Suppose you woke up tomorrow morning and found that Bitcoin had dropped to 0$, or that Bitcoin had disappeared or been scammed. How will you be at that moment?
Bitcoin price is not permanent but i believe that cyrpto currency will not disappear unless there is a great distruction or a great war of different countries. Bitcoin price will not easily lost its value.
This is true, bitcoin couldn't go away, it will stay because we are talking about even nations investing into it right now which means that in order for it to "go away" it needs to have some coding error or something and I am sure that something that reached 2 trillion dollar market cap as a whole (all of crypto) will already have enough people trying to find any error, and there must be none since bitcoin never had anything like that.
This is why all those big companies and nations will keep on buying as long as the price goes down, and they will make profit from it when they hold it longer than the retail investor. It is not going to happen at all.
