However, it is still possible to buy a token from investors.
I'm confused, what do you mean buying token from investors?
But can it happen that tokens will completely disappear from the markets. Today their recession is on. Is it possible that the cryptocurrency will be forgotten by society and something else will take its place?
Disappear? meaning every tokens have been sold? What we have seeing is a bear market, how will society forgot it when some of them have real life usage or most of them are still being patronized even if this worsening market conditions? Maybe some of the tokens will die, but I'm sure there are hundreds being born every month so the cycle repeats again.
