The Illusion of Mining Bitcoin on GPUs
Copyright: Sanjay Basu There is a certain kind of optimism that never quite dies in our industry. It shows up every few years. A new wave of hardware arrives. Someone looks at a powerful GPU cluster and asks a simple question. Can this print Bitcoin? It is a fair question. It is also the wrong one. Because what you are really asking is not whether it works. It does. In the same way you can cross an ocean on a rowboat. The question is whether it makes any sense at all. The answer, if we stay honest, is no. The Scale Problem Nobody Escapes Let’s start with first principles. Bitcoin mining is not about compute in the abstract. It is about compute shaped in a very specific way. SHA 256 hashing. Deterministic. Brutal. Repetitive. No room for cleverness. This is why ASICs exist. A modern Bitcoin ASIC pushes well above 100 terahashes per second. That is not a typo. That is the baseline. Entire racks scale into exahashes. Now place a GPU next to it. Even a powerful accelerator like an A100 is ...
