I just don't get why people think there should be zero profit for mining. I agree it shouldn't be a huge profit, but break-even mining removes the incentive to secure the network.
The incentive is to ensure that the transactions you send to others and perhaps more importantly, those you are receiving, are processed quickly, correctly, and efficiently. That is the only incentive required in my view. In the future, most of the mining will be done by those with the greatest vested interest in the system itself - i.e those with profitable businesses that require the bitcoin system to function efficiently as a means of payment.
They won't care about mining at break-even, or even at a loss, when they are making plenty of profit from their individual bitcoin enterprises. Do you think banks and huge corporations require their computer and telecommunication systems to have zero depreciation, or indeed
appreciation? They count these expenses as operating costs, and bitcoin mining will be no different.
Would you (or anyone else for that matter) work to only be able to pay for the gas used to get you there? What would be the point?
No I wouldn't. But if traveling there and back was the only work I actually had to do, and if I had no other obligations, I may just go along for the ride. If I liked driving enough, I'd be more than willing for someone else to pay for my pastime. I might even net a few bucks if I could find a gas station selling cheap fuel. At least until I realized what a waste of resources the whole venture was, and started to feel a bit guilty about the environment.
These are valid points. However, There is plenty of work involved in maintaining and to a lesser extent operating mining rigs/farms as pointed out by Crypt-Current. But, to
expect people to mine for zero profit out of the kindness of their hearts, so others with zero costs can send a tx at THIS early stage in the project just dumbfounds me. Don't get me wrong, I mined for 6 weeks at a loss because it's what I do, and I don't have a problem with the small loss. I make far more from trading anyway. The same mindset would be the example of the business that relies on their own mining efforts to send and receive tx. Most others right now aren't so generous though.
Difficulty is what balances the profits. When price rises, difficulty is sure to follow. So, profits are driven down. When profit drops below comfort level, miners will start to drop out.
If they continue to make a small profit, the difficulty will remain high enough to keep massive profits in check, while still being worth the time to mine.
I'm not trying to troll you. I have just read so many posts of "Miners shouldn't make any money". It's kind of aggravating, and I am done now.
