Great thoughts, but good luck convincing anyone. The ultimate failure is literally written into the mathematical logic of it. Every dollar out MUST be a dollar and change coming in because you always sell a bitcoin to someone else, plus the accumulating overhead. The total "investment" must always exceed the amount people are walking away with. That's literally the defining characteristic of a Ponzi scheme. It could go on for years yet, or collapse tomorrow, but it's mathematically impossible for it not to collapse eventually, leaving someone stuck for the total dollars that walked out as profit or got spent to mine. There's no magic--it has to add up to zero.
