That's true, some people are too spontaneous and invest money without any knowledge of crypto so research is necessary. I always pay attention when owners put much efforts in creating a community and is is to be in touch with teams of their coins. That's why Im supporting FuturoCoin, also because of their policy which aims to make crypto more popular to people who were not interested in crypto before
Only the younger generation will be interested in cryptocurrency now and in the future. I can hardly imagine an elderly person who can pay for utilities or buy any goods using cryptocurrency. This requires certain knowledge, and it is already too late for old people to study.
But there's still older people who loves to read and learned, it's not only the young generations but also needs to consider those who's willing to take the chance, there's some people out there even in their ages still wanting to learn how things works and how to take the benefits, they can be consider even the numbers is not that much compared to the numbers of new generations who's really can fully adopt everything inside this new system.
