I think bitcoin will persist as long as there is a country that don't prohibit bitcoin. I see now that bitcoin prices are getting down and making investors bankrupt due to banning bitcoin in some countries. If until all the countries that exist in this world banned bitcoin, then bitcoin will die. There is no solution to overcome it because when it is concerned with the country play the law.
I think bitcoin's death is hard, even though most countries are forbidden, but bitcoin needs the internet, the most basic need here, and maybe its price will be low at that time, but it will still be there People dare to use or invest.
