investing in a new project means that you are ready to lose a lot of money, it's better to invest the money we have in those who already have a product on the market
That's right, investing in a new project is very risky, because they don't have a clear product on the market, so the potential for losing money is still very open, and if it's optional it's still good to invest the money we have in those who already have a product in market.
However, investing in new project brings us the chance to double or triple our investment. The only thing that you can do is to learn how to do good research about the project that you're in. Also, tracking its roadmap and finally you just need a little bit of luck lol!
