if you are already DYOR and sure about this project, then you may invest in the project, because the most important thing is that we are sure of what we will invest, but my advice is that you should use money that you are ready to lose, because investing in a new project is definitely has a big risk, but if the project you invest in is successful, then you will definitely get a big profit too, therefore if you are sure, then there is nothing wrong if you invest in the project, because maybe you can get a big profit from investing in this project.
To be honest, I'm not sure there is any money worth losing most especially when we talk about crypto currency investment, because the higher you buy the more the profit or loss and most times, I see people creating post like using $500 to invest in altcoin. I believe before you invest in any coin you should have read the white paper and do some search about the coin to find any trace of scam, or if it's a scam project, Or else you are just a gambler who is using crypto to cover up. I have seen lots of investors who follow after trend without taking caution, though most times they tend to come successfully. So if you are sure of the crypto you want to invest in, go ahead, after all you are the one responsible for your risks and profits.
