With this we can see that Trump seems to support Bitcoin. I believe this is one of the tricks to gain sympathy from Bitcoin users or Altcoin holders to elect him as president. Hopefully Trump will legalize Bitcoin in the US after he has officially become president.
How can you be sure of that? It's election time and for sure even if you are not in the US, you should know by now that Trump and his political party are using Bitcoin to their advantage, they even add it up to their agenda.
I do not think that he will legalized Bitcoin in the US, we really even don't know if he will true to his words that he will make American great again with Bitcoin. So just stop and see how it goes if he become the next President. And before we forget, Bitcoin is designed to be free from any government control, so regardless of who is going to win, Bitcoin ecosystem with thrived.
