Why would someone use an exchange to shift $1.2 Billion worth of bitcoins?

I cannot validate or verify the data that was published or posted on Reddit.com, because I had no alternative source for the information. So pardon me if I posted something that cannot be verified, because I hope the discussion would lead to some more investigation from other people to get to the root of this dump. 

We will have false reporting and we will have people spreading false information, but we should still continue following up on all the leads to see if we can find out what triggered this dump.

It is not natural for a dump to occur, if there are zero bad news that triggered this event.

The story could be false, but that's not saying it cannot be true, but whichever it is, the truth is that the bitcoin price has been falling for some days now, and its peculiar with enthusiasts to bring up possible reasons for that, even when they are not true.

We'll have to wait a couple of days to ascertain the veracity of this news, to be sure it's not just someone there trying to out the blame on bitcoin whales, even if the news be a rumour it could also be negative towards the bitcoin, especially for the new enthusiasts in the system through the introduction of Bakkt.

I believe I read an article which stated that a whale had moved about a billion worth of Bitcoins and we all know that when things like this happens, it tends to bring chaos,  I am sure that a lot of investors saw it and hurriedly started selling their cryptos which has contributed to the recent fall in prices, I believe this to be very deliberate.
