GPT sites tip of the day #5

You can double your earnings from Get-paid-to sites, by using promo codes or bonus codes. Popular GPT sites like Freecash and Cointiply often release promo codes on their socials. You can also find some old promo codes that you missed by searching online. 

Cointiply promo codes work until they are valid. You can even redeem a promo code released years ago if you haven't redeemed it before. You can redeem Freecash promo codes only after you reach level 5. Some codes even require level 10 or level 15.
