it's never too late for an investment. you can start at any time. but you also have to pay attention to risks and also some understanding to be able to remain consistent in your investment planning.

because you are a beginner, actually no crypto asset is completely clean from risk. but if you choose Bitcoin, then it is the best choice. You certainly see quite a lot of assets on the exchange, but for a start, Bitcoin will be good enough for you.
and one more thing, don't forget to have a hardware wallet to store your Bitcoin. never put it on an exchange.
