You keep quoting yourself as having written this:
There is no really fixed price in general or something as i want to make sure everyone is able to participate, just donate me if you think it is appropriate.
But you also wrote this:
If you want a "lifetime-prayer-service" which means i automatically will include you EVERY DAY into my prayers at night, send me 1 BTC.
What if you forget one night, or more? What if you revert to the atheist you used to be, or merely agnostic? What if you lose your "Lifetime Prayer" recipient list through some (god forbid) disaster?
I don't want to be rude, because I don't think you are outright trying to scam people. But you wouldn't be the first to
prey on peoples fragility in the name of god. It's usually the very vulnerable among us who are seeking the attention of god and the ones who claim to have him on speed dial. And now here you are asking them for their money. To me it makes you look nothing like samaritan you wish to portray.
