A year and a half ago, i had paid and asked someone in this forum to manufacture the dual cryptocurrency but product was not delivered.

This coin was finally made a reality after 2 years. This is the first coin release, there will be more rare and innovative surprises in store for the future..

1BTC

OGNasty or Monbux for escrow, I will pay any fees/tips for escrow.

1.001 with Ognasty escrow

Can you elaborate on how the private keys are embedded? I'm curious what type of tamper evident features there are, so that one can resell this without fear the key has been exposed. 

From what I understand, the keys are behind the gemstones, which you would have to prise out of the ''coin'' to retrieve.
If I remember correctly, OP has stated somewhere that there will be a metal part which slides out into your hand when the gemstones are removed.

I personally think there could be some security issues with this kind of arrangement, unless the gemstones literally cannot be removed and replaced without it being very obvious this has been done.

OP, will you elaborate on this please?

I should have also stated, I appreciate that you would probably end up having to replace the gemstones if you were to remove the ones in there. I don't know how difficult this will be in practice though without it being obvious.

I would have edited my post, apologies for the second.

ok, i have done escrow with them before.


Current highest bid

1.002

There is a secret chamber inside the coin, and a security device is connected to the private keys which will go off once tempering is detected, alerting the local police.

Just kidding.. :D

Actually, a slot for hiding the physical private keys is located beneath the gemstones. The gemstones are then set in place to conceal the private keys. Before, quite a number had turned down the request to set the gemstones on this coin, saying it cannot be done on something this big.


I understand the security concerns, this is more of a luxury concept for now and coin is currently under going a "presidential race"..  :-X

All the coins produced will be hologram-less. I have plans for a hologram-less tamper proof concept which will be virtually impossible to temper with, unless you can imitate exactly the whole coin.

1.003BTC, with OGNasty or someone else trusted for escrow.

1.004 with Ognasty escrow. If I make any more bids, I will want escrow with Ognasty for all of them.

I didn't realize this auction is so long  ;D

ok no problem..

production cost of this coin excluding the silver alone runs up steeply.

if the final bids are lower than my production cost i might have to list this coin on ebay instead.

Then you should have a reserve in place. A lot of people don't like winning auctions and not being able to get their item  :)

interesting piece of art. It's so huge :) I'm curious how does the protection of private keys work. Could you share more details if it's not a secret, is it protected against x-ray scan?

dense and thick metals can stop x-ray. so im not sure how well the scans results will show up if private keys are enclosed in silver.

There are two high grade stainless steel square plates stack against each other in this coin(like poker cards inside a pack). And both sides of each plate has been engraved with private

keys. Hence a total of four sides will be stacked against each other(like poker cards inside a pack). If x-ray is done, i believe the results will be too legible to be read. Due to the jumbled up

and stacked letters of 4 times.

I already have a method for a tamper proof hologram-less for future productions, and this security level will most probably be the highest possible.
but after i have funds and it will take abit more work.

ok noted.

winner can have the option of NOT funding this coin with 1 BTC.

Btw, 1 ETH has already been funded into this coin.

coin may be buy out anytime before auction end date, if the offered price is right.

Even with good trust, what about the concern that you would have the private key, since they had to come from somewhere?

I do not keep any of the private keys, they are destroyed.. the only left are inside this coin. On top of the positive trusts here, i have 100% positive feedback on ebay for over 10 years.
Buyer has the option to choose to fund the 1 BTC or not. 1 ETH has already been credited in.

I was under the impression the coin came preloaded with both 1 BTC and 1 ETH

"The winning bid is inclusive of the denominated cash value of 1BTC +1ETH, exclusive of shipping charges."

Sorry for the confusion, initially it was inclusive of 1btc and 1eth..
I guess I have to close the auction for now as this coin is still under going an institutional review.

Closed.
