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 consistency is discretionary income not source of income.
