Bitcoin and the blockchain are very unstable, no one can control it. So its future is hard to predict, but it will not disappear.
Bitcoin will not disappear, even though the price is now falling. Bitcoin will return to its starting price and even higher. I estimate Bitcoin will stabilize and rise back in April
If we can integrate blockchain features into our daily lives, we'll be the winner at the end. It's a great method to utilize real world stuff, if you ask me.
Blockchain technology will be put into practice but I do not think it will be used as a popular payment method. The price of altcoin is very volatile which affects the price of the exchange.
