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!
That's an insane amount of money then why you want to sell? Remember starting is the tough task but you are already in the halfway mark so just keep doing what you have been doing to reach this much traffic so one day you will be making money as your wish.
