I cannot imagine the magnitude of happiness their costumers felt seeing those BTC's unexpectedly appeared in their respective wallets and that painful feeling of humiliation or distress by the person/s who accidentally distributed the said coins. I do feel sorry for that individual/s. Mistakes do happen but needless to say this was one mistake that was absolutely out of hand. Naturally, it was unsurprisingly understandable that most [or all] of the recipients will not return those BTC's.
Anyway it's not everyday that suddenly -out of nowhere- you're in possession of a remarkably valuable something such as Bitcoin, don't you think? I guess not.
