Trading simply means buying a cryptocurrency at one price and selling it at a higher price, and you take the difference as profit.
Just like when you buy gold when it's cheap, and sell it when it becomes expensive.
People trade currencies like $BTC and $ETH and $XRP and others.
But keep in mind:
Trading is not a game of luck; 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 a practice, not an investment.
