dammn nigga i just sold before panic selling. Any explanation why this bug?
If you sold before the dump, then that is good, because you can buy back at a lower price, but if you sold during the process of the dumping (or near the low price point hoping for a lower low), then you may need to take a loss and buy back before the price get's too far above your sell point. On the other hand, you could take a chance and wait it out, which may or may not pay out (despite being a bit stressful to wait out and hope for another dump, which is not out of the question at this point).

I am lucky noob

You bought back, or not yet?
I usually like to stagger my bets rather than to attempt to play too many BTC all at once.. and accordingly, if I were to sell 4BTC all at once, that better fucking mean that I have at least 200 BTC in my portfolio or otherwise I am pretty confident that we are going to experience at least a 10% correction, and I would be buying back every 2% or so, once the correction stabilizes.
I also think that it is safer to sell on the way up and buy on the way down rather than selling on the way down (even though once in a while you could get lucky to attempt to time such).
No, this is all I have. Yes, noobish, I shouldn't trade with all my money but hey... let me tell you something

.
I follow China charts, because EU charts are lagging around 5 second after chinas. (Euro has the smallest volume of BTC, CNY the biggest).
