There is one article I read one day, it was saying Bitcoin will end up unexpectedly. But for me those information I hardly believe but anything can happen no body can predict exact what can happen in future. From what I have been seeing it will be very hard to just end up like that because, some countries are now supporting cryptocurrency and even Banks planning to make use of Blockchain technology so.. It will not be so easy to just put an end to cryptocurrency because more people are getting involve everyday. But with some news in the space.. Making the price drop those negative post drop the price of Bitcoin and altcoin price down. But nobody can predict the future.
