I would be careful in presuming that anyone starting in bitcoin needs to actually hold his own bitcoin in the beginning. Sure holding bitcoin is important and learning that holding bitcoin is what distinguishes it from other assets, but at the same time, I think that I a person (a beginner) can work up to holding his own keys and he might spend his first one or two years in bitcoin just building up price exposure and maybe learning about how to hold his own keys, and so people can be in different places in terms of how much they are able to learn at one time and how long it might take them to get to a point of being able to hold their own keys.. so I don't see anything wrong with beginners starting out with mere price exposure and realizing that they are not really owning bitcoin even though they are starting out by investing in price exposure and perhaps otherwise getting their finances and psychology in order so that they can continue to learn about bitcoin while investing into it (in a price exposure way)..
Yes, the more empowering aspect of bitcoin comes from having it (at least a decent amount of your BTC holdings) in your own possession, yet there are a lot of folks who have BTC in their possession, but also keeps some on exchanges and through third-parties too.. and so it is up to each person regarding the proportions of such and to realize the power of holding decent amount of BTC yourself... because none of us really can know when third parties, governments or even hackers might end up gaining access to coins that we are not holding in our own possession.. and yeah, hackers are getting more sophisticated too.. so anyone holding their own coins have to be careful not to get socially engineered or otherwise tricked or forced out of their coins.. which is also an ever changing topic and even very smart folks, long time bitcoiners might not realize some of their own self-custody vulnerabilities, even though it remains preferable to have a decent amount of self-custody when it comes to BTC.. but not necessarily telling everyone that you know.
If beginners can really have the mindset of holding their Bitcoin investments for a long period of time from the beginning, they start investing in Bitcoin without thinking of taking their profits in the short term, they will really enjoy their Bitcoin investment process. They will not worry so much about the price they will like to get the price of Bitcoin. In fact, I don't expect any newbies coming to invest in Bitcoin thinking of taking their profit in the short term.
I believe by now a lot of Bitcoin investor should know the risks associated with exchanges. We have witnessed a lot of exchanges that collapse, and investors don't have access to their funds again. And one thing again is that when someone leaves their Bitcoin in an exchange, it means that is not only person has access to the Bitcoin, and once someone is not the only one having access to it Bitcoin, it Bitcoin it already at risks. meaning any issue can come up later with your Bitcoin investment. The best way our Bitcoin can be properly secured is by using our personal wallet, which is called non-custodial wallets.so it is good advise to always store our Bitcoin in non-custodial wallets that will have full control to especially hold term Bitcoin holders.
