Trading and the cryptocurrency market are all about risks, whether it's new projects or old ones, you should always remember that you are playing with fire and your hands can burn at any given time. There are a lot of old projects that couldn't perform in their initial days but did pretty well recently, take GNO as an example, and there are also projects that were extremely popular and trusted but then failed miserably and aren't able to recover anymore, such as LUNA.

So, there is absolutely nothing wrong with making investments in new cryptocurrencies, the thing is that one should be able to do enough research and understand the market very well to understand whether a project has potential or not.
