Anything is possible but not this going to zero thought. Cryptocurency is struggling to get worldwide adoption which I believe will happen but it will take a while through the processes part of which is to end scamming from projects or devs, ending the journey of seemingly useless coins and tokens and nany more.
The government-backed crypto can crash the entire market but the possibility of happening odds is unlikely. Zero price means there is no buyer or seller, at least we have a few decades with this technological model, I think so.
