It sounds like you are being too biased for cryptocurrencies, if you say investing in gold is also risky, then cryptocurrencies are also much riskier, no exception. Crypto is a very new form of investment compared to gold or other forms of investment, and it is always classified as the riskiest of all forms of investment.
If you can hold crypto long enough to make a profit, that should also happen in gold or real estate. Gold is not as profitable as bitcoin or crypto, but it is much safer.
Investing in bitcoin is the safest investment when it comes to cryptocurrencies, but everything that does not concern bitcoin contains heightened risks, all the more risky if you generalize all altcoins, because some of them are more reliable like ethereum, and some are outright garbage, and they are really useless . There are different types of investments, each of them has its own advantages and disadvantages, but you need to invest your money in those that you understand and understand what you are doing.
