I would gamble at 2 coins, I dont trust calculators, They are not aware of the 12 PH coming online over the next month, It will be lucky to make back 2, But that is my opinion ONLY.
Is that a bid of 2 coins? Or just an opinion?
Also my odds were calculated with a consistent difficulty increase of 24.7% per jump, which is definitely on the worst case scenario end of the spectrum.
