I found this your statement above very discouraging and misleading, because you don't need to have a stead job and income before you can start investing in bitcoin, because waiting  to have millions or billions before you can get started with bitcoin may delay your investment journey and you may even end up losing interest to invest in bitcoin if you see that the price of bitcoin is too high for you, so all you need to invest in bitcoin is a source of income, because you will only accumulate Bitcoin with the little amount of money you can afford which is your (discretionary) using the DCA method, and before you know you will see yourself accumulating a good portion of bitcoin to hold for long term 5 to 10 years or more.
