Thank you. Checking I see you have already sold 5 2018 bitcoin gold binary rounds @ $2000 or 1.62 times spot gold. 1.62 times spot platinum would be $1360. Seems reasonable that you could easily sell 5+ one ounce platinum bitcoin binary rounds as that price would be lower than the gold rounds. Depends on whether the numbers work for you. It would also complete the set: bitcoin binary rounds in silver, gold and platinum. As for your ultimate coin in platinum I would have to see it for myself to judge if the premium over spot is matched by collector value; I suspect it will knowing the quality of your coins. Sorry for derailing the thread.
There are a few reasons why a multiple to spot markup wouldn't really be possible with a platinum binary round vs gold binary round. For example, the designs of the gold and silver are nearly identical. I even had the binary spell out Golden to match the characters in Silver so that it would be a simple design edit. Platinum would require a larger redesign. I also have 1 of the dies on my binary rounds that can be reused, so the 2018 rounds only required 1 of the dies to be edited/crafted. A platinum version would need 2 entirely new dies, with both requiring a redesign. Then there is the cost of blanks, which can actually be higher than gold blanks due to their rarity (not sure if this is true for a 1oz blank, but it certainly is for the size I'm having made for my upcoming round). Finally, the minimum minting costs would apply equally to platinum/gold and not be based on spot price.
I hope that explains why I wouldn't be able to offer a platinum round for $1,360 without taking significant risk and hoping the exchange rate went my way. Maybe if I took pre-orders I could get the price down below the $1,600 I suspect I'd have to charge, but this would be more about pleasing customers than anything else, so there would have to be demand for it.
