If you are so new to bitcoin and asking such basic questions maybe you need to consider the matter of bitcoin in terms of yourself, and whether you are going to get involved in bitcoin or not.
It should be a lot easier to pay attention, study bitcoin and maybe start to ask more improtant questions in regards to your own preparations if you figure out some kind of strategy and start to follow it, even if you might just start with $100 per week or if you cannot afford $100 per week, then consider something as low as $10 per week while you are researching and learning more about bitcoin in order that you might figure out what is going to be your position and your targeted allocation, if any. It can take a while to both build a targeted BTC allocation and also to figure out why you are doing it and maybe how to do it in such a way that is comfortable for you whether that is accumulating through DCA, buying on dip, and/or lump sum investing.
That would be one of the best strategies. Because most newbie would be learning about bitcoin without having any in their portfolio, due to low confidence and trust. Most of these are triggered due to a particular event he or she or someone they know of have encountered in a certain investment. Most time alot of newbie got themselves woumded by investing in a particular altcoins due to lack of proper research. Which may have leave a certain scar that have affected their confidence but still if they have started making good research they will know that "all coins are altcoins except bitcoin" Which is superior to the others in many ways. So is only when you are learning about a certain altcoins you need to hold horses (not making any investing yet) but learning about bitcoin you can start with accumulating some quantities to your portfolio as you are learning about it. Even using DCA strategies to buy $10 per week, as time goes on as you see the beauty of investing in bitcoin you would surely increase your funds in accumulating more bitcoin and the end you will that all your efforts wasn't in vain. When you see the good changes on your portfolio at that time.
