Hello once again, so i made a new account to upload a different niche but want to get some subs before doing it, I know of AMF but it seems slow even when i have the CPC at 9. I'm Currently getting around 150 with YouLikeHits (premium) Since i make 2k Credits an hour, but i need atleast 500 subs a day if i want to start uploading next week, please link me some exchange sites below. Thanks!
