Sometimes trading could also give you more profit than investing.
It is all about skills, timing and knowledge if you could earn from trading why wouldn't you use it.
Why not use that skills and capital to earn rather than letting it sleep and wait for the profit?
Money that is left to sleep will never have any profit because profit will never come by itself on any fiat money, but if the money has been converted into assets such as Bitcoin and has been considered as an investment, of course there will be profit when the price of Bitcoin increases. So there is nothing wrong with someone trying their luck in investing even though trading can also be another field to reap profits if someone does have more skills and knowledge in trading. But if you pay attention to the risk side itself, it is clear that trading is much riskier than investing so this must also be the main consideration for those who want to make a profit through trading because market conditions always have fluctuations that are not easy for anyone to predict.
