Welcome to the crypto world and mostly the newbies are buying bitcoin and ethereum for the less risk because that coin have a lot of supporters so it is not easy for it to dump the value unlike the other coins who is more risky that can result your money to lost but the more risky the coin the more higher profits you get because also the value is very cheap and once it rise it is very huge profit will come to you at this moment taking risk is needed because even market movement is good it have chances to see again bearish market.
I believe newbies are not the only ones buying, even the huge corporations are buying, right now everyone is buying bitcoin because it is a great investment to make in the future. Obviously it is not going to be easy and it is not going to end up being profitable for someone who has no patience and can't wait for it, but that doesn't change the fact that people can't make money from this, they can totally make profit from it as long as they can wait, some people just rush way too much.
My suggestion for anyone who wants to invest would be to sit tight, buy however or whatever you want, buy something that is decent, doesn't have to be just bitcoin but don't go too risky, but at the end just keep that for at least few years. I can guarantee you that not waiting and being scared and panic selling will not be helpful for you, it has to make some profit for you but if you can't wait, it will not profit at all.
