How he got those referrals is not known. But if he purchased these referrals then he must have spent a lot of money to buy them becoz the cost of one active referral pack of 20 referrals is $25. True he may get back the money he spent in the long run. But the question is whats the guarantee that u get active referrals in a referral pack??.

If these 2000 referrals were active then he wud have earned $80 per day becoz each referral can earn you 4 cents per day in clix4coins site. Whereas he is just earning $3-$4 per day. What if they too stop clicking??
