But here is the question, do you think Bitcoin can overshadow the relevance of dollar in the future?
The US dollar plays two major roles in the world economy. It is both a major part of global foreign exchange reserves and the primary currency in global trade transactions. Which role of USD are you referring to or both?
Theoretically, bitcoin could also take on both of those roles instead of the USD, but would it be easy for the US and the world to let bitcoin replace those roles for the USD? That's the problem, because if the world agrees, bitcoin will easily replace the role of the USD, but if not. Bitcoin is unlikely to replace and surpass the importance of the USD in the economy.
