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.
You have a point. It is true that many people have been scammed by altcoin fraud, but I think altcoin investment is okay for those who are interested in investing in the short term. Some people think that Bitcoin is unstable and that it is beyond their patience to manage investments for a long time. And considering that altcoin can give a good profit in the short term, they invest in altcoin. At one point, they are seen in the circle of hackers and they lose everything. In this regard, I think Bitcoin investment is above all investments. And if you apply the DCA strategy, long-term investment can be an ideal symbol of a high economic power in your future.
