I'm sorry for the caused inconvenience. I do understand that some wallet setups may not be accessible in such a short notice.
That being said, I do think it was a fair call to discard your bid, because you have no history here. The common practice in these cases is to ask for a safety deposit.
There have been cases here where new non-established members, members without history, have trolled and even wrecked auctions by bidding and not honoring bids. It would have been unfair to other bidders to let you bid without a safety deposit due to that. I do think that you're a legitimate member. It's just that certain status or safety deposit is required to make auctions fair for everyone.
You are right that auction rules do not state anything about safety deposits. But as Lauda mentioned, it's kind of a common practice around here to ask newbies to provide safety deposit. I'll be having this notice in my future auctions. Also, I should've mentioned this to you earlier, but it simply didn't cross my mind, and I'm sorry for that. I hope we'll see you participating in future auctions.
