Good luck with the auction, would have loved to get the coin but hey what can you do.
You can have the Bitcoin on hand to buy the item youre placing bids on.

Usually there is 24 hours to pay when winning an action.
Guess you are not familiar with cold storage.
You got me too, my trust obviously shows I know nothing. Thank you for your input. Have a nice day. Ignorant comments will get you far here....
