So there's always an edge if you can focus on it full time but does that not mean that in part time trading, the profits is lesser. Basically yes, but if you have the best strategy to use, then even at a short term, you can still gain huge profits.
I guess w all start doing trading as a sideline, I mean we will need first capital to do it full-time and our job will help us to start trading unless we have rich parents who can give us money for capital. i have friends who stop working and focus in trading during pandemic since he find it much safer than to go back and forth working in different areas but at tge same time while trading he create some business like store to have extra income. We can say fulltime trading can help us to focus more in the market for potential gains but we should not fullly rely on it when it comes for living as the market is too volatie. We may be in profit today but there are times were at loss.
