Any suggestions for this Steemit Infographic I made?

I am an infographer and I am learning about different kinds of cryptocurrencies and how they are used. I chose to do an infographic about Steemit, because Steemit is an interesting concept. Now, I would like to hear from you guys, whom I consider experts in the subject, on how I could improve it. Then, I can make a final version of it and release it elsewhere too. 

I would like to know if it clear, if the color scheme works, etc.

Thank you in advance!
