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.
