I think there are some sound-bites from Trump-45 calling it a scam (in strong contrast to Trump 47) but even then then he never tried to do anything about it. If trump gets on Truth social tommorrow and fires off a tweet about how Bitcoin is a chinese threat designed to destablize US hegemony and circumvent tariffs and he's going to sign a legally-questionable EO to ban it, bitcoin's price would go up "bigly". Same would apply to the EU or any other major economy, although i will grant that it might not be to the same degree since nobody pisses people off the way trump does.
I.e. GameStop is all very impressive until you compare it to anything finance actually dumps money in by default.
If the pyramid is isolated it tops out somewhere a lot higher than now and then collapses for lack of a place to sell to next or an actual return.
