And, lets not forget, YAC's dev, flipped a switch, and disappeared. I'm sure he dumped what he had, at its high debut price, and laughed his way to the bank.
The blockchain disagrees.
http://yacexplorer.tk/address/Y7oPoonGNZnqCfTjRirZkNvVusvHcqc7xB <- mined the first 6 blocks, untouched balance
http://yacexplorer.tk/address/YBJeQQFCipbC4LrZTnTu6j5rSAMsqRkGJb <- humongous untouched balance, block 7 and other early blocks ended up here.
Personally suspect the dev is one of the people involved in the ongoing development, however, have no proof, don't give a shit, and figure they will never "out" themselves anyway.
