Overall, I completely agree with your assumption, because having multiple sources of income will certainly ensure our Bitcoin investment remains untouched or unaffected. However, I believe that in addition to having multiple sources of income, we should also cut back on non-essential expenses. I believe this is also crucial. It's essentially the same if we have multiple sources of income but are wasteful with our lifestyle. Therefore, it's better to combine multiple sources of income with a simple lifestyle. And that way, I'm sure our Bitcoin investment will run more smoothly.
There is no doubt that a multiple source of income may really be of help in increasing our discretionary income however our expenses is what determine our discretionary income. If we can be able to cut down our expenses then our discretionary income will increase however if the reverse is the case then our discretionary income will reduce. So even if our cash flow increase as a result of multiple source of income without us reducing or cutting down on our expenses our discretionary income will not increase but rather there will be a great reduction. So working on our expenses and making such that we cut down on all unnecessary spending is really crucial in increasing our discretionary income.A good cash management and not just having a multiple source of income is what that is going to increase our discretionary income.
