See I have this problem, I am living with older people since I lost my parents at a very young age and I get so attached with crypto and I am making money out of it but the problem is my grandfather and uncles do not understand what Bitcoin is all about, believe me, I've tried to explain but they just won't get it. What can I do? They kind of believe that I am wasting my time.
How do one educate the illiterate about digital currency?
This is funny;D, the headline isn't contradicting your explanation. Just because your grandfather doesn't understand bitcoin doesn't mean they are not the right people to live with, I enjoyed every moment I had with my granddad and I still wish they are still alive today, you wouldn't know the value of old people around you until you lose them, this is not joke/clout chasing my friend.
On the other aspect they not understanding Bitcoin enough as digital money, there are plenty of materials online as a beginner guide for young and old people to understand bitcoin, if you know bitcoin as you claimed you're making money online, you should be able to convince them, it is all understanding the concept, you don't have to go technical to make them understand the concept of bitcoin.
