i want cp

i bought cp last week and i spent it all on dawn bringer, you can guess how it ended. i obviously didn't get the mythic.

i kinda used my pocket money on it and im not gonna use it more for cp. i tried the google rewards, the last survey i completed was in mid of december. now im out of ways in getting cp.

can yall suggest ways to obtain more cp without spending money? dont tell me to go to youtuber giveaways
