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.
Having multiple sources of income is an assurance that we can buy and hodl for the long term but it's not enough to sustain long term investment. Every Bitcoin investors that wants to sustain long term investment needs to understand and practice financial management. If you have multiple sources of income but lacks the discipline to make realistic budgets on how to manage your basic expenses and discretionary funds you're not going to sustain long term hodl.
An investor with a single source of income that is equivalent to one of your sources of income can sustain long term buy and hodl if he truly understands financial management. It is not so much about how much your total income is, what matters is how well you plan your budget to balance all your expenditures. So far you have a discretionary funds you can always allocate some funds to buy Bitcoin.
