According to me trading and holding are two different things because trading is for short term and investing or holding is for long term.Trading is a business where both profit and loss are faced.If you have a proper understanding of the market and do a good analysis of trading then you can get success in trading.And those who have no idea about trading definitely face losses.On the other hand, holding or investing requires a lot of patience and no one can hold or invest for a long period of time.
