I do not see this happen soon but its of course possible, no one knows what is gonna happen with the bitcoin itself.
So yes there is a possibility that that bitcoin is gonna disappear for good but I think this will be in about 20 years from now so we still got a lot of time.
It is post like this, that adds no value to the discussion. Put some more efforts into your post, and quantify why you are saying Bitcoin will disappear in 20 years. We cannot simply post crap and expect
campaign managers to pay for that. There are enough Sig haters on this forum and you giving them more ammunition, when you post stuff like this. Bitcoin will not disappear, until there are nobody
running the nodes or using the currency or keeping the Blockchain going. The price will go down, but the bitcoins will still be there... Let's contribute constructively, when we post please.
