PTC upgrade

I would second ranacseruet's opinions above in regard to Wordlinx, Clixsense and Matrixmails. As you are from US, you can try upgrading at all the above sites. Patricularly, Matrixmails gives you lot of benefits when you upgrade. However, upgrading after having some active referrals would make you earn quickly. Regarding those BUX sites, I suggest you remain free member. Upgrading at Bux sites is too risky. They may disappear or change their TOS at any time.

if u want to upgrade, upgrade only very trusted sites like wordlinx, clixsense, matrixmails. they are running for years , so very trusty. after you are getting some regular revenue from this, try others like neobux, perfectbux , ara-bux. they are also trusted till now , though, they are not even 1 year old yet. so, always be very very carefull before investing money. did you join 'ciao'. if not, join that. that don't need any upgrade. just join & make a lot of friends there. you will get a good money. all sites i have mention till now are on my profile. please join there. also, you can suggest me some sites that are old,legit & aren't on my profile. Thanks
