The CC world is the only place that I can think of where no one has to lose. We create money from nothing, we give the blueprints to anyone free, yet people are stealing money left, right, and center (everywhere you turn).
We should have a million billionaires by now but instead equity has dried up 70%.
Mining costs money.
Mining costs are mining cost, they are not currency creation costs.
The research and development that went into the creation of the currency cost money however ALL of those costs are so negligible its not worth discussion, never the less it was the creator's cost NOT our cost, the scheme was given to us free.
Gold, silver, diamonds, oil, and any other natural commodity that could be used as a currency was created by God (at his cost) and given to us FREE, the mining we use to remove it from where it is to where we want it to be is not part of the creation process, its part of the extraction / transfer process.
Notwithstanding, depending on the type of mining you are doing it could actually have multiple uses. For example, your mining could actually solve PRACTICAL mathematical, or scientific problems this way the more you mine the closer we, as a society, get to solving REAL problems. See 'Gridcoin' and 'folding coin' for more details on that.
