make sure not to listen to anyone who tells you any random coins. This is a good place to rip-off people that's why you should only trust yourself. Before you invest in anything you have to make sure to understand what the project/coin is about and what problem it tries to solve. It's a bit unclear to many that the coin has to offer some actual value in order for you to gain value. There are for example all these different coins, that do the exact same thing, they don't add any innovation to the market and they are just trying to take advantage of this entire crypto boon that is happening. Even though you can invest in a coin it doesn't mean you should. Look for something that is worth putting your money into and try to understand the "deeper" qualities of the coin.
