If you ask me I will say that Bitcoin is not replacing anything, not even gold like some people do say. Bitcoin is good, but it will be a thing on its own and not serving as a replacement. There will still be gold, gold cannot be replaced, everything has what's makes it very important and by the way, gold is one of the most valued stocks in the world. I don't see why anyone would reject it.

Cryptocurrency is something different and interest varies, everyone has what they like best. That you like cryptocurrency the most doesn't mean that other people are going to like cryptocurrency too, they might decide to go for something else they believe is going to benefit them.
