GI-INDEX FX & SPREAD BETTING

Our testimonials speak for themselves....
Before I opened a GI-Index Spread betting account, I was just another real-estate agent. Now, after spending my lunch hours and evenings punting the Euro-Yen cross I've seen more action than a Green Beret after a third tour in Afghanistan! GI offers me the 1000-to-1 leverage and that satisfies my thirst for turbo-charged thrills! If in doubt about what I've got to show for it, just look the satisfied smile on my face!!!
I am not familiar with GI-Index.
In the fam it stands for gastrointestinal, and we know where that ends up.
