Also make sure that you have set up your wallet where you will be holding your bitcoin and make sure nobody has access to the seed phrase. As a newbie feel free to ask questions about bitcoin here anytime you feel lost and need directions. People here will assist you.
There is no need to figure out the bitcoin wallet prior to getting started investing in bitcoin, yet of course, any bitcoin that is purchased through third parties such as an exchange is not really your bitcoin until you move it to a private wallet, so it is good to learn about various kinds of private wallets and figure out how to get into the practice of keeping most of your BTC off of exchanges, yet at the same time, you don't need to learn those things right away.. It is probably better to get started first and then figure out the order in which you want to learn things, while at the same time learning that there are risks in keeping your BTC with any third parties, including but not limited to exchanges and/or also getting lured into products that tell you that they will hold your bitcoin and pay you yield.. Newbies have to be careful to avoid those kinds of ways of custodying their BTC and/or getting too greedy trying to earn money with their BTC prior to just building up their BTC stash and figuring out ways to hold it privately and also holding their BTC in ways that they UTXO sizes are not too small. .. so UTXO management can become an issue and a concern, even though it is not something that has to be learned right away and before buying bitcoin. Of course the more BTC that you buy in the beginning, then the more justifiable it is to make sure that you are not holding it on exchanges, especially if you start out buying several thousand of dollars of BTC or several months worth of your income/expenses worth of bitcoin.
There is so much truth and clarity in what you have said here. I noticed that beginners always tend to be curious about figuring out which wallet is best for them to secure. Before starting our investment we must know how to do things right especially keeping our coins safe. There are thorns of wallets out there. With just a few clicks on the internet -(' what are the most secured wallets to store my bitcoin') Google will provide lots of wallets and it is in our right to choose which we want after reading their features. Its now general that people prefer listening to strangers online and YouTube before choosing a wallet. When they can choose for themselves. To be honest, beginners should not be afraid to disagree with strangers on the internet, or even with so-called experts that have podcasts, social media pages, and resources on YouTube. Because at the end of the day, the investment/security decisions they will be able to understand and convince, trust, and uphold are the ones they made for themselves when the going gets rough or uneasy. But if they choose to listen to someone's opinion or advice then it gets to be for the right reason and they should know that they will take responsibility for their action, not the person which they took their advice or opinion from.
We have to be careful with various wallets that we might choose, since they could have backdoors to steal your money, especially if they are not widely known and if they might be closed sourced, then they might have hidden code in them that either could steal your money or to spy on you... which spying can be done in other ways too, besides just through wallets.
Of course, the more value that a person accumulates, the more security he should want to have, which might be in a hardware wallet or even multiple hardware wallets set up with multi-sig, which has its own potential complications.
Part of my earlier point was that a guy with small amounts of purchases, even $10 to $100 per week, might be better off getting used to his purchases and other aspects of his cashflow management prior to figuring out which wallet and/or wallets that he might use in order to take his coins into his private control and custody and hopefully without compromising his private key that he needs to figure out how to sufficiently/adequately safeguard... which he might not immediately be in a position to figure out a lot of the wallet considerations, yet if he is starting out by investing $10k or more into bitcoin, he might need to figure out in a more expeditious time how to remove his BTC from third parties, and surely there could be some folks who are buying ETFs and otherwise getting BTC price exposure, and they might not realize that they don't really own the BTC that they are buying, even though it still could be a way for them to get started to get BTC price exposure, yet at the same time, they may need to spend some time learning about the trade-offs of really holding your BTC versus merely buying BTC price exposure.. and so some folks might feel that they don't even have time to learn about bitcoin, and buying through something like a ETF is amongst their better options, so we cannot really stop people from making those seemingly inferior choices that still might be more convenient for their current situation... and I would likely suggest that it would be better to start a BTC investment journey even without holding your own keys rather than failing/refusing to get involved at all, since even some folks will be inspired to learn more about actual BTC once they start to get involved in BTC in one way or another and even through something like buying shares in a BTC spot ETF.
I suppose people learn at their own pace and sometimes they might make mistakes and sometimes they might just need some time to start to fit bitcoin into their lives, whether it is fitting into their finances and/or psychology, and/or whether they need to time to learn more about it.. which I have frequently advocated that we don't need to know a lot about bitcoin to get started, even if we might merely be getting BTC price exposure rather than buying actual BTC, and at the same time, it can take time for various persons to start to learn more about BTC so that they might be able to become more empowered by their learning about BTC. And, surely there are some folks who might not know much of anything about bitcoin beyond considering it as a kind of number go up (NGU) technology, so that might be as much as some folks are ready, willing and/or able to learn about bitcoin, so there still is a need to leave people to their own devices and theories, which still might end up being a sufficiently strong bitcoin investment thesis, even though some of us might consider such an investment thesis to be incomplete and overly simplistic, but it still might end up working out for the person who invests into bitcoin based on such a perspective.
