Pros:

1. Tachain has already had its MVP lauched on AppStore. It comforts investors that the team is indeed making progress and the Tachain project is marching forward.
2. Getting itself exposed on Steemit is already a huge advantage over other project teams as Steemit gathers so many blockchain lovers and investors.

Cons:

1. White paper might need to include more details to address the concerns of investors. For example, analysis about the bottle neck of the project and analysis about the risks the project team is facing.
   2.Another concern is about the competitive landscape. Tachain might need to talk more about how it can differentiate itself from other competitors who also try to grasp the market share.
