Altcoins are very different from BTC, there are so many of them that are very shady and i don't even think Trump will be interested in meeting these 'leaders', as you call them. During the campaign, Trump said a lot about BTC, but i don't think that means the president-elect will begin to associate with 'altcoin leaders' or people who create altcoin projects, he is the POTUS, so he has to be careful with what he endorses.
