Bitcoin wealth distribution is more uneven than it is in today fiat capitalism. Its also unfair, 80% of the natural resources (mined coins) have been taken by a handful of people, and half of the world doesn't even have internet access.

So a new currency is going to help create a moneyless society? How does that work exactly?

What way? As mentioned in the previous comment, bitcoin wealth distribution is extremely uneven. Moreover, now bitcoin is starting to being used by big players, financial corporations and the like. Rich become richer, poor become poorer, as usual. There is no way bitcoin can even slightly reduce poverty. It may be used as a tool for... interesting purposes in the future, but it may be also used by criminals, terrorists, and secret services (like gold and paper money). It is just a tool, not a special purpose tool.

What do you mean communism was not risky? millions were killed....

Exactly. There was (maybe there still is) a window of possibilities, but an extremely narrow one, affecting a very limited number of people. It changes nothing in the existing economic system.
