I wonder how a drop or a jump that is not "man made" but natural would look in your opinion.
How could anything related to a market that is, despite its bots and trading algorithms, still completely run by humans who make the decisions how and when and where to trade and at what prices?

Yes, it was just as man-made as the jump from 30k to 52k, the fact that you want to categorize that one as natural and this one as some evil forces forcing against you is simply subjective.
