You are absolutely correct. Without the investors who have invested money into steem, steemit would not, and could not exist. It needs both to survive in the future though. It needs quality content to keep it going, as well as investors. The content creation aspect of steemit is what sets it apart. It is what draws some people to steemit who would have otherwise never invested. The community aspect and the material bring great value to the platform. We deffinately need people who are willing to invest time into steemit. Both investments are valuable. That's the beautiful thing about steemit. You are not only able to invest money, you may also invest time and be rewarded the same. That may not make sense to some people but I fell like most people would agree that time is money.
