At first I thought that it is a costly mistake and the person won't get their money back.
But the examples of miners who have refunded BTC gives me hope that the person in the story gets a refund.
However this brings to thought, two pertinent questions
- Is there any extrinsic reward if the miner refunds the BTC?
- Is there a punishment for the miner whether big or small if they refuse to make a refund even after it has been verified?
