I do not know why he is trying to convince trump and  Warren Buffet. who he should convince, are the people. the more people in the world use bitcoin and other altcoins will oblige any government in this world to accept bitcoin and other altcoins as a means of payment. The people at the end is who's in charge. Imagine if 90% of Americans went on the streets and went on strike demanding that the government legalize bitcoin? Do you think they would not legalize? they would have no choice, so I believe that in the future all governments will not have a choice, they will have to accept legalizing bitcoin and other altcoins
