Bitcoin has no reason to die. No need to worry.
Don't you know that everything on this planet have a lifetime? Everything dies eventually, either that is life or something electronic, everything has beginning and an end. So does Bitcoin. For now it is growing and i must say that i like that, more and more people are using it, and because of that price is rising. Bitcoin will not die soon, but it will happen... eventually.
If we think that way, it will come to an end. But I think bitcoin will be the vehicle of change in the future.
