P.S. Please, don't ask me is this a lie, is this a scam.
Warning to Heavycoin users: this is extremely unlikely and to the best of our knowledge not possible. Seems pretty sketchy looking too. As always, exercise extreme caution.
You probably already know that the total HVC net hashrate is not only from "botnets".
If there are any botnets, they must be a reasonable minority of the hash rate. You can see this by taking the total hash rate (
http://heavychain.info) and subtracting the hash rate of the known cpuminer pools.
