I would say that we can find some good altcoins without risk in these coins. In altcoin Investing has risk but if we can get something good by taking risk it is good for us. So I always try to find some good coins and invest.
Even "good coins" still come with risks. All investors should make enough time and effort to study the coins they want to invest in. If they do not manage to know everything they can about a project, it's possible that they make some mistakes while investing which can lead to losses.
Cryptocurrencies are very volatile assets which is why they are risky in nature. Risks can be managed and avoided, fortunately.
