I answered a question about this coin but I forgot to make it public, so I publish it here:

>> When I originally bid on your gold coin (101BTC), I was bidding with the
>> expectation of 1BTC=1.80USD. About $180USD was the most I was willing to bid on
>> the item.
>> Now that 1BTC=3.57USD, I cannot afford my bid. I did not anticipate a rise from
>> $1.80/BTC to $3.57.
>> I realize that this is request could be damaging to my reputation on
>> BiddingPond or in the BTC world, but I simply cannot afford to pay $360 for an
>> item on BiddingPond at the moment. I don't have that kind of disposable income
>> this month.
>> I sincerely apologize for the inconvenience that I'm sure this will cause for
>> you, and I would be willing to pay you several BTC for lost time if you find
>> that to be necessary.

> damage your reputation as a buyer. Only bid a bitcoin amount you currently own
