very good for you. To be honest, I do that sometimes too. however, the advice is shown to those who are new to the crypto world or, more generally, the investment world. Many novice investors think that it is very easy to multiply money through the crypto investment route. Therefore, sometimes they do not think about the risks that could occur. they sometimes go all in, or pick 1 coin to choose from, and put all the assets in. well, many of them failed. then they make a statement if this is a scam. Therefore, many people advise to only invest in the amount you are prepared to lose
because their minds are very naive and always think that here is a place of success. Even though this is true, of course it cannot be justified either.
knowledge is everything when a person is on a path and follows it but has no knowledge of it then it is certain that sooner or later he will be destroyed.
Likewise in crypto. when random people enter and without knowledge, they only buy and sell, even though it will work, but it's just waiting for time to be destroyed
