The advice is good, but without practical training, it will not benefit the user, as the user will link the advice to its importance after it occurs, such as not leaving your money in a central platform, he will not understand its importance unless he actually feels that his money in that platform is in danger, and therefore setting examples will help a lot.
Reading can definitely help you, but actual trading will give you more experience to use in your trading journey.
You can read all the books but if you are not trying it on your own actual trading, that would be useless.
Remember, you are in crypto. Each project has their own features. So one major strategy from your previous coin won't be applicable to the new one.
The more experience you will acquire, the more you will become adept in crypto trading, as one look, and you know where the coin is heading to.
