Will Crypto end, No. Will BTC end, maybe. BTC was the first crypto and its value is derived by the fact that everyone mainstream is investing in it. There are "better" coins in that they are more developed but BTC is what most of the mainstream understand.
This is the reason and there is another reason that the bitcoin is increasing and the future of the bitcoin will be very high as much as I know the bitcoin I can see how the bitcoin is increasing and then how it is getting more famous with the time, the journey of the bitcoin is unstoppable and the bitcoin will help all the people to increase in the value and the price will be high in the future.
