Like you said, there's no investment without risk but some investment has a very high level of risk and that's why some people try to hold back their investment and do a very good research or study about the asset before investing. Currently, there have been so many scam altcoin projects and anyone that is interested to invest in altcoins really need to do a proper research if they don't want to lose their money, it's better to even invest into Bitcoin and hold for the next bull market to come, that one is a very good risk.
