Some of the strategies I've seen is to reinvest for the first 190 days and after that, you withdraw every other day while reinvesting. I understand that the break even point changes with difficulty but I do believe Bitcoin will be worth 5x as much by the end of the year so it should make up for it at the end.
I'm currently in the AP pool and I've seen spreadsheets that show which mining pool is currently gaining the most. It switches between ap and the f2 for the most gains, but im going to just keep it at AP for now.
