It would probably be better if the developers were the manipulators if you trusted them to only use manipulation to support the price and not to wreck the coin.
I explained at the following link that if your developers don't manipulate, then a whale can buy cheap as the token flounders:
https://bitcointalk.org/index.php?topic=1413819.msg15400907#msg15400907So who is the manipulator of NEM? Who acquired most of the tokens?
They seem like such a scam , I have been ignoring them.
But if anyone knows the 1st exchange to increase in Price it might point toward someone.
Example:
BTC38 XEM/CNY $ 2,303,970 $ 0.012163
If it started on BTC38 , then the Chinese are behind the Pump.
If it started on Poloniex , then the American Pumpers, possibility Goldman Sachs.
