Security-wise, to keep yourself safe individually, when you are using a platform, make sure you have a very strong password and enable 2FA for sure. These two are mostly the only options that can keep you safe from hacks and exploits if they are attempted on your account individually. If something happens to the exchange as a whole, that's not your responsibility, and you will be compensated by the exchange if your money is stolen but only if you are using a platform that has ensured user's funds, Binance is one of them.

Other than that, if we talk about trading itself, I wouldn't recommend doing a lot of experiments as a newbie. Just stick to the old and recognized cryptocurrencies so that you don't lose money in the initial stage until you become experienced and gain enough knowledge, and then you can start doing experiments on new coins and projects.

Lastly, don't get into future, it's not an easy way to make a lot of money, it's not good for newbies because there are too many risks.
