It took me less than 48H to activate monetization on a new YouTube channel using this.
Step 1: Sign up on this site: https://www.ytmonster.net/
Optional: Referral (This one is the referral: it gives you a 15% bonus + 2000 extra credits)
Step 2: Start a client and earn credits, which takes less than 10 mins with the bonus credits you have!
Happy learning!
