Bitcoin is here to stay I believe. There are so many technological benefits it carries and it is about time that other countries and organisations start accepting it as a currency
bitcoin will continue to exist wherever we are, it is unlikely that bitcoin disappears from this world, because we can see bitcoin is the king of all other altcoins, if bitcoin disappears most likely other crypto money will go away by itself, bitcoin comes to complete the world internet, bitcoin will always exist, because we can see that now there are several countries that have legalized bitcoin for their currency.
