How do we the get the $5 cash backs after signups ? Do we get in the website account itself or you can send it to our btc address ? You're using the referral link in the url as it states ,do we get money immediately after sign up?
$5 REFUND PROMOTION
GET YOUR US$5 KICKBACK!! EMAIL US YOUR DETAILS, AND ONCE YOU'VE ACCRUED US$50 OF BITFINEX FEES YOU WILL BE SENT YOUR KICKBACK TO YOUR DESIGNATED BITCOIN ADDRESS.
So basically you have to invest 50$ in the Site, to get 5$
Refund You are correct.
It is better than nothing, and I don't know of any other Bitfinex referral system that will give you any sort of benefit better than this.
