I am not aware too much that bitcoin will not forever but in fact i do keep have a lot of faith and trust on how all cryptocurrencies working in and out and improving day by day and as a matter of fact also we do know all cryptocurrencies recognizing as a main coin of all crypto currencies in that way we can see all the companies that are already involved in the world of crypto currencies are making a way to have a better technology for the good future of all people around the globe and for me bitcoin can last forever until there is still cryptocurrencies in every part of the world.
