I stumbled upon the article "What happens if bitcoin succeeds?" in which John Danielsson, Director of the Center for Systemic Risk at the London School of Economics, argues that the inequality between rich and poor will be further exacerbated.
I think we should not shy from the fact that it may be a possibility of an increased gap inequality.
Though, it seems to me that unlike other assets where accessibility is not as easy, crypto actually provides some 'higher' means of getting involved than anything else. Take gold for instance, you'd only be able to store gold as valuable asset if you start with a large sum. This is not the same as with crypto where you can start with as little as $10 and where there's so much availability around with lots of platforms.
With BTC and crypto in general, the knowledge is there, the resources are all there to learn, it is only a matter of wanting and doing. This level of accessibility and availability to all has never been around before, not for any assets I know of.
