Such great project! Such an amazingly unique result... more than a good, is a piece of art, you should sell it as such. Have you tried to advertise it in other platforms? Maybe an auction or a Dutch auction could help find the right price for it?
Knowing more about the idea, the motivation and the inspiration behind will also justify or help give it a value. The piece itself, as you present it, could be valuable only for aficionados.
Tell a story... And for 1 BTC as asking price, it must be a really interesting story! That's what give this piece real value, not the piece itself.
We only sell directly to buyers/collectors, we do not have access to Dutch auctions so we have never held an auction there.
