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 totally agree with you when you said that if you want to accumulate Bitcoin and holding your Bitcoin in a longer term through the means of using a discretionary income and it occurs to me or draw my attention that the discretionary income you just mentioned above you don't have the full knowledge about what a discretionary income is all about, because if you know you can't be using your salary or business to meet your daily requirements, so i want to explain what a discretionary income is all about if you have forgotten so early, a discretionary income is an income gotten from your salary after all the payment of bills, so after the payment of bills what remain is the discretionary income than you still saying that you can use your salary or business for your daily requirements.
