hey guys.
I've hired one php coder for mining profit calculator code.
but here got a problem from difficulty increment factor.
When a difficulty increment factor exists like every 14 days the difficulty getting increased 10% around, the earned BTC should be decreased as time goes by, then the BTC earning graph looks like curve,
but my existing code, it shows a exponentially increased BTC earning.
Can someone help me to fix this code ?
$DifficultIncrementPer value is % one, it used to re-calculate the difficulty of next 14days as my code is shown below
$Difficulty = (isset($_REQUEST['difficulty']) ? $_REQUEST['difficulty'] : '');
$HashRate = (isset($_REQUEST['hash_rate']) ? $_REQUEST['hash_rate'] : '500');
$TimeFrame = (isset($_REQUEST['time_frame']) ? $_REQUEST['time_frame'] : '30'); // user input timeFrame
$DifficultIncrementPer = (isset($_REQUEST['diff_increment']) ? $_REQUEST['diff_increment'] : '8'); // % per every two weeks
$HashRate = ($HashRate * pow(10,6)); //mhash
$TimeArray = array($TimeFrame,"1","30","180","365"); // user timeframe, default timeframe (1, 30, 180, 365)
$SecforBlockCurrentDiff = $Difficulty * pow(2,32) / $HashRate;
$SecforBlockNext14dayDiff = (($Difficulty*(100+$DifficultIncrementPer)/100) * pow(2,32) / $HashRate);
if($TimeArray[$k] <= 14)
{
$BTCEarnedPrev = round((($TimeArray[$k]*25)*(60*60*24)/$SecforBlockCurrentDiff),8); // 24hours based BTC
}
else
{
$CalcTimeFrameContent = floor(($TimeArray[$k]-14) / 14);
$BalanceTimeFrame = $TimeArray[$k] - (($CalcTimeFrameContent*14)+14);
$BTCEarnedPrev = ((14*25)*(60*60*24)/$SecforBlockCurrentDiff);
for($i=1;$i <= $CalcTimeFrameContent;$i++){
$BTCEarnedPrev += ((14*$i*25)*(60*60*24)/$SecforBlockNext14dayDiff);
}
if($BalanceTimeFrame >= 1){
$BTCEarnedPrev += (($BalanceTimeFrame*25)*(60*60*24)/$SecforBlockNext14dayDiff);
}
}
