Truth be told I'm actually losing money doing this. The referral program isn't too reliable. In my personal experience, I only get rewarded one out of three times (your experience may vary), and also worth mentioning that it takes up to a month for the "payout." I keep doing this for the fact that I'm still somewhat financially stable. In reality, people who advertise their referral link without additional incentives have more to gain than me. This is a "win" situation for the user signing up either way you look at it.
