can i know TWODOLLARPTC is a scam site or not

Hmm i dont know this site.But in genaral all ppt sites are turning in to scam one after the other.So i think go and join but its better not to invest any money there either for referals or for account upgrade.

The deal with that site is what it calls dollars aren't really dollars...they're like points which will eventually be converted into cash. The conversion rates are always disappointing, too; you'll be earning pennies, not dollars. So it's like a scam in that it deceives people, even though it may eventually pay you.
