Challenge method in justplay
Kung may nakita po kayong nagpopost sa justplay na offerwall lang ang effective, wag kayo maniwala dun. Using my iphone, this is my total earnings after 9 days (may 29-today) by doing challenges. 70-100 ads downloaded per challenge = 200-300 pesos. dagdag mo pa yung makukuha mong coins while doing the challenge.
Sa android naman ang ginagawa ko is I spend 1 hour and 40 minutes on challenge which nakakadownload ako ng 60-80 ads and nakakkauha ako 100-110 pesos. After that dinedelete ko and download ulit. Wait 3 hours for challenges to appear then repeat lang. 400 per day ang nakukuha ko sa android (hiwalay pa yan dyan sa total earnings sa image dahil sa iphone ko lang yan). Ang downside lang sa method na to ay ang face verication, kaya risky din to gawin. Ginagawa ko lang to dahil ayaw ko mag hintay ng 12 hours para mag reset ang challenge. It's up to you kung gagayahin mo.
Edit: USE SEPARATE PAYPAL if you're gonna use multiple accounts and delete the downloaded ads after you got your money
