Quote from Rickshaw Man:
You won't get any interest when you trade currencies thru globex, but you will if you trade in the spot market. Last summer I was making an additional $5.00 a day holding EURUSD long, not to mention the profit from price appreciation. It's like a daily dividend. GBP, AUD pay some awesome interest for holding long in that currency.
I think most people who bash the currency markets are just venting from their own mistakes, and that is one of the big problems you face when trading, not being able to admit you were wrong.
Sure some of these outfits are rip offs, but you will encounter rip offs in every day life, not just in the forex markets.
