There should be a thread: Will Trumpcoin still exist after Trump's tenure? because that's what's likely to happen after Trump finishes his term. This Trump coin may be doing well right now because of Trump's support for Bitcoin, but I don't see this meme lasting more than a year unless he continues to shill it, but its existence is limited to where it got its name, tenure in the White House.
So its a big no for Trumpcoin to replace Bitcoin, and yes, this Trumpcoin will vanish after Trump's tenure.
