Its not manipulation just plain old dumping.
The scammer got his millions of chesscoins from dev for nothing and then dumped on yobit without caring for the price to recover. Sad but true
Agreed there, although I wouldn't rule out manipulation later on, as the dev will be holding an awful lot of chesscoin.
Which brings me to my next point... how many coins does he have, exactly? We can say all of them, but all of them - coins sold. How many did he sell?
If I was the cynical sort, it wouldn't involve a lot of detective work to figure how who this mysterious 'secret man' is, who is dumping on yobit with a seemingly endless supply of coins.
By the way, anyone else find the timing of the bela rate swap change a tad peculiar? Some have described changing the rate as bad judgement, but it makes perfect sense when you think about it. Yobit volume of course increased after the rate change, as otherwise folks would just do the bela swap at 10x rate. Get rid of that advantage, and folks instead buy off exchange. That is an advantage to someone.
