Ahh, didn't see dedicated, yeah you are probably fine then.
Still doubt it will be worth it, especially since you are paying gas. I haven't looked at how much it will cost in gas though, so who knows.
I don't get why the mining isn't on their own chain when they get it running.
Yeah, not sure if it will worth it but I didn't rent these servers just for the purpose of mining, they're doing different things already and have some CPU power. Why not :)
It comes down to how much that gas is going to cost you. Gas isn't cheap and it tends to spike often throughout the day.
