Great place to get a practical feel of the global financial marketplace. Intelligent competent traders willing to provide support. Check your ego at the door.
Cons
Most people are born & raised agriculturists. Very few are fit to hunt for a living... only the top 5% of people succeed in the business of trading, the following 10% (if smart enough) follow the 5%. The remaining 85% have no idea what they are doing. Its a zero sum game.
