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.
But actually they don't need to think about that having multiple source of income is needed before they could start on their long term investment journey. Since somehow they could start with the amount they currently have.
They can work it out to have multiple income stream and increase their discretionary income later on especially if they are eager to find multiple source to cater everything they need.
What's important at first is they take action to accumulate and they don't wait for anything then make it a reason to delay their investment.
One source of income is sufficient and enough for an investor to achieve his or her long term goal what is very important is how committed, how consistent, how determined and how devoted and passionate they are towards there Investment. May I also inform you that multiple source of income doesn't guarantee successful investment especially in Bitcoin investment, you can have several sources of income and yet you don't have the above mention and if you don't have it, is as good as waste because you can not do anything meaningful with it. Multiple source of income can only be interesting and sweet if you actually know what to do with it.
