bitcoin will exists as long as i live as i will always have the blockchain.
The blockchain won't be very useful if the miners cease and you're the only person using it. The blockchain will slowly fizzle away if something superior comes along.
Bitcoin analysts says that Bitcoin price will have an imminent slump in days to come.
I see these kinds of posts on a regular basis, and I have to wonder whether any of the posters actually believe it, or are just trolling/pumping/dumping.On the remote possibility that you actually believe what you're posting, let me point out that if any "analyst" could accurately predict that the price was going to go up or down, they would become very rich very quick. The price is what the price is, and reflects the sum total of all expectations of rise/fall.
Some are trolling, some are just niave, and some are just looking for any sort of clues about what will happen.
Until the internet is gone. There is no reason why bitcoin won't last or be around. Its value is unpredictable but it will continue to be widely used. There was a document someone had posted on here where a gentleman suggested that bitcoin could potentially see 50 million users on the network by the end of 2015.
Again I think the only way bitcoin will die is if something else comes along that is far better and people will abandon bitcoin en mass.
Forever until me die
