I don't expect the same drama to happen with democrats, even though I believe that the crypto initiatives will always be introcued as a dramatic scene to enjoy watching with some popcorn as long as the whole sector is not fully adopted by the american system.
As for the coin lunched by the Biden's son, I think he is just following the wave as democrats are not ruling the politics. But later if the democrats win the presidential after winning in the midterm election, it will not be that easy for him to start such a scam without being subjected to agressive critics.
Well, Biden's son isn't a government official or politician, so he's free to launch his own coin. Not like Trump which launch his very own crypto while he was in office. Two completely different things. Trump's situation can be called a "Conflict of Interest". Especially when he profited off the presidency with both his "meme" coin and multi-chain token (dubbed WLFI). Apparently, Trump made a deal with the UAE to pour money into his World Liberty Financial project.
The hype is starting to fade after Democrats successfully secured the majority in both chambers of Congress (House and Senate). Both WLFI and TRUMP's ("meme" coin) death is certain now. After the presidency, they will simply fade away into oblivion (starting with the "meme" coin). Yet, Trump's supporters will still buy these coins out of loyalty. We'll see what the market decides in the long run.
