Heyo! It takes me about a year and 5 months to get to 200k as a f2p but with ninja assist feature and more power features here that it wasn't there at the beginning of the game, you can get to 200k faster than I did in 17 months and make sure you play smart. If you can do that, surely you can make it in no time! :) I gained 100k in less than 9 months from my post this year as 200k to 300k thanks to amazing ninja assist~
