I can have financial stability with any amount of money, even the minimum necessary to survive. Financial stability just means I have to respect my financial limits, never spending money I don't have or that I will miss later for emergencies.
Being responsible with your money like I mentioned, you will be able to grow your savings on long run, earning more and more money (from passive income) each new month. So you can upgrade your life standard step by step as time passes, always respecting your financial stability limits to not compromise your progress negatively. With the correct mindset and with access to the right tools (bitcoin), everyone has a chance to thrive, doesn't matter how much they make in a monthly basis.
I think in the same way, many people think of someone rich when they think of those terms, but the truth is that someone that may seem to have everything on their lives as they have a nice house and a nice car may not have financial stability at all, and if they get fired they could be on the streets on a matter of months, while a person with financial stability could get fired and they could withstand this condition for years.
