While trading can make you money but it is only the investment that will make the life changing money. There is no comparison of trading with investing and one should focus on investing too while having the trading fun all long.
Trading can be further classified as swing trading, day reading or scalping etc. I think the most profitable is the swing trading while the most difficult is the scalping which is made only for the advance traders or who has lot of time to spend in front of the screen.
I invested part of the money (most of it) in long-term transactions and left part for trading, and in all cases investing (or long-term transactions) was more profitable. At the same time, I spent much less time on them than on trading and I could avoid all the losing trades that happened in trading and took my time, money and my nerves. Now I trade less and less and tend to focus my attention on long-term trade.
