The US dollar is the gold standard currency of the world. If you want to buy oil from any OPEC member nation you have to do it with this currency. The federal reserve bank and others monipulate gold silver and other currencies to keep the US money king. They have gone to war and overthrown governments to keep it King.
Bitcoin will fare no differently, it may do for a while but eventually there will be a monipulated crash. If not then they’ll tie it to the US dollar some way.
