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.
