Bitcoin's decentralization promotes the fairness of global currencies and protects its holders from inflation.
Bitcoin does not achieve global wealth equality. It will only benefit those who are really rich or the rich who buy it, and make the rich who have the funds to buy more Bitcoins become richer.
The richer get richer still applies in cryptocurrency but at least this time there is a chance for the poor to get richer since they could hold tokens to expect enough return one day.
Equality is not ideal really but the people to have enough will have contentment. The world will be better to have people who could say they have enough than people who will revolt to make more money. Sometimes its not good for the poor to have more money, they eventually see their past enemies be a peony.
That sentiments still applies as rich people do now what to do most to maximize their benefits out from this industry,
the capabilities to buy more asset and keep it on hold still favor the rich.
But, it's also gives opportunities to those poor people who manage to invest with crypto or Bitcoin and trust this assets
to bring them good hope to earn a lot and change their lives.
