I think blockchain already have an impact to every people's life. As it gives people more opportunity to change their life by being rich or poor. Since there's still no guarantee you'll succeed in this industry. If this technology spreads to every people for sure it could also change the society's perspective and a lot might enter the market.
Too much hope for you to be rich is not enough, you have to exert effort for you to gain what you want to achieve like studying, experience and emotion.
Blockchain technology isn't doing that. It isn't invented to make people rich. You are talking about speculative trading/investing, when you buy SOMETHING and hope it will go up in value, even though most of them are backed up by nothing else then promises, hopium and greed. This could have happened with trading cards. Downside of speculative trading/investing is that it might as well get you rekt. That's pretty much same as gambling.
Blockchain tech can change society but it isn't doing that by making people rich.
