Ah, the wonders of budgeting! It sounds like a solid plan you have there for micro-budgeting and teaching good financial habits. Setting aside a portion of your allowance each week is a smart way to build savings over time. And yes, it's similar to dollar-cost averaging (DCA) in the crypto world, but with good old fiat currency.
It's great to see that this method can be used not only for emergencies but also for those fun plans like travel or gifts without straining your present budget. After all, who doesn't love some extra funds for spontaneous adventures or showering loved ones with presents?
And you're right about many people neglecting budgets - it can be quite detrimental indeed. So whether you use this technique yourself or share it with others, it can certainly help foster better financial planning and maybe even provide some additional BTC buying opportunities along the way. Happy saving and zapping!
