I have not heard about this bullish accumulation of a thing and it is sounding like being passionate to accumulate Bitcoin against all odds. I hope I'm wrong but the right way to invest in Bitcoin is always with discretionary income to avoid a situation where you will have to sell Bitcoin to meet your basic needs, which is not a good thing to do. Even though you may not have meet your accumulation goal in terms of the quantity of Bitcoin in your portfolio, it will be better to imbibe consistency than to rush the process since with time you will definitely meet the target. In other words, the concept of slow and steady wins the race.
If you are accumulating Bitcoins and want to hold them for long term then best approach is to accumulate them through discretionary income. While your job salary or business income can be used to meet daily requirements. Why discretionary income is important is because it allows to dormant your Bitcoin for longer duration. Without discretionary income or if you are accumulating bitcoins with your salary then you might cash out your bitcoin in the long run, which completely destroys your plan of long term investment.
I don't completely agree with you on this. Limiting Bitcoin savings to "discretionary income" seems like a good idea, but it doesn't take into account how wealth is actually made. People that were able to save a lot of money didn't wait until they had money left over after spending it; they put Bitcoin at the top of their list of savings, insurance, or retirement accounts. If you simply buy with what's left over at the end of the month, you probably won't ever have a big position.
So, I think the most important thing is not to avoid paying for Bitcoin, but to plan your money well. Pay off your bills, set up an emergency fund, and then think about Bitcoin as a long-term investment. You won't have to sell when things become rough, and you won't have to wait for "extra money" that might never come. Being truly enthusiastic about saving requires being disciplined and making sacrifices, not just being easy.
