First Auction Coin instantiation is live now ! @ https://auctioncoin.app/
There’s whitepaper published by anon-real there.
The first instantiation is based on decreasing price auctions. I think fixed-time auctions with increasing bids would be more interesting game.
=========================
And I think, similarly to Auction Coin , there could be OptionCoin.
That is, a contract is periodically issuing new tokens, and selling them via Ameican CALL options. taking exercise price from DEX. Funds from selling options, as well as from exercising contracts are going to buy OptionCoin tokens back from the DEX.
