If the message is true, and it could be true. This will pretty much crash the market for ETC.
Chandler Guo, an owner of 98Gh/s hashrate for ETH announced that he is going to protest Poloniex's decision to support ETC. By that, he is going to send all this hash-power on the ETH network, meaning, he will probably succeed in making an 51% attack.
I really don't know the real full effect that this could cause to the network, but I doubt it will be good.
So if your going to invest in ETC, take a look into this and make your own decisions.
This is just a friendly warning!
