Everyone prefer Bux PTC sites because of the higher earnings. Earnings per click are usually about $0.01 and referral clicks are between $0.005 and $0.01.However some are scam and kinda trade-off of sorts.  Because of the higher payouts, some bux sites tend to fail a lot because their payouts per a click are usually higher then the amount they charge for advertising. Some are succesful like these famous bux sites below. Nowdays it's difficult to get referrals for them. I wish i started long time ago, for more money.

POTENTIAL EARNING FROM ONE BUX PTC SITE BASED ON AVERAGES

• You click 10 ads per day = $0.10
• 20 referrals click 10 ads per day = $2.00
• Your daily earnings = $2.10
• Your weekly earnings = $14.70
• Your monthly earnings = $63.00

I believe everyone know these sites. In case some of you haven't ...today will be my lucky day. Join them! They're long running sites, sustainable and paying.
