They can and will. Mark my words, the dev will dump and kill this coin. I have 4x R9 290s, 1 280x, and 2x 270s churning on this full time and I got 5 coins in 36 hours. This is why premine doesn't work -- it fundamentally fucks the value of the coin so that it's not longer tied to the amount of energy required to create it.
Can we mark your words by observing you leave the folding pool?
Logically, if you are sure the dev will dump and kill this coin, then you should exit your 400,000 ppd out of the pool. The other 80,000,000 ppd will continue on.
Thanks for your contribution.
