it has been over a year since OP made that specuation and there is no indication of any kind of stabilization for bitcoin price. it has been in $200 range and couldn't go lower and it has been rising ever since!
Well, they thought that price would "stabilize around $150-$200
for the next 8 months to a year." The price might not have reached $150, but it sure seemed pretty stable for the 8 months after their post: volatility was low, and price was range-bound from late January 2015 to October.
Bitcoin was for a long time stable and many people dont like it of course because the value was not that high now so they cant sell it with profit and that is bad for them.
But it will rise soon because the halving is also coming and the it kept also stable for a long time so it will be now the time to rise and make profit.
