There are so many ways Bitcoin can be promoted especially here in Nigeria and wold wide.
Firstly religious leaders play a very interesting roles in the life of people and are seen as role models and mentors some see them as a father figure, so what ever this set of people tell there followers that is what exactly they will all do.
With the numbers of churches and mosques that we have I know if Bitcoins is been enlightened to us through this regions then people will trust and believe in BTC, Bitcoin will surely go more far and spread wide with this ideas.
TBH, I can't think of a reason why somebody must connect religions, churches into Bitcoin.
I can't find any churches that are promoting any crypto project at all. I don't know if religions promoting Bitcoin will be good or bad, but I don't think that they will promote it at all. I mean if they can't benefit from it then they will not do it and besides, not all of the churches know or has been engaged into Bitcoin or crypto in general.
Secondly Bitcoin is better than saving in a bank because it appreciate while it is been saved in our wallets and it is also an investment, so many people complain from there day to day activities with the local banks of been debited without cause and reducing the expected savings this is not a good reputation and Bitcoin has solve this aspect of issues, with the security of wallets, hard ware and software wallets fraud is been reduced making both the old and the young to believe that they are saved from been scammed through BTC.
Well, you are thinking of telling to these savers to just invest their money into Bitcoin instead of saving it to banks right?
I can't blame those who wants to save their money into banks because maybe they are lacking of financial literacy thus, they grow up with a mindset of "Save all of the money into our banks".
Another one is there are some savers who can't take the risk of investing into Bitcoin. Do you expect that all of these savers can take the risk of holding an asset that goes up massively, but goes down massively? Do you expect that they will just be ok when they see their investment or in this case savings' account going down because of volatility? I don't think so. After all, there are some factors whether you will invest your money into Bitcoin, or to just let it save in banks. Those elders who are saving money into a bank can't take the risk of taking out their money from banks and put it into Bitcoin.
