This is happening in some places sun valley is a very small growing number of churches in America that are really accepting online donations through cryptocurrencies.so in future it will be a great ideas in other continents even in future crypto-christianity will be the secret practice of Christianity 
well bitcoin is a currency that has already reached a worldwide level of acceptance, that's why churches can no longer ignore bitcoin, since there's nothing wrong with someone donating bitcoin to a church. now churches will have to create conditions for people to make bitcoin donations. One thing I've been asking myself:
Where do these church donations go?
anyway it seems that this is a question that would bother me if i asked in church
