I have no clue what it is, but I am 100% sure it is the reason why the Ethereum network is bery slow at the moment. I need to pay 50 Gwei in order to have a normal speed transaction. Even with that Etherdelta is giving errors.
You are right, this game devours 15% of the ether network, and already as the second day the ether network got up. I can not imagine if we allow several such projects to be launched simultaneously, we will bury the ether forever.
Mean the project make etherium very slow? Oh my good. 50 gwei? Such bad idea to increase become 50 gwei.
I think this happen in last 3 days. It happen to my transaction in etherdelta and in myetherwallet.
