Majority of the new coins are always a risk. Most of them fail during the initial phases itself and in the long we don't see most of them follow the roadmap in completing the projects. So its not easy to invest in a new coin as its a big gamble to find the right one.
Investing in new coins is indeed very risky because they are still very young to survive in the market so that many new coins fail on the market. I personally do not think to invest with new coins because the coins that are in the top 10 CMC are better and reliable.
