Bitcoin can die only if internet dies but I don't think that will ever happen in future as internet is advancing day by day and apart from that I don't see any valid reason in which bitcoin can die in future.
Indeed.
There's no way internet dies as well as bitcoin. These two are the future.
Bitcoin is the top cryptocurrency as of today. Proving itself in the market. That's why alt coins are made. They try to follow the success of bitcoin, so how does it die?
Developers are improving and doing experiment to the system so it will grow more.
Likewise, Japan also legalized bitcoin as a currency and for sure many countries will follow that.
So it means a good sign of the world economy.
