I concur that bitcoin, like gold will serve as a store of value and not disappear.
But most people today have already trouble to make both ends meet, so the majority of people don't have the extra wealth to store it through bitcoin. Most people do not own gold and neither will they own bitcoin.
Well, sure. To store value, you need to have money to store in the first place. The thing is, Bitcoin is just a tool that they can take advantage of when they're trying to protect their money from inflation. Bitcoin isn't some magic bullet that could magically get people out of poverty; which for some reason people think is the case.
