As is this is ten years from now, I use CHF as a reference to minimize effect of inflation. CHF 1000 is currently USD 1078 (so roughly 5% price at market creation)

Bitcoin may experience changes and/or forks, so resolution will be the about the currency we find first when entering "BTC" in a search engine.

If price is close from target, the reference site for pricing will be choosen amongs leading ones at that time one month before market resolution.

If there is no price because nobody bothers to make the blockchain work or because it's not possible to buy/sell bitcoin anymore, Bitcoin will be considered as "gone" and market resolves to YES. If that happen before 2033, market will resolve YES early, after a month to see if it can recover.
