Just using these two applications, if it can take even 5% from YouTube and Instagram, you are looking at a value of $12.5B. Considering we are less than 1/8 that value now, it puts the price of STEEM at $51.
This really shows the huge upside in STEEM. If conservative estimates of dtube and Appics brings STEEM to $50+, just imagine what the aggressive targets look at. Granted, these 2 apps should encapsulate the majority of the value, there could be many more uses for the STEEM blockchain that we haven't even thought of yet.
The potential is definitely there. The question is how quickly it will take the masses to start adopting. No ads while getting rewarded for social media?! Sounds like a no brainer to me!
