Cryptocurrency is going to be banned when it is a threat to people. There is no need to invent new advanced technology to kill it. But yes, cryptocurrency can be taken forward by inventing more advanced technology.

Because from what I have seen so far, Cryptocurrency is like help that comes to everyone who understands digital currencies and knows how and the rules of the game, so that someone can reap good results from cryptocurrency.
