Payment = settlement in bitcoin. There is no gap to arbitrage. You are simply projecting a fiat problem that you may mistakenly believe is some fact of life or political inevitability, onto a technology that doesn’t have this issue. It simply *cant* be exploited in that way. If a technology allows exploitation or arbitrage somewhere, then it will be exploited, but in this situation, and in this particular way, #Bitcoin makes this form of manipulation impossible.

(The proof of this is MtGox, FTX, Alameda, and the 100s of other insolvencies in the space, they played the exact same game that our banks and the fiat financial system does *as a rule,* but Bitcoin refuses to play… so they did, very quickly in fact.)
