Why pay for hosting with BNB
BNB usually sits in the same exchange account or wallet you already use for trading fees, which makes it the shortest path from "money I hold" to "invoice paid" — no withdrawal to a bank, no card, no currency conversion desk.
BNB Smart Chain fees are a few cents per transfer, so paying a $14.99 annual invoice on-chain does not quietly cost you 5% in network charges the way an Ethereum mainnet transfer can during congestion.
