The road to 50$ STEEM is through attracting 1-10k different communities who through holding 10-100k SP can power a user experience on their own website(s) that they cannot accomplish without Steem. Those may sound like high numbers, but they're really not. If we keeping asking "how can we provide a dedicated community willing to make that investment with the most power and the best tools to achieve their own goals", then I'm sure we can get there.
man... $50 is quite ambitious. I am not against it at all I would be relatively rich...
But it is very possible we can be on an S curve and not even know it... if we get just 500 communities or apps or whatever who want 1 million steem power (or equivalent in delegation) then there wouldn't be enough steem power to go around... could get interesting if steem gets adopted to the point the price spikes up due to demand and/or low circulating supply.... I have a gut feeling steem price will TAKE OFF once steemit and ned have exhausted all of their holdings.... weird gut feeling... we shall see
