I'm not going to go digging, but you recently were arguing in this thread that bitfury doesn't sell their coins, they're banking on the future, being positive on today's income sheet is secondary. They are using big venture capital money to basically buy huge amounts of coin without pushing the secondary market. This is absolutely forward looking, not investing in today's system that costs $7 or whatever per tx in inflation costs.
Your final statement should stand alone as it succinctly shows your complete misunderstanding of how, and why(!), this whole thing even works.
Hmm wait a minute. Who ever mentioned fiat profit?
Profit, in this case, is denominated in Bitcoin. Bitfury mines the Bitcoin blockchain simply because it is the most valuable coin. The value is not in the future but now. The fact that it fluctuates is irrelevant.
As for your last comment, what is it you don't agree with? Do you propose miners are origins of Bitcoin value? Or that we should set the rules of the protocol so as to maximize their profits regardless of the costs externalized to other participants?
I know you're quite enamored with bitcoin, I am too, but the real world (power companies, sellers/renters of real estate) tend to still be using that whole silly fiat thing. Haven't quite listed themselves on MPEx with the other titans of industry, as it were. The world isn't our own personal castle game... yet.
Miners incentives are the variable that counts. And it isn't gmaxwell in a cape that is keeping them in line and holding their arm back from slaughtering the golden goose. Why? Because satoshi designed the entire system so that their interests were sufficiently aligned with those that they service.
Yes, I agree he was very wise in retrospect to set the block size cap.
In fact I will suggest he did not even fully understand the importance and critical importance of this decision for the long term success of Bitcoin. Absent of a cap the incentives you refer to become completely skewed in favor of the miners at great cost for the security & decentralization of the network.
Don't get me wrong, we shall increase the block size eventually, "just not tonight, dear".
