Maybe a single 1 sat/byte fee txn is actually a miners transaction that got included in the last block because they wanted to mine their own and didn’t care about the fee. If so, then you risk losing 6.25 BTC for a 112 sat fee.

Maybe it works 99.9% of the time. But you’d need to do it *millions* of times for it to make economic sense. Until fees overtake the reward, the empty blocks will continue 😆
