My friend told me the forex trading earns a lot more than normal investment. Any advice?

In his book "Attacking Currency Trends", Greg Michalowski estimated that in one month, 68% of retail currency traders lose money. The next 32% of traders could be divided into four groups: -

(1) 13.5% make 1 to 3%

(2) 13.5% make 3 to 6%

(3) 2.5% make 6 to 10%

(4) 2.5% make more than 10%

It would not be easy to be consistently profitable but the result should be alright if one could avoid incurring big losses in the other months.​​​

Forex trading is a completely different skillset from investing! Anyway, if you are trading stocks, there are also stock traders who earn alot everyday from trading stocks. However, if you are a trader no matter Forex or Stocks, it takes up a lot of time. Your friend said that he paid a broker to do it for him, and gets 200-300usd back. How long has it been doing it for?

There is no such thing in the world as free money. Even investments takes time..
