In fact, it is very difficult to explain it to our parents who have no knowledge of crypto. My parents at first did not believe that money could be made from cryptocurrency. Then when I cash out some money and showed them hard money, they believed. For this they have to give proper knowledge first.
the answer is simple, they have never known this before, so they become hesitant and afraid to learn about cryptocurrency. however, most parents will be very wary of the types of investments we offer, as they also have their own perceptions of investing and fraud. however, it all depends on how you can convince them to learn about this.
