Only a little money, don't think about investing in the crypto market. Because only rich people play games created by themselves. Those who have little capital and are lucky enough to wait for the right time to burst.
Correct, with little money, you're better off doing smaller things such as buying and selling things on the Internet or simply opening up a small business in your area. Buying bitcoin and holding it for profit is too risky and someone who has little money sure doesn't afford to lose such money. There really isn't much you can do with little money when it comes to business but do something active about it like selling food at your workplace or at home. And honestly it's much better than buying bitcoin and then holding it because investing in the crypto world doesn't guarantee money and you can be waiting for years only to yield small profit from it. At least buying and selling something will give you profits right away and losing money from it is very unlikely.
