DoubleCoin ("The Most Awkward Digital Currency... In the World") is a light-hearted experiment in digital currencies. It is the first digital coin with an exponential pricing system, and the first one with a transaction ledger that is kept by hand.
There are 50 coins, and each one has its own number, from 1 to 50. DoubleCoin #1 was originally sold for 1 satoshi (.00000001 BTC), and the price doubles for each coin sold after that. Coin #2 was sold for .00000002 BTC, Coin #3 for .00000004 BTC, and so on.
The proceeds from DoubleCoin are securely stored in the "DoubleCoin Vault," a pile of loose change on my kitchen table, to spite my wife for saying that this was a terrible idea and that no one would ever buy any.
All buyers of DoubleCoins get:
1) their username recorded in the Owner List next to the coin they have purchased
2) control of the website image header for the duration of the time they are owner of the "top coin" (they can submit an image, or one can be designed according to their specifications). After they lose the "top coin" spot, their header is displayed in the "top coin image archive," as long as it isn't obscene.
3) an email from DoubleCoin asking if there is anything we can do to help them out (we don't have much money, but can help in other ways).
The website was updated today to
- show pictures of the DoubleCoin Vault
- add support for DogeCoin
- add a FAQ
- add a header image, which is controlled by the owner of the "top coin"
