Don't you think it will be to be a low coiner than been a NO coiner? From your unstable income you can still figure out if you have discretionary income to start up with your investment you can be buying little fraction of it, if you also cheek and see you don't have any discretionary income to accumulate Bitcoin you can lock up till when you have realize that you now have a discretionary income to get started then you start, you might miss buying opportunity while waiting to get a steady income, you don't necessarily need steady income but you have to have discretionary to kick off your investment.
I understand where you're coming from, but you must know that to get started with your Bitcoin accumulation, there are certain things that should be a must have, and having a discretionary income is one of those, an investor should discover whether he has a discretionary income from his income before he starts his accumulation and not after, so if you're yet to discover your discretionary income or your original financial situation, I'd suggest you take a moment to reassess your financial situation and be sure that you've actually got a discretionary income and then you can get started. I try not to see reasons why one may not get started with their Bitcoin accumulation, but there are certain situations that may as well require a NO coiner to stop first and take the necessary measures first before getting started because the results might turn out to be far worse than one who had not started.
I understand that you are thinking about ensuring people's investment. But your thinking is a bit wrong. We need to think about long-term investment. But for that, it is not that we have to arrange for discretionary income in advance. But it is better to invest with discretionary income. Because none of us want to break it again after starting investment. So if we can invest with discretionary income after completing all our family expenses, then we will never have to think about breaking the investment.
But if we delay starting investment to collect discretionary income, then it will be kind of stupid. Because we all know that there is no specific time to invest in Bitcoin. If you are looking for a bear market, then you may miss that market while waiting. So instead of waiting to collect discretionary income, start investing by extracting discretionary income from your regular or irregular income. Remember, you should not wait to start investing. Every second is important in investing.
