Manipulation or shall we go even lower?

Strange movies were in online yesterday. Before the cue ball began to fall down, there was a transfer of 2,300 BTC to the Kraken exchange, which may have triggered the first downward impulse on the fear of possible sales of this bundle. And then we have already connected the stops of participants who entered the breakdown of the 61500 level and we saw a cascade of sales, stops and liquidations.

As a result, BTC is below 60k again. But what was it? Manipulation to collect stops or real sales by large participants? 

Literally an hour later, 2k BTC was withdrawn back from the Kraken exchange. The conclusion is obvious: what was this translation for? 

Collect stops, fill your orders? To cause more panic in the market?

There is such a possibility. And if this was really a manipulation, then we must quickly buy back the current drop.
