$1000 in 5 years seem to be a stretch. But I do think if the adoption for the website grows at the current rate then it might reach $4 by the end of this year at-least.

If any one of these platforms challenge their counterparts, it will unlock the real value of Steem. Eg : If Dtube can really take off, people start looking at it even as a second viable option that would create enough attention and people will flock to buy Steem. Until then we have to be patient :)
