any one know how to do the math on , at what price does btc have to drop to ,to have 0.00 divdends. a rough estimate will work too.
Your question doesn't make sense. Dividends are not a function of BTC price.
You probably are asking what difficulty. I don't know, but you can probably figure that double the difficulty is 1/2 the dividend. So if the dividend is ~1000 satoshis would be less ~ 0 after 11 doublings. So 140 PH/s * 2048 ==> ~ 280 EH/s. (1000 PH/s = 1 EH/s)
i meant , if btc drops too low , the coins mine would not be able to cover the hosting/power cost or what not. im assuming they trade the coins in for cash to pay the upkeep. what price would it have to fall to make the dividends be at zero.
My guess is it wouldn't have to be quite as much as people think. Somewhere around $325-350ish range would be my guess. Based on a rough guesses as to the power consumption for the hardware he's running and it's efficiency. Since his hosting and electric fee's will continue to be the same from here on out it appears :/
So, with all these fixed costs, at some point we'll have to shut down the mine until the bitcoin price makes it profitable again! I wonder if that will be sooner rather than later!
I really doubt it will ever get that low but who really knows. With all the negative stuff (gox, bitlicense, scammy securite operations) along with all the good (wider acceptance, btc atm's, vendor adoption, etc.) it's hard to tell whether bitcoin might actually drop that low again. I suppose it's possible but I'm still hoping unlikely at this point. Regarding Cryptx shutting down, naw, he will simply pawn off his less efficient hardware by then to some other unsuspecting suckers that haven't run the #'s and then buy newer and more efficient gear with it (I presume). Worse comes to worse hell he can just run another IPO (yeah, this is sarcasm but I wouldn't be surprised if something like this did happen). Not much would surprise me in this crypto security game at this point :/
