And when you have good management skills, then it becomes easier to manage your assets because when you invest in Bitcoin, it becomes easy to manage your funds because emergency funds are part of management skills, it makes you want to focus more on the investment, and it is underestimated. And another important thing is going to be having a source of income, because having a source of income and when you have source of income then DCA becomes easier to implement. And even if there is no source of income, just that will make it very difficult, and there won't be consistency, and investing money will make it slower to accomplish your goal, and people will eventually understand the importance of having money coming in to invest, so investing needs a lot of commitment.
I will only be talking about the highlighted words, when investing into Bitcoin, for consistency of your accumulation, discretionary income is greatly needed, not source of income as you claim, because their are so many folks out there that have a source of income but still can't figure out their discretionary income, so the ideal word you should be using when talking about accumulating consistency is discretionary income not source of income.
I agree with you mate, discretionary income is the most important thing for anyone to have if he wants to start his bitcoin investment and not just a source of income, because that's not enough. Some people have a source of income but it's not enough to take care of their basic needs and monthly expenses. This is why you must be able to figure out if you have a discretionary income from your income and know how much it is, in order to enable you know if you can start your bitcoin investment or not and how much you will use to be accumulating bitcoin in your own convenience.
If you don't figure out if you have a discretionary income and you rush into purchasing bitcoin, if at the end it happens that you don't have any, you will be forced to sell the bitcoin that you bought to take care of your basic needs which is not supposed to be so, because you might be unlucky and run at loss if bitcoin price dips below your entry point.
