It is always risky to invest in crypto coins. Not only for new coins, old coins or top coins also have risks in investment. But the risk can be varied or have different levels. Investing in top or old coins can have smaller risks because most of them are already proven for many years to exist in crypto market. They are also owned by established projects that have good funding and experience in crypto space. While for new coins, we don't know how good the coins to survive and develop in crypto market since they are just launched. It should take some time to show us how the potential of those coins in the future. That's why we need to be more selective to buy new coins. Some of them can survive and grow well, but some can be delisted and be dead coins in the future.
