ONCE AGAIN AND A LITTLE SLOWER .... (sorry no pictures)
mining $2 per BTC @ 1M difficulty is the same as mining $20 per BTC @ 10M difficulty.
You have a point on VOLATILITY but that isn't the same as saying BTC is dead @ $2.00 or $x.00. The best thing ever for BTC in the short term would be for it to hit $2.00 and VOLATILITY collapse. That would massively increase adoption. BTC @ $2.00 w/ 1% daily volatilty is better for everyone except specualtors. BTC @ $20.00 w/ 30% daily volatility only benefits speculators. Yes you can mine and profit less @ $20 BTC than @ $2.00 BTC.
You say again like that's what you said the first time...
Slowly for you:
Mining $2 per BTC @ 1.7M difficulty is like scouring the roadside for aluminum cans to return, except imagine every day the cans are worth a little less.
