OP, $200 is really that not big to make a decent profit in here but as a start, it was enough. As a student, you don't need to choose numbers of altcoins to invest but just to focus on 1-2 coins. If I were you, I only took BNB or ETH. It supposed to be a long-term goal and there is no need for you to keep checking the market every day.
Cryptocurrency is not a money button.
Cryptocurrency is primarily a technology in its decentralized form.
If you need money then look for a job or additional income, without knowledge of cryptocurrency you'll most likely lose your money.
That is why OP is here as he took this as an opportunity for him to grow his $200. That probably he knows that risk in this field and he is trying to picture it out in order to lessen the possible losses he might get.
Thank you for understanding
