There is no way you can make money doing speculation without risking money. Forex trading may sound easy way to make money, but it is easier to lose money as well. This is just as safe a way to make money, as gambling, betting etc. Stock market would be slightly more predictable.
Most people start trading, make small profits, get addicted, lose money, in attempt to recover, lose even more money and finally quit after losing way too much. During this time, your job, peace of mind - everything would be affected. Better do some REAL job and stop trying to make easy money.
