you do not trade crypto ali, you buy and hold, you are right it is extremely volatile and the worst part is influencers try push " leverage " trading in crypto which is just asking to lose all your money.
remember that you want to own your crypto , not be " trading " it on a exchange and not actually own the keys. If you really do want to start investing in crypto, the best thing you can do is first learn how to properly store it, because ive heard countless story's of people losing there crypto simply because they didnt understand the storage of it, and it really is the most important thing especially if you plan to hold for a long period of time
