You are right that many new crypto investors chase quick money which mostly leads to big risks and losses if they do not know what they are doing.
It is common mistake to just follow others into projects that promise fast riches. For beginners it is smarter to stick to Bitcoin because it is less risky and more stable than most other cryptocurrencies which are very volatile and complex.
Starting with Bitcoin helps new investors learn how crypto works and how to keep their money safe without wild ups and downs of lesser known coins. So learning and doing homework and thinking long term are much better than trying to get rich fast in crypto.
