We don't even know what will happen in the future but people are speculating that Bitcoin will fail though Blockchain technology is what will remain. It is a possibility but I don't think people or investor will let it happen.
Bitcoin has remained strong more than a decade after its creation. The death of Bitcoin was predicted by numerous analysts and experts during this duration. For some, the ban by China in 2013 was a possible reason. For someone else the listing of Ethereum in 2015 meant immediate death to BTC. And even in 2017, a number of experts were predicting death for Bitcoin, after Bitcoin Cash and some other coins forked out of it. I am sure that such predictions will come out in the future as well, for different reasons.
Not long enough we experience huge dumps but I've never felt that will be the end of Bitcoin. BCH is just a clone and I don't see this coin will strong enough to compete against Bitcoin. The longevity of its existence become stronger and come to the point that garners more attention to the public, and makes people think that Bitcoin is better than of gold and USD.
