Want to earn more on steemit? Don't sell your earned steem!

According to this statistics : https://steemit.com/steemit/@penguinpablo/daily-steem-stats-report-june-28-2017 Steemit popularity is starting to grow faster and faster and there is reason to think that steemit will be very popular in a year.

What doest it mean?

It means that many of people will be looking to get some extra steem on their account to earn more money from posting. The price will start to rise fast and there will be much more buying power than selling on the market. If you earn 100$ today from a single blog post then if u keep saving it in your wallet you will start to earn more and after a year this 100$ might be worth 1000$ if steem reach 18$ price what is pretty possible.
I also seen somewhere chart that shows account creation on steemit every month and it is parabolic in a few months it will become vertical what means a HUGE raise in popularity. I know that steem will be worth much more but there is thing to consider if Steem blockchain will be able to scale so much traffic?
