its obviously very risk to invest into any new token/coin, make sure you look up all infos before investing
Even investing in old projects still carries with it a great degree of risk, it's all depends on the project one is investing in.
My long stay in the cryptocurrency space have taught me alot of things, cryptocurrency investment is not like investing in traditional assets, there is a great degree of difference, and here in crypto, the earlier you catch a really good project, the better you make profit, don't neglect or look away from new projects because some people say it's very risky to invest in them, like I mentioned before, some new projects comes with not just better potentials, but also with less risk, compared to some other projects that have been for a while.
So, when we talk about which or what projects are more risky to invest in between a new and old project, simply understand that it depends on the project individually.
