I don't know how many time survive bitcoin. It's future so we don't tell this about this properly. I don't think so bitcoin can be survive much more.we see now bitcoin success. If you see last one year history of bitcoin success. then we don't think about survive. Last One year we see bitcoin price increase day by day. so many country legalize. so many new merchant accept bitcoin. now we can do all thing by bitcoin. I think at this moment bitcoin alive for long time not a survive time.
