fully, I haven't thought about that yet, and if it really happens in the future there is a possibility that the closest altcoin to bitcoin will replace it. but for sure I am sure Bitcoin is not dead, even Bitcoin orders always occur every day.
What if the Bitcoin dies when you have a lot of investment in it? It is a very dangerous moment for if it happens. No one wants to see the Bitcoin to be dying in future because they see that Bitcoin has the potential to give us the utmost possible profit. Bitcoin users will not let the Bitcoin die and it is clear that Bitcoin has been surviving since long only because it is out interest and best source of long term investment.
