The way I understand it, part of the goal of crypto-currency is to give some power back to the people, power that banks and large financial institutions have wielded over the common folk for a long time. And make no mistake, this is a corrupt system we're talking about, as has been well documented over the years.

What's the point?
The point is that cryptocurrencies allow people to use their money free of control by others -- government, corporations, and the so-called "wealthy-elite". There are several important distinctions that need to be cleared up.
1. The wealthiest people hold very little money relative to their total assets. An equitable distribution of cryptocurrencies would not have any effect on the distribution of wealth.
2. Cryptocurrencies do help protect us from those that want to control us. In the fiat case, they use their wealth and influence to control how we hold and use or money. In the cryptocurrency case, they do not have that same ability, regardless of how much of a cryptocurrency they hold.
3. It is a mistake to believe that the end goal of cryptocurrencies is to be an investment. At some point in the future, adoption of cryptocurrencies will reach the saturation point and their values will no longer rise. Hopefully by that point, most people will realize that cryptocurrencies are intended to be currencies and not investments. ICO coins and other crypto-based assets are clearly misnamed when they are called cryptocurrencies because they are not really intended to be currencies.
4. The volatility in the prices of cryptocurrencies has more to do with speculation and mass hysteria than pump-and-dump. Contrary to the popular mythology, "whales" are not behind pump-and-dumps.
