I think a big problem in Cryptocurrency as a whole is centralization. Originally there was a utopian view where it was a decentralized currency with a level playing field where everyone could create currency by mining, and everyone could own a chunk of the pie. Unfortunately your ability to create currency and to own currency is limited by your current wealth.

Cryptocurrencies are suffering from the exact same problems as fiat. It's very easy to get more currency if you already have a lot of currency while it's very difficult to get more currency if you're starting at the bottom of the ladder. The result is that the people with the most money still control everything and profit the most, while those with little money are getting less exposure and less benefit from the system.

To have a truly "fair" system, all votes would have to carry equal value - Which would go completely against the principles on which Steem was built.
