Consider what happens in 13 weeks then ;)
It's called black friday sale tiiimeee (~‾▿‾)~

If exchanges need more liquid steem, the price must go up, or exchanges will lose their reputation due to stalling. Then, 13 weeks later, "that" pool of steem will be free to be sold, and quite probably it will be sold = price dump..

Sounds like a nice moment to invest now, sell when it's high, before 13th week, then buy back after the dump..

But it's not that simple.. power down ends on 13th week, but provides steady stream of steem through all the period. So there won't be any huge rise and huge dump. Maybe small but noticeable rise in the beginning, and then slowly steady falling back to normal..
