It's true that young people do need to earn money first to invest in an asset like Bitcoin, and for some, that's certainly not easy. Especially for young people who aren't completely dependent on their parents, this certainly makes it even more difficult for them to make a decision. As you said, young people who may have just graduated from college are faced with several options for earning money: working for someone else or starting their own business. I think if I had to choose between those two options, I would definitely consider my personal financial situation and my skills. Basically, if I really didn't have enough money to start a business, I would probably work for someone else first.
I don't think there's any other option. So, maybe once I have a job and a salary, that's where I might start investing in Bitcoin (if I have discretionary funds). Sometimes, for young people who are truly independent, it's very difficult to have discretionary funds, especially if their salary is small and their needs are much greater. So at that point, I think it's better to find a job first, gain experience, and investing in bitcoin when you have discretionary funds. Because basically, to start a business you need mature knowledge and strong capital.
No one ever has discretionary funds or income. A person has to find discretionary income through proper financial management. We don't need a job or a business to invest. What we need to invest is a source of discretionary income. If you have a job, if you spend all the money from your salary, then how will you invest? If you can reduce your extra expenses and find discretionary income through proper financial management, then your investment will be good.
If you invest with the money you need, you may not be able to hold your investment for a long time. Because when you invest with emergency money, if you need that amount of money, you will have to sell your holdings. And invest with money that you don't need
