Preferably, use only personal PC to login or register in your accounts;
99% from PTCs sites are scam. Don`t register everyday when appear a new PTC;
Before you register on a PTC, visit their forum;
Any site, which has no forums possible will not pay you;
No one will pay you more than $0.02 per e-mail or click, as standard member;
$100-10000 cashout are only dreams;
Carefully for your money. Don`t Upgrade if that PTC has not a good reputation;
"10 years subscription" - Not give us any guarantee that PTC will be online for 10 years, and I noticed that many of them disappear in less than 6 months. Be careful where you choose to invest money!
After click ads, possible will appear: Do you CHEAT? Pick the Number, Which 1 is the month, Pick the animal: you must answer correctly;
15-20 PTC sites can be enough;
Read many forums about PTC sites;
Read Scam Detector (scamdetector.info) and PTC Scam List daily.
