Instinct is not always right and can even be misleading if it is based on the desire for big returns so easily without having to work hard. See how easily many investors lost their money on ponzi projects or investments in the past, it was also because they followed their instincts to expect easy returns.
One that is recommended before investing is to study what your investment assets. One should not invest in crypto if they don't know what crypto is and how the market works and know what its huge potential is in the long term. Investments are promising, but not all of these investments will bring them the expected returns in the short or long term.
It is always difficult to know beforehand how much knowledge is the minimum necessary to become an investor on a particular market, after all if you knew that information then most likely your knowledge of that market will be higher than the basic amount of knowledge necessary anyway.
With that being said, we must remember that all markets are full of pitfalls, and the market of cryptocurrencies is not an exception and if anything is probably one of the most dangerous markets for newbies, as the ratio of good coins versus shitcoins is awfully low.
