Im sorry i cannot talk about my traffic source but i will give you some details about my paxful account.
The best part about their affiliate program is that it has 2 levels. At this time my paxfull account has 500+ referrals on level 1 and 350+ on level 2. Im making around 0.5 to 8$ per day and also getting around 1-20 referrals per day on bouth levels! I expect that when i reach 2000 referrals on level 1 i will make around 400$ per day worth of btc!
