Take a look at Steem's one year chart. It is about to explode upward with HUGE amount of volumes compare to previous year.
Also look at the growth rate of Steemit.com from Alexa and it is up from position 19000 to now 6895. Look at the traffic is breaking all time high. I believe this is a coin for a home run if you can hold on to it.
Lastly, take a look on Google Trends. It tells you Steemit search pop since April to all time high.
Steemit still got a TONS of steam left to run. Could it takes over FB and Youtube?
