Why? This makes no sense
Difficulty can vary if the price vary, if bitcoins is worth 1$ then a lot of miners will stop mining cause they will not be able to pay the electricity, if bitcoin jump at 50$ then a lot of miners will join and mine more
But difficulty do not influence price. Price influence difficulty.
This seems hard for everyone to wrap their heads around. Okay. Every month let's say 200 new pounds of gold is mined. In September, the average cost of mining gold was $10,000 a pound. However, in October, a new mine is discovered that prompts the old mine to close because it is much easier to mine from. Now, it costs $2,000 per pound, and 200 new pounds of gold are also mined. This cheap new gold is announced on the news in the beginning of October. If it just because five times easier to acquire gold by the company who is mining it and the investor knows this, why should the investor pay the same amount for gold as they had been when mining gold was harder? Worse yet, what if a competitor finds a similar mine? Competition would naturally bottom the price out, even if output was the same.
Diminished manufacturing costs cause the same economic behaviour as enhanced production amounts for the same cost to the company as before because they change the cost per unit of output.
This I think is actually an economic flaw of bitcoin; if difficulty never decreased (as happens with actual valuable commodities such as gold and oil) the price would have to stay high because the cost as a function of difficulty would only go up or plateau as time went on. In real life, the price of a barrel of oil does lower with demand, however, the ease at which oil is obtained still remains at relatively the same difficulty because the supplies on Earth are exhaustible.
The intrinsic value of bitcoin I believe is strongly tied to the difficulty in obtaining it, and if it becomes less difficult, naturally the price would have to go down. It's similar almost to LCD TVs; even if the demand for LCD televisions is staying at roughly the same levels, competitively the price has been driven down over the past decade because the process by which they are manufactured has become cheaper. The equivalent scenario in bitcoin is that the cost of manufacturing bitcoin has become cheaper, so people, obtaining more for the same hash rate if they are mining, will be more willing to sell the bitcoin for less in a competitive market. I think it might be possible for this to lead to the collapse of the bitcoin market.
This is pretty text book economics stuff, but I could have it wrong. I was right so far about the equilibrium being around $4-6 USD for the current difficulty level and I fear I could be right about this, too (I am a miner and making money, but admittedly the returns for the past 6 months were nothing short of insane for miners).
"But difficulty do not influence price. Price influence difficulty." This statement is flawed because both variables are functions of each other; that is, difficulty can be modulated by changing prices or price can be pushed in either direction by changing difficulty
so long as the difficulty can go back down. If the cost of production were to stay the same or only go higher, it's much more likely that the prices people are willing to sell their bitcoin for will be higher. Buyers, knowing the costs of production, will also be more likely to spend more for them since they would not be able to so easily acquire them for themselves by mining.
