Can some one explain to me how mining will not eat all BTC value. Eg any value left on the table will make mining profitable to the point of BTC value.
There is no guarantee that mining is profitable. For many miners, it is not profitable.
but then does not mining ultimately consume all value of BTC?
?
or whatever value it leaves on the table.
Eg say BTC is more efficient with mining that FIAT which is expensive to maintain handle make, use, dispose and for banks to maintain that system.
The
FIAT - difference Value = cost mining(t) = the amount at (t) left on the table so to speak.
sure some miners will over estimate this value and go broke. My larger concern is that the mining must ultiamtely consume entire value difference as long as it leaves the money on the table.
This makes me think that POS will prevail as mining is near zero cost, just a node maintain, or some other non mining way. Even say POS has issues, they are software and can be sorted.
There seems to eb no way to get around the mining issue in a system geared for mining.
I am not saying BTC will nto go to 10K or 100K I think it will, but its sort of like pushing against a massive head wind
You're making an error in assuming mining profitability relates to BTC price or its viability, I think. There can be value on the table by miners shutting their units off. This slightly decreases security of network as a whole, but not by some shocking margin which'd affect price, only the bottom line of miners still operating -- miners can make mining profitable for others by shutting off their rigs if they so choose, or they can move their rigs to a location where electricity is cheaper - but it's not really relevant to Bitcoin as a whole. There was a concern when ASICs were first coming off the line that the insecurity of not having many different people running ASICs could leave BTC vulnerable, but we managed to get out of that unscathed and the issue where someone could swoop in with a $M or so and take over the vast majority of the network's mining power passed.
Mining is fairly irrelevant to BTC market, and becoming increasingly so. At next halving, mining impact will be minimal, while it becomes nearly non-existent in halving, further diminished by increasing number of coins in circulation.
You should think of mining as an industry completely separated from Bitcoin, so long as the number of miners are able to reasonably secure Bitcoin, which they currently are (though it's been a while since I've seen revised numbers on the cost to manufacture enough ASICs at cost to control vast majority of network). Though, as BurtW will tell you, controlling majority of mining power isn't some Bitcoin-ending catastrophe, but it's a problem which is monitored nonetheless and'd be discussed if it became a concern again (ignoring similar but different GHash issue).
