Well, have you thought about this idea that Bitcoin can be like a religion too? With some level of fanaticism, there can be people who are considering the Bitcoin community like a cultish one but then again all form of organization in varying degree has this energy and can even be used as a bonding agent. Now, in my opinion, while this idea can be a big welcome to some, this can also turned off those people who are not inclined to take up religious matters into their lives.
Nobody is saying that Bitcoin is a religion, youre the first person thats saying that here. If someone doesnt want to join the Bitcoin community it doesnt have anything to do with bitcoin as a religion. Though the quote you have posted is right in the sense that there have been people who were able to change their lives with the help of Bitcoin, by investing in it and some of them by trading it. So, thats it.
It can help you get rich, but for some people it is not the same story, some have ended up losing their money instead, so its not something that saves everyones ass, if youre lucky it would work for you. Id say for sure that it worked out for me, but my knowledge helped me of course.
