Correct.  And ALL of those could have been sold in November.  Or in March. Or spread evenly every day between November and March. Or any other possible arrangement of sell orders and any number of exchanges.

The OP is making sensationalist claims that these bitcoins were specifically sold in specific amounts on dates when the market took a significant dip.  He is claiming that the dip is directly because of the selling of those bitcoins.

I've seen no believable evidence that the OP's claims are anything more than his own wild imagination.
