Well, of course I have an account on Paxful. it’s my business to offer, I called the price, if someone is interested then he will turn
The last time i checked, paxful exchange reputation is good and i don't see any reason why it would be hard to advertise referral program through signature code for such exchange if you're been honest here with your proposal before offering a shady service which no one will agree to do in the first place. However, i dont see the exchange giving you up to $20 per the person referral.
