Pardon my ignorance, but what is the difference between discretionary funds and income.
The difference between discretionary fund and discretionary income is clear. Discretionary fund is a money allocated or budgeted for something that is not really necessary or investment, it's just a fund for hanging out with friends to have fun, or a money for dinning out, or a money for travels, while discretionary income is a leftover money after you must have settled your basic needs and expenses either for the week or for the month. And your Discretionary income is the money you will use to invest in bitcoin and to build your emergency fund and backup fund.
Let me try and break it down,
Discretionary income: is like a form of left over after taken care of your essential expenses ( rent, food, electricity bill etc.) , and you can choose to spend, saved or invest with it .
While Discretionary funds : money you choose to set aside for fun or for personal want and stuff , discretionary funds is from your discretionary income .
For instance my discretionary income is $500 I can choose to make use of $200 as my discretionary funds, while the remaining $400 can go into saving or investing .
