Investment is usually for a long term in contrast to trading where you buy and sell in short duration. Trading is not for everyone rather only experienced people who have spent their time and effort learning the trading can handle it with perfection up to some extent. Investment is secure and less risky if you have the patience to wait for longer duration. For newcomers it's advisable to stay away from trading because it can give them heavy losses, the best way to move forward in crypto for newcomers is to invest for long duration.
What you said makes sense because I personally did something like that when I was new to crypto, but while I was investing in the long term, I also spent quite a lot of time learning about how to trade so that now I can do both at the same time thanks to the experience and knowledge I have in the past. This means that everyone can trade and invest in the same year as long as they are able to manage their emotions and capital better because if we refer to the potential for losses, of course it is more likely to happen in trading and those who often experience this are beginners who have no patience so they are more covered in panic when they see the condition of the coin they are trading is experiencing a price drop.
