Already have pm offers for max cash in game 2147m vs the 99, need better.
You should probably take that offer, its taken people like a week of grinding no sleep, eating fast food slop, to get to 99 using the Crystal Extractor.
That extractor is going to be Nerfed next week, eliminating a solid extra 30,000 XP an hour, making the grind to take over a week of 18 hours a day sweaty effort.
