When adoption comes, the ols people will find a way to also adapt to the new adoption. The old people have been in existance and are surviving before the existance of modern technologies, and there are still many old people who dont have access to modern technologies and they are adapting to any environment they are. In Nigeria today, the old people who dont have any electronic device like mobile phones are still copping with the cashles policy. 
So i believe that in adoption of crypto across the country, old people will adapt a surviving strategy.
