As someone who started with cryptocurrency in 2017, I see that the times hard changed a lot.
In the back old days, you'd need to have a Bittrex account, a Poloniex one and probably a Binance one.
But now? Things are a bit more complicated for a beginner - so I'll try to share some of the things that I think it's mandatory for a beginner to know:
1. understand the definition of a non custodial wallet - Within my years working in the crypto industry I've seen hundreds of people losing their wallet to a scammer because they don't know that their wallet was basically those xx words. Anyone that invites their friend should tell them that in order to protect them.
2. don't keep your funds on a CEX - at least not all of them. Unless it's a really really small amount. We've all seen how easy can a CEX fail and the 'not your keys not your coins' saying needs to be remembered any time.
3. learn how metamask works - MM is already a standard in the non custodial wallets industry. It's a wallet that proved its worth, doesn't have a cryptocurrency (yet) and it's widely used by everyone in the industry.
4. Learn what defi is - Learn, don't test yet. Read about all of the protocols, what is a farm, what is impermanent loss,etc. This is something that will be useful in the future - no matter if DeFi will be a big part of the next bull or not.
5. Dont listen to shillers, DYOR - I don't understand people that are buying whatever twitter influencer said and they believe it will moon. It won't. You're their exit liquidity.
6. Don't ape big - Do NOT ape bigger that you can afford. When buying cryptocurrency, there are a lot of things that can go wrong. Don't go big, DCA weekly or monthly into something that you believe it will do well. Any top 100 crypto has a 2-3x potential, for a bigger one - you need to have a bigger risk appetite.
7. Don't go for paid groups - In 99% of the times, a paid groud is a scam where you are the one that is paying to lose money. In 1% of the time, it's a group that has results and will probably turn into a scam at a later stage.
8. anyone that message you first on telegram is a scammer - don't trust no one on telegram or discord.
9. earn crypto - best way to get cryptocurrency is to earn it.

10. dont panic sell - If you've bought something, and you see it down more than 50% over x weeks/months - don't panic sell it. The product might be good, but the market period might be shitty. Ethereum was under $150 in the last bear market and did a 30x in the bull market. Have patience.
11. set targets - Set a target when buying a cryptocurrency. I'll sell x amount of it if the price reach y. It will help you be disciplined and make a good profit.
