It is true that investments can bring us income, but it can also make us lose. We cannot guarantee that investing will always bring us profit, so we need to have another main job in addition to investing.
Investment has two parts for profit and risk of loss, it is difficult to determine an investment with passive profit even gold is also at risk of falling in price during a pandemic and economic crisis conditions, but with regard to crypto investment I have no doubts to start investing when prices are low and determine investment targets for the long term use cold money so that we focus on achieving profit targets in the future.
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.
It's true when talking about cryptocurrencies it is a risky investment and I think almost everyone knows that,
