Difficulty is up another ~15% in eight days , Not sure if it is worth it to invest in ANY new hardware at the current hardware prices . Even with a coupon and discounts a SP35 or 31 costs over 3k with shipping
ROI is looking somewhat impossible because by October when units ship difficulty could be up 30% from now ugh.
Don't worry. It will drop down to about 5-7% just few days before next difficulty change ;-)
As always fine work with your charts and hardware predictions. You've saved a lot of investors more money and grief than you'll ever know. As you say "Pay it forward" I just want to say thank you again for paying it forward.
