Definitely for some time it may have stopped, I have seen its market value lingering around $4100 to around $4200 lately, and seems to have settled there. I think there is a resistance line somewhere there, and psychologically people don't really want it to rise too far above that. However, I think that price barrier will be broken soon sometime after the 25th Oct hardfork of Bitcoin Gold, and it will start its bullish trend again.
