I think the best thing you should do is getting started rather than waiting to have multiple stream of income before getting started to investment in bitcoin, by the way you don’t require multiple streams of income to invest in bitcoin, what you need to invest in bitcoin is a discretionary income, and that is just a money that is left after paying for your expenses and your bills, you could possibly start investing little by little ( fraction by fraction) and you can always accumulate with the DCA method.

You don’t even need a stable source of income to invest in bitcoin, what you need to invest in bitcoin is a discretionary income, and that means it’s what you’re left with after paying your bills, and investing in bitcoin is always a good and wise idea, because it will definitely open a good opportunity of building a successful portfolio considering that you’re investing with the mindset of holding for a long term purpose, which I will tell you it’s the best way of investing in Bitcoin and that is holding for a long term, when you tend to be waiting to have everything necessary you like you said, then you’re wasting time and you will eventually be missing out on opportunities of accumulating more.
