What's interesting is days destroyed is basically at zero. All the coins being moved to exchanges to be sold are probably very new. The theory Chinese miners are selling to get their money offshore denominated in USD is pretty interesting. I will keep coming back to BurtW's post on mining breakeven costs based around energy, which projects a mid October price of $233. If miner's are selling there comes a price point where buying is more cost effective than mining. I could see a bottom around $250. When calculated in the OP over the time period from March 14, 2013 to March 13, 2014 the average increase in the difficulty and hash rate was 23.92% per adjustment period and the average length of each adjustment period was 11.38 days. Recalculated over the period June 29, 2013 to June 29, 2014 it was 23.45% and 11.41 days. Now, recalculating over the period August 24, 2013 to August 31, 2014 it is 21.12% and 11.63 days. Assuming the network growth rate over the next year is the same as it was this last year we get: Hash Rate Power Energy Cost Cost

One problem I have with this is the assumption that big miners are in it for BTC and not fiat. I don't know everyone's motives but I am sure that for some it is an opportunistic business model (ie buy ASIC's, mine, sell, profit). As such what gives is price and it's a race to the bottom in terms of who has the cheapest electricity. Hardware is a sunk cost now, so it makes sense to continue to mine as long as your electicity costs less than than you can sell the BTC for, even if that means just minimising losses (on sunk costs), for all those miners whose goal is not to accumulate BTC. We hear many times that miners will just hoard or switch off and buy instead. IMO only those that are true believers and not in it for fiat will do so. The rest will get what they can out of their equipment while they can. Many a bad investment decision has been made in the past and will be in the future in many industries. Why this mythical illusion that BTC is so different? It looks very much like mining bubble to me EDIT : In conclusion is it not a perfectly reasonable proposition that difficulty could nosedive to match current price as inefficient miners who are in it for fiat simply switch off their hardware at some point and exit the game or wait for their equipment to become profitable again, if ever? The assumption that they will simply buy BTC instead seems deeply flawed. Meanwhile the BTC inflation rate (supply) will remain constant. In the absence of new demand where does price go ? I agree that the idea that miners 'start buying' is deeply flawed but when mining becomes unprofitable they will stop mining, supply will be reduced and the price will stabilise. Is this not part of the big "Satoshi Plan" of checks and balances for the functioning of BTC anyway; at the moment we have a confluence of negative factors: too much supply and negative sentiment due to Gox, Neo et al. When the miners stop the flow of coins the price will find equilibrium and sentiment will return with a stable price. Simples. |
