You have a point here no doubt, but I know of someone that doesn't know anything about the Bitcoin ecosystem, all he just have is faith in Bitcoin, he believes that since Bitcoin is an asset that appreciate in value overtime, if he can get a huge stash of it, and hold for a long time, he is definitely going to make cool money.
That guy bought Bitcoin base on when the funds is available, and due to the fact that he is being payed amnesty, he uses all of it to buy anytime the money comes in, and he did it for like 8 months when Bitcoin was around 18k to 30k if am not mistaken, he eventually sold his holdings when Bitcoin rose to 67k, and it was easy for him to hold because aside the amnesty that he is being paid for, he is actually working in a private establish firm.
Why am I saying this? Am saying this because most investors don't need to know everything when it comes to Bitcoin, they just need to have the basic knowledge of it and what is required to hold, that's it, then the stash of it in your possession will determine how profitable you might be in the future.

That is true and I think the best phrase to this is that they want to believe invest investing on Bitcoin will offer them quick income that is automatically change their financial status from poor to rich.

It is really annoying after telling interested enthusiasts that Bitcoin is a good source of income if invested and  hold for long period of time which investors do not have to rely on it on quick Incomes and then imagine such newbies or enthusiasts disapproving this slow concept of Bitcoin that they can not invest on Bitcoin if it can not provide quick incomes.

Then I will always ask such person that... Okay, tell me. What source of investment is provides a quick income in the reality world of physical assets if not trading?

However, I would always tell such persons that... You can as well trade on Bitcoin if you want a quick income but be it sure that the risks of lost on trading is tendered to come than when just buy your Bitcoin and hodls while awaits for a positive flows towards the market price increases where the values of your holding multiplies.

Two concepts that make someone able to achieve financial improvement to be better if applied consistently but these efforts also need to be considered regarding strategies to increase bitcoin ownership regularly.
If some beginners do a buy and hold strategy for the bitcoins they have, then that is the right choice because bitcoin can indeed provide returns that are in accordance with how to hold it in the long term.
But what needs to be considered next is how a beginner can continue to consistently collect bitcoins if they do not have good financial resources on their journey.

To make all this easier and not make them stop investing, a strategy is needed that can be applied according to the capital capabilities they have.
The method is to utilize DCA as a strategic step so that they can slowly increase the amount of bitcoin ownership they have.

Agreed.
If a person knows enough about Bitcoin and learned about it - he won't have shaky hands with it for a moment, imo.
That's the key to hodl patiently.

It all depends on the person involved, how long he wants it and how much Bitcoin he going to sell off for his immediate needs. A need will arise that'll take all the Bitcoin he had stored for long, it's depends. What actually makes Bitcoin investments and holdings works is the steady flow of income from different streams, if you expect to only get funds from your holdings when you get certain profits then bare in mind that your Bitcoin will finish off quickly because bigger your needs, then bigger your Bitcoin withdrawal.
