Yep, really. People that say it isn't do not know, it is only their opinion based on history. When you cashout please post here to prove it is legit.

Mining machines are graded in basically 2 ways:

1 - Hashpower. For BTC this is measured in Gigahashes (GHash). There are many MANY machines, but for example, a USB miner might have a hash rate of 2GH. This is what determines how many coins it will earn over time.

2 - Power usage. This is measured in Watts (W) and is a measure of how much electricity your machine pulls from the wall. The higher the number, the more you pay in electricity costs, and often the hotter the hardware runs (meaning a possible extra cost to keep it cool).

So a miner would be looking for the highest hash power for the lowest power usage possible, also taking into account the cost of buying the equipment. It gets complicated

Hope that helps a bit.
