When signinig up for a new acount on Bitfinex.com you can use this referrer code: UttOzlC1zZ
and you'll get a 10% discount on the fees of all trades/margin funding you do in the first 30 days! Just follow the link or copy the code.
Easy as that :)
By becoming an affiliate of Bfxdata you also help in keeping this project alive. When signing up using UttOzlC1zZ a percentage of the fees you normally pay to Bitfinex will go to Bfxdata.
You won't pay this on top of you normal fees. Normally you pay all trading/margin funding fees to Bitfinex, when you are a Bfxdata affiliate you pay 90% of the fees to Bitfinex.com and 10% to Bfxdata.
So not only will you get a 30 day fee discount, also you help in keeping this service online.
