According to my opinion bitcoin is 100 time better than Gold as their technology of blockchain...bitcoin is long term investment.. so peole try to earn more and more from bitcoin..
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.
