despite a lot of unsightly news from early 2018 to the present, this will have no effect on bitcoin in the future. yes, bitcoin will be a promising coin for its users. I think bitcoin will be the first digital currency to become a global currency. consider the current situation as a bitcoin feasibility test to become a global currency.
we can talk about the global currency only on the network, but not in real life. I am sure that Bitcoin will not be able to replace the real currency, since for the majority of the world's population this will lead to huge problems and difficulties.
