It is interesting how perspectives on Bitcoin are changing. Traditionally many thought Bitcoin would compete with and potentially weaken US dollar worrying that if people used Bitcoin more dollar global standing would suffer. However recent comments from Trump suggest different idea that more Bitcoin use could actually ease pressure on dollar. Maybe this happen if Bitcoin acts as another option for investing taking some of demand off dollar or if accepting crypto helps US lead in new technology boosting its economy. This new way of thinking shows how our understanding of cryptocurrencies in world economy is still evolving.
