well he has re rented now for a week now and last look his hashrate was 21ghs out of a antminer! anyway to determine what coin is being mined?
do mining exploits exist? im pretty sure this guy has mutiple rigs rented so he has to be making a profit.
If you are renting your rig out on the Leaserig proxy, you can't know what pool it is.
If you are using the API, you can look at the pool and its coin.
