Many people do not understand or do not want to understand the advantages of using Bitcoin because they have most likely encountered Ponzi schemes in their lives. Their negative experience tells them that they should avoid experimenting with investing in such projects. To explain to such people that Bitcoin is a financial system without any censorship, it is enough to explain in simple terms how this technology works. In order to use the Bitcoin network, they do not need to invest large sums of money. Only by understanding this can Bitcoin be accepted, no matter how negative such people's experiences may have been in the past.
They have tried to explain as simply as possible but they still do not understand and the fact is that they are also tech savvy and only believe in local money and not in digital currencies like Bitcoin.
It's useless to explain it, because their mindset will also not be able to be changed, always related to gambling, MLM and the like.
They don't even touch crypto and even if they have to force to understand crypto it will be very complicated, so leave it alone and they will shut up on their own.
