It's hard to compare a free game from an extremely well-established franchise and well-respected company to a decentralized internet currency which shakes the very foundation on which the financial system is built.

You are very right that bitcoin has the potential - and indeed has had it for a very long time. It is however a very different endeavor than a game. We constantly see new initiatives - Steemit included - which all promote and advocate cryptocurrencies in general, but for the average Joe to pick it up we still have a long way and a lot of trust to go. It is for this very reason that continuously smoothing the entry for newcomers and inspiring them with appealing services like Steemit is paramount.
