Bitcoin right now really keeps on increasing its value, I agree that no one can tell when does bitcoin ends. But for me I believe that bitcoin never ends because as long as there is a user and there is an internet connection, I guess it will never end. As long as there are many people believing bitcoin, there is no reason for this to end. There is no way Bitcoin will goes down. As we can see Bitcoin continue growing and increasing as days and years pass by and can be more stable in coming years.
