Ok im at 20kcs, can change 15 credits for 27m, im willin to put some money in but whats my fastest n cheapest way to go bout it?
You honestly would be spending thousands of real $$$ if you go that route for the best stats you can... not worth it.
Farm, volley, then farm again. For me, the only time you buy the money that the nurse offers is when your t5 lcbc. That way, you'll get more money.
