Well, when I started my crypto journey, I invested in many altcoins; I made a profit on some and also lost money on some of the projects I invested in. First, you must know that the crypto market has a commonly known characteristic, which is volatility. You can buy a coin with a certain amount of money, and when the coin gets volatile, it could dump your asset so badly that your loss will really be a significant one. That's why you have to invest the amount you can only afford to lose, but to be on the safer side, you can also choose to only invest in Bitcoin, which is very predictable in terms of its bear and bull seasons, but altcoins are too many, and there's no one of them you can actually say they have their specific season to pump or dump. If you are a newbie, start with Bitcoin first, but if you must invest in altcoins, do proper research on the project and only invest the amount you can afford to lose.
