There is no investment that is a correct investment until you make profit from that investment. What everyone is doing in crypto is risk taking from one projects to another and if it goes as we want, then we can consider such investments as the real investment because it is the right choice and the only way to achieve that is through a proper research.
Some people are obsessed with profit because they are used to it and it's difficult to see any other investments that is gong to give you profits like the ones you will see here, sometimes I don't blame them because some crypto enthusiasts says a month here in crypto is like 1 year outside crypto.
Income from crypto, if we are lucky, will indeed be very tempting. Sometimes what we earn in one day can be doubled, when compared with income in the real world it is very far away. I found this with my own friend, who was willing to leave work in the real world because he was focused and devoted to cryptocurrencies.
However, as you said, there is nothing completely true about investing in Cryptocurrency. So we do need further research, and that requires knowledge and extensive knowledge about crypto.
And we can do this research ourselves if we want to learn, and not just ask other people.
