Personally, I have no experience with religious people in regard to the blockchain and cryptocurrency. However, I do believe that it is important that we respect whatever views these people may have on this subject though if they have an open mind maybe a little education can help. Always emphasize to them that blockchain technology means transparency and away from the control of a group of people and in some sort can be freedom to many. There is no need to go into the deep technological aspect as that can be so hard to fathom for people already above 60s, maybe younger people can be easily swayed to open their understanding. One thing for sure is that there is no evidence to connect blockchain and cryptocurrency to the myriad of symbols in the Bible.
Why? What are those religious group says about crypto? And why they don't want cryptocurrency?
All I know, religious groups don't like gambling because for them gambling is an evil works. But I think they just need to understand what bitcoin really is and the purpose and uses of it.
Bitcoin and other cryptocurrency are digital currency which is depends on the person if where they want to use it although others thought bitcoin as a gambling.
