I don't know the name of your country but if our older parents let's say from 60 yrs and above in Africa can give cryptocurrency a trial our Economy will boom but funny enough most of our youths still perceive cryptocurrency as scam.
To be frankly speaking, you just need to understand that the general adoption of Bitcoin does not make a country's economy boom over night, if not countries such as "El Salvador" and "Central African Republic" who just made Bitcoin a legal tender would have been the most richest two countries by today, but yet El Salvador is ranked 119th in the entire world. And moreover, there is no age bracket to who can & who can not invest in Bitcoin, in as much as they understand the basic concepts and are willing to bear the risk. But it will be very unfair to just convince an elderly man who has no knowledge how the project works, simply because you are eager to earn a commission from an exchange affiliate
