Title: Is it safe to refund to (one of) output address(es)? Post by: Stn on August 24, 2013, 04:57:28 AM Imagine you got bitcoin transfer which you want to refund. For certain reasons you can't contact payer. Is it OK to pick originating bitcoin address (or one of them) and send bitcoins there? Won't these bitcoins end up somewhere in limbo?

If it was BitcoinQT its fine or even blockchain.info. But if they sent with inputs.io they won't get the refund. Since you don't know its probably better not to risk it.
