There are 3 options to profit in the cryptocurrency industry. according to my version like this:
 - Trading: It is called a way to get more money by trading cryptos, either by transferring between them or by providing exchange services.
 - Investment: There are many cryptocurrencies with a good future, but I only recommend Bitcoin and Ethereum.
 - Gambling: sometimes beneficial and sometimes detrimental. I don't recommend it at all (risk high)
Don't invest yet until you're able to understand the whole concept of cryptocurrencies and how volatile this market is.
There is a process before you can do that, however, you can start by buying bitcoin with around the smallest amount that you can test to see how it feels like owning it but you won't feel the fluctuations since it's just a small amount.
