Trading simply means that you buy a cryptocurrency at one price and sell it at a higher price, and take the difference as profit.
Just like you buy gold when it's cheap and sell it when it gets expensive.
People trade currencies like$BTC and$ETH and $XRP and others, and more
But keep in mind:
Trading is not a game of chance; you need to learn, follow the market, and know when to buy and when to sell.
If you are still a beginner, the most important advice:
Start with a very small amount, and consider it an exercise, not an investment.
