I think ptc sites are good if you do have a lot of referrals.
Exactly PTC Sites are good when you have lot of referrals then its good passive earning

I don't think even after having lots referrals ,ptc site are still paying similar to faucet and that wont make any good amount.
Yes its not good amount but i guess if you manage to have big amount of referrals in Neobux / Clicksense you may have pretty awesome life with it lol , although personally i never get addicted for PTC , way too much small earning and not worth the risk actually . Grandbux is good and fast earning which is still running i guess over 3 years now , i used that before and it was amazing earning but again PTC earning really not worth the time if you don't have big team behind you
