I need a script/cron job that will calculate a "profitability quotient" based off of coin price (from bittrex api), block size, and current difficulty.
If you can do this i will pay fairly
Know the formula? Its about 2 days work

$hashTime = ((float) $difficulty) * (pow(2.0, 32) / ($hashRate * 1000.0)) ;
$blocksPerDay = (24.0 * 3600.0) / $hashTime ;
$coinsPerDay = $blockCoins * $blocksPerDay;
$revenuePerDay = $coinsPerDay * $conversionRate;
