Quote from TraderZones:
If in the USA:
your futures trading accounts are segregated and backed by several layers of protection
your forex trading account is based on "please please Mr. Broker, please don't go out of business and take a lot of my $$$ with you or hang my account up for months or years while trying to sort out your assets." If you were a Refco customer, you understand this.
Or even "please don't trade against me (research dealing or no-dealing desk). If you have longterm forex account, you may understand this.
I wouldn't touch a pure forex broker with an 11 foot rope.
If you covet and wish to seriously use much higher leverage, you DON'T understand anything.
Commodities have a more favorable tax situation, taxed at 60/40 cap gain ratio. It is hard to beat if you make serious trading $$$. Plus, year end tax reporting is a breeze.
Also, forex is a hard nut to crack for longterm profits. Electronic currency futures provide what most need.
That seems to cover it.
