I think this is an old thread trying to attract people to sell bitcoins so that they can buy bitcoins to make a good profit if the price of bitcoin will increase again back..
This is just like in trading section that they are saying that there is a big crash so people will sell their holding coins after that the price will redice and they will buy for cheap price so that they can make a profit if the price will increase again back,,
I think you're right and I find it funny that a lot of whales in the exchanges try to do this non-sense also. The sad thing is that people are super susceptible to hearsay and actually listen to this sort of thing. You should take a look at the trollbox on the Poloniex exchange, hilarious stuff in there.
