I agree with your balancing financial security and Bitcoin accumulation strategies but I don't quite agree with your allocating the percentage that should be used by people's for their income. Our needs and financial obligations are different so generally allocating the 50 30 20 strategy can only work for people with same kinds of needs but generally it is not everybody that can afford to remove 20% or 30% of their income for discretionary funds. Some theories are perfect on paper but in practical they are not easy to implement, your basic expenses is more important than allocating funds into emergency funds and investment funds.
Sometimes 50% or more of a person's income is not sufficient to take care of their basic expenses so what I advice is giving priority to expenses that you cannot avoid like food, if you have children allocating funds for their school fees and the rest that you cannot avoid. If a person's income is not surficient for basic expenses they cannot allocate any funds for discretionary funds and your strategy is not for them. The economic situation is quite hard in the country and everybody needs to find legal ways to increase their incomes so that they can be able to allocate funds for discretionary expenditures.
I gree with you because judging from the way our economy is at the moment most people can't bost of having discretionary funds, either because there income is too low or there responsibilities are most time overwhelming, because of that this set of people might just have to settle for emergency funds and investment funds as you said.
But there is always a way to accumulate money to be able meet up with this his perfect strategy of balancing financial security and Bitcoin accumulation. And that way is to look for multiple sources of income, I know you have to worker harder most times if you have multiple sources of income, but it's necessary for stability especially in this present economy.
There are many of us whose income is very low. Those who have very low income can earn money by working extra, but there are many people who become physically ill if they work extra. They should invest with the amount of income they have through proper financial management and by reducing extra expenses, finding discretionary income. Through the DCA method, a person can invest even with a very small amount of money. If a person is able to find $ 10 discretionary income, he can invest. The importance of proper financial management of a person is very important.
But if someone is able to work extra. He can sit with a small meal in the evening or do the work he is good at in his spare time. If someone's income is very low and if he is able to work extra, then he needs to work extra.
