The problem is that many, many kids people, consider crypto coins as simply a trading game akin to Top Trumps or Pokemon cards. They don't see the real fiscal value or future benefits of real-life application. That's why crytpocrap is still around and being traded. Of course, there is also a responsibility for the exchanges to stop trading them too but they don't give a fuck whilstever they are making a profit and raking in commissions.
