It will reach 200 very fast, don't have to worry about that, but it will go much lower, i don't think it's smart to buy back at 200 already, try 180 or even around 50. 180 is possible but im unsure if we will stabilize or have a dead cat bounce there of which you can profit.
And what does lead to you this ending? I don't see any huge drop and i don't think we will go below 240, only if big dump would happen (stollen coins or something along this) then i would think about that scenario but i don't see anything like that anywhere near.
