When did you post this because it is nowhere near Polly? I've seen these Post in these threads all week long and the fact is that there are very small discrepancies and very small drops there's nothing anywhere near what would what would be considered a drop. I don't know where everybody's getting their information from because it is holding steady at 4,000 with very small drops.
Well Bitcoin didn't have such discrepancy the last few months since the last Fork/Segwit. I mean yeah I also think that it is not kinda of thing that can be considered as a 'drop' but hey, the banning of China did cause a ripple effect in the price for the past few weeks. But then again it is not a major problem, though I also think that it made the progress of rising the Bitcoin's price resulted a halt, we it drags a little of it if you know what I mean.
