Liquidation usually incurs a fee. Once you add up the buyers fee to convert fiat-> Bitcoin, the Bitcoin transaction fee, and the seller's conversion from Bitcoin->fiat, Bitcoin's marginal cost benefit over credit cards is slim. As miners become less subsidized by block rewards and must rely more on fees for covering costs (and/or full blocks cause a spike in Bitcoin fees), it seems like the cost-per-transaction may swing in favor of fiat payment schemes.
