Separate payout variability from profitability
Ask what a smoother cash-flow line actually tells you.
Source foundation
Mining uses proof of work; pooling can reduce payout variability. Bitcoin developer guide: mining.
A worked example
Two invented projects each receive 100 units over ten days. One receives everything on the final day; the other receives ten units daily. Their timing differs, while total receipts are identical. If both spend 120 units, both lose 20 despite the smoother second line.
Original hypothetical example. Amounts, people, events, and scenarios above are invented for learning; they are not historical observations or forecasts.
What to take from it
More regular receipts do not by themselves imply a positive margin.
Try it on paper
Calculate the result if expenses fall to 90 units.
Keep the assumptions beside your answer. Check the result before applying the idea to a different situation.
