It is never mandatory that you must have a strong source of income before you can start up Investing in bitcoin but you can gradually grow up your bitcoin portfolio with your little source of income provided you have your discretionary income ready, having a strong source of income to me sounds like your income Flow must be huge before one can start accumulating Bitcoin meanwhile you can be accumulating Bitcoin with the little income you are earning or making every weeks or months using the DCA strategy and then grow more your source of income over time.
What I like about bitcoin investment is that their is no minimum amount that you can use to invest in bitcoin, even if you have a low sources of income, then you can still
Invest in bitcoin, just that you might not be able to invest so much in bitcoin, but you also going to be holding some bitcoin which is better than you not holding anything. You can just start small, then with time you can keep on accumulating more bitcoin, you shouldn’t wait till you have big amount of money before you invest in bitcoin. Just make sure you plan yourself, and if their is any way which you can increase your sources of income, then that’s better, but also don’t starve yourself just because you want to invest in bitcoin.
That's how flexible Bitcoin for investment purposes since anyone could start at what amount they like to spend. Those impression that Bitcoin is expensive to start with is just an crazy assumption since there's no need for anyone to start to buy the whole Bitcoin since any fraction is good enough for them to start their investment. What's more good about it is this investment gives us less pressure especially that what we only need to do is to buy then we can forget about it and don't need to pay much attention about current situation happened. Compare to other investments which we need to watch always about what's happening since if we don't pay much attention there's huge chance that we might lose our capital.
Those wrong assumptions they made like people need to have strong source of income first or anything that contribute for them to pause their accumulation is bit off and cause some delays. Since if they pay attention to start right away for sure that they won't get bothered about unnecessary things and provably that they would just pay attention later on how they can increase their income so that they can accumulate more Bitcoin in future. This attitude is I think good for the investor since provably that they can accumulate more especially if they eager to start right away.
