Investing can also be trading, depends on the timeline we’re talking about.
What you should be more focus to is to increase your knowledge about the market, and know if you can do trading or you prefer more to become a passive investors. I prefer more long term investing, but I can do trade as well though recently the market seems not in favor to my decisions and that’s why I stop trading for now.
^No, don't mix it up.
If you are in trading, go for trading, and for investing, it should be only on investing.
Because if you are in trading your investment, you don't know if it will make a profit or not, or it will easily wipe out your entire investment once you made a wrong decision. Separate the amount of money for trading and also for investing, because they are both different.
