The image details exactly how my (AntS5) profit has declined over the past 70 days.

My starting daily payout was 0.7341805919% of my principal.

My current daily payout is 0.1171920740751260% of my principal.

My average daily payout declines -1.332518616% every day.

If this rate of decline remains stable, I will only make back 34.9358556% of my principal.

In other words, at this rate I will never make my money back and instead I will lose 65.0641444% of my investment.

The two key factors contributing to payout decline are difficulty increase and BTC/USD denominated fees.
