This discretionary income is for people that has very limited money around and want to buy Bitcoin. Someone with millions in another investment can decide to invest their momey on Bitcoin and don't even think about discretionary income, they maybe using their discretionary income to pay some minor bills but someone with small amount of income doesn't have choice but to use their small income to buy Bitcoin which may not be a stable guyas usual.

Well, I still think that when you don't depend on one source of income as a low income earner, when others opportunities arise you will have more income to but Bitcoin without relying on just discretionary income. There was a time had Bonk when it was nothing but the profits I made from it, I didn't think twice before I used it to buy Bitcoin and so luckily, Bitcoin price was way cheaper that time than it was today, this are the kind of opportunities in talking about.
