I see ~93% of the volume is on Poloniex and Kraken:
http://coinmarketcap.com/currencies/ethereum/#marketsDoes anyone know if these exchanges enforce strict KYC and keep records of all trades so that authorities will be able to determine who was selling to whom? So an investigation could determine if the insiders were buying from themselves to manipulate the price?
Afaik, this would be insider trading and should get them jail time (at least afaik according to SEC regulations).
The fools who support these scams by buying the coins and promoting them, are giving the government every reason to regulate alt-coins. You are polluting the well from which we all drink.
In Poloniex I am pretty sure I have seen some strange things.
In the LENDING section, I have seen automatic compilation of a great amount of prices: they did it to lower the price for lending money.
I have seen appearing like 30-50 new offers with slightly different % and low amounts at low % fee.
Then they disappeared and after some time reappeared.
I cannot tell if that was from Poloniex itself though, or from a user, but I don't think a user can submit so much data in a single second, unless they have some kind of automated program to do it. Is there anything similar for Poloniex?
