I think a common missconception is that everyone will be rich form investing in btc. The whole point is that BTC and other cryptos will be a great equalizer in the long run. It breaks apart the current system and gives everyone more of an equal chance.

The real change comes when more people start earning in BTC. When there are more decentralized businesses, no more regulation to protect monopolies. This is what will make a difference, but it will take time and effort.
