I'm not sure how you're going to focus on crypto If you don't have enough money to buy Bitcoin nor have a knowledge to day trade. Realistically, you need to find an online job to sustain your daily necessities and If you can make enough spare money, you can invest it with Bitcoin in long term.

Covid has been so tough for all of us for more than a year now and vaccines' effectivity has been in doubt because there were some claims of death after the shot from the vaccines.
