I have seen a lot of pressure when I started investing into Bitcoin, I had no job but I was able to buy some coins and gather some money through faucets and airdrops, this isn't impossible at the time but very challenging.
As someone who have past experience about getting exposed to Bitcoin without any actual source of income, I am now advising begginers to make sure they have a source of income at least before investing into Bitcoin.
If you can feed yourself comfortably that's when you will think about investing into Bitcoin or any other investment plans, the world is getting tougher per year, I was lucky in my own time because free source of making money in crypto space was still possible.
Now things have changes drastically, only those who are joining IDOs are making money now, airdrops now sucks so much, since Arbitrum days there isn't a better one till now.
