I like small investment because it is less risky for traders As a beginner I started with just $50 . Then I invest some more money .If I had much amount I divide it among 2 or 3 trading accounts so I not do emotional trading with small investment .
I think if still beginner will better start with small investment, after passed in demo account with good confidence hence start in real accoiunt using small investment is better than use big investment because newbie stll lack in experience.
