Bitcoin never dies, it never will, in my opinion. If you are wondering why, bitcoin is indispensable when there are so many investors and money in it. Its lack of control and decentralization make it an excellent choice.
But we also have to be able to accept that bitcoin can die anytime so that we can be ready for whatever the situation will be. Nowadays, bitcoin has become something popular and many people want to own more bitcoins. Lucky for people who have been in bitcoin for a long time because they may still have many bitcoins.
The presence of bitcoin can help the current payment system but because bitcoin is decentralized and no government controls it, this is what the government does not like, so several countries have not approved it. But that will not stop bitcoin from becoming more famous in the future so many people will use bitcoin as an investment or other things. So bitcoin will still be around for the next few years, while for decades later, we leave it to bitcoin itself and those who use bitcoin.
