I don’t quite understand this relationship. When gold miners halt production, no gold is mined. But with Bitcoin, isn’t a new block mined every ~10 minutes regardless of the amount of active miners? I.e., isn’t production relatively constant?
Discussion
the difficulty gets decreased
But adjusted so that the fresh supply remains constant, right? 3.125 every 10 minutes on average?
correct
I think the point is…
Hash rate = fn (BTCprice, ElectricCost, MiningRigCost)
I don’t know what that formula is but in general terms examples are…
BTC price goes up - more miners join in
Electric cost goes up - miners shut down or move
Mining rigs are cheaper to buy - new miners join the fray.
There will be a momentum factor in the formula: eg: miners don’t go bust overnight but can run on reserves for a while, it takes a while for new mining rigs to reach market, etc
Ps. difficulty = fn(hash rate)
I might be a little slow here, but why does this mean that the production cost can serve as a floor for price?
My thoughts on this…
If the miners have enough financial reserves - and that’s the big if - they will not sell to the market below their production cost. They will hold for as long as they need/can. Miners holding back their production will *possibly* cause a shortage of supply and stop the price taking any further: a price floor.
