Whales watch each other, it just does not happen, this "insider trading". I will let you know if I see anything suspicious, feel free to let me know if you see something. Btw Yobit trading is insignificant at the moment, don't waste your time watching those trades.
How are you watching each other? Do you know everyone's wallet addresses?
The Whales even know the wallet address for the Shark Node.. A Whale created a program that provides me data on the Network and my own masternode. Soon there will be a version that can monitor your mastenode..
