it does not rule out the possibility, but we need to know, if there is a cryptocurrency that can take over bitcoin it will take 5 to 10 years. How come, since the arrival of bitcoin he has become part of our flesh and blood .. while saying new crypto as a substitute is not easy, the point is bitcoin is still bitcoin, as a single and parent. as for innovation in growing the bitcoin revolution in the future.
Simply because bitcoin has no authorized organization that controls it nor some owner who keeps saying things that don't really exist on their project. Bitcoin has been there and no one has to promote it instead everyone who has it promote it in their own different way. This is why Bitcoin is hard to beat by any other top altcoins out there. They cannot beat those promoting BTC without payment.
