Anyone who has dealt with international wires knows exactly how slow and inefficient tradfi can be. I’ve sent dozens of wires to China and they take 4-10 days, you have no idea where the debit-message is within the half-dozen intermediaries it has to pass through, and are left hopefully waiting the process be executed without a human error - which do happen.
Bitcoin on-chain value-transfer works at light speed relative to international wires. It’s also cheaper, programatic (no worry about errors) and require no trust and no permission. From an operations perspective bitcoin is at minimum 10x more efficient than legacy system. Likely more.
