I am debating between selling at the current price or waiting till the next difficult increase.

The next difficult increase is in about 7 days and it is predicted to be an increase of 18%.
A few day ago the predicted difficulty increase was 45% and 77% a few days prior to that.

The reduction in difficulty increase tells me that miners are starting to leave because of the price drop and because they can sell their cards for a ridiculous price right now.
You can find used 58xx and 69xx cards for sale but they are expensive.

I am leaning towards selling at the current price.

What is everybody's thought on the matter?
