Let me break it down for you clear and straight.
It's not necessary to use leverage, especially if you're not experienced, because it's the fastest way to lose all your capital and even end up in debt. The most prudent approach is to trade spot: you buy the asset, wait for it to pump, and then sell. This way, you can cover your obligations and still pocket some profits.
Leverage carries a very high risk. A small move against you can completely liquidate your position. That's why many people end up losing their funds.
Big corporations use leverage because they have advanced information, high-frequency trading tech, and systems directly connected to the market servers. While one person is clicking, they've already executed multiple trades.
So, if you don't have that level of tools, the smartest thing is to trade spot and manage your risk. Discipline and control are key; greed and impulsiveness are what lead most to lose.
