruin bitcoins advantage to fiat?? I mean, why make or who would want something that is not controlled by banks also get  under banks?? You see my point here bruh?? That is why i think that it is really impossible..
Just just for me tho,
