. If money for your investment should take 70% of your total income your emergency funds should not take up to 20% because you are not working to solve problems when though you will always encounter problems a long the line.
Planning your Bitcoin investment like this is a clear sign that you have failed before it even started, why would you even contemplate investing like 70% of your total income?
You should only be thinking of investing with your discretionary income, money left after all your basic needs have been met, but if an investor start his Bitcoin investment or decides to invest like 70% of his income in Bitcoin without sorting out his basic needs first, it will not be up to a week before he falls back to his investment just to sorts out some financial needs, so don't ever do that, invest only from your discretionary income, not 70% of your total income, because that's financial suicide.
Is buying Bitcoin with 70% of your total income a good financial decision? I'd say that it depends on your financial responsibilities. Realistically I'll say investors that makes money but don't have any financial obligations can do that, like young people that are working and living with their parents. If their parents takes care of their immediate needs like food, shelter and are able to provide for them Incase of emergencies.
For majority of people that are investing in Bitcoin it is quite unrealistic for us to use 70% of our incomes to buy Bitcoin because we have unavoidable responsibilities. Before you talk about having discretionary funds from where buying Bitcoin comes from you need to first consider your basic or unavoidable expenses.
For most income earners their basic expenses which they must make provisions for are over 50% of their total income. On average about 40% is what comes into discretionary funds every week or month and from their emergency funds, DCA funds and the rest comes out. So people with financial responsibilities must have budgets for their income otherwise if they're too excited to buy Bitcoin with almost all their income they will sell them sooner than later to take care of pressing needs.
