Here in this thread we only know and talk about bitcoin. And I will advise you to only focus on bitcoin. Because I know that what you are referring to as crypto are altcoins/shitcoins, and we don't encourage people to venture into that here. But if you still want to talk about those your crypto you will have to learn it elsewhere but not in this thread. Our discussion here is centered only on bitcoin and nothing else. Now that you have decided to invest in bitcoin, you should have a long term mentality. For you to see some reasonable profit in your investment, you have to keep investing and holding your bitcoin for at least 4 years and above. And there are certain things you need to put in place before starting your investment journey, they are;
Emergency funds, reserve funds, floating funds etc. And you have to have a good source of income. It's good you already know about DCA strategy. And one thing I will tell you is that, don't invest money that you will be needing in one or two years time in bitcoin. Also make sure that you have set up your wallet where you will be holding your bitcoin and make sure nobody has access to the seed phrase. As a newbie feel free to ask questions about bitcoin here anytime you feel lost and need directions. People here will assist you.
