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.
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.
Any newbie who is starting his/her crypto currency investment and chooses to start with altcoins is solely responsible for whatever outcome they got. As someone who is new to an environment, before you do anything there you have to ask questions so that people around there can give you the proper orientation. As a newbie you don't just jumped and invest in anything in the name of investing in crypto currencies. You should look for people ask people who are already experienced in it before investing. Anyone who has been in the crypto space for long will surely advise you that as a beginner you should start your journey with bitcoin investment, as your money is more secured in it. Bitcoin has always been there and will continue to be. But there were altcoins that where there few years ago and today they are no where to be found. So I will say it's a big mistake for newbies to venture into altcoins.
