This sphere will live on till some destiny time even for a long time frame. even though presently much less attractive and seen does not have a super future but for the long time, crypto will continue to grow. so do not be too think about the modern kingdom and what's owned.
I think that in the future it is a development period of cryptocurrency. now is the beginning because cryptocurrency itself is not yet a real currency. it will not replace fiat money but the cryptocurrency will occupy money in the digital era, and I think it will soon begin. crypto will survive, and in time everyone will fight to have cryptocurrency.
