If Trump want the US economy to grow and people have better life, he should encourage the use of bitcoin.
Not really. If Trump wants to realize his promises,
he needs a huge amount of money and a weak currency, which suggests that the US-Dollar will be artificially weakened longer than many thought. He needs more inflation. For this Bitcoin would not be the right tool economically.
If he needs a huge amount of money and at the same time needs to weaken the currency, there is no better way than just start printing more money. As simple as that. Just follow the lead of aeroplane money, and you will hit two birds with one stone without a miss. And there should hardly be any doubt that Bitcoin, gold and other hard assets will soar in dollar terms.
