You are in a very tight position OP, you planning to invest in Bitcoin is going to be very hard for you, because you are not making any money one way or the others it's better to learn skills right now, find ways you can make money first before thinking about investment, at your present age I believe you have the time to learn a lot of things, I did the same when I wasn't making any money, I was living with my parents and I found Bitcoin back in 2016, I took my time to learn everything about Bitcoin and crypto, it's because I was still young and I have no responsibilities at all.
That's why I said you have all the time right now, you can look for some skills to learn around crypto world, trading is a good one and coding too, just take your time to do some research you can find a niche in crypto space that's interesting to you and start from there.
Many people who don't have anything that's bringing them money forced their way into Bitcoin investment, two guys from my city also did the same thing, today they aren't holding any Bitcoin because they are tired, they are jobless and they decide to take my advice less seriously, I told them to look for job first but they make me seem like I don't want to teach them and I did, now they know why I was hesitant in the first place, investment is not going to be fun if you are not earning money monthly.
Yes, you are right there. At Op's age, he can be considered young in the field of bitcoin business. It's not necessary to rush everything; it's good to do it slowly and at least smooth out the learning about it.
Then, once the OP really understands the beauty of Bitcoin's concept, he will surely experience the smooth profit of the thing we are talking about here. And I also think OP will give it enough time to study it.
