X = btc/usd on Jan 1 2023 (16605)
Y = btc/usd on Jan 1 2033
Resolves to ((Y/X)^(1/10)-1), interpreted as a percent (for example, 5% annual growth makes a resolution of 5)
If USD ceases to exist we use the successor currency at the last available exchange rate from USD to the successor currency.
If BTC ceases to exist we use the successor currency at the last available exchange rate from btc to the successor currency.
If USD ceases to exist without an obvious successor this resolves to maximum
If BTC ceases to exist without an obvious successor this resolves to minimum
If AI kills everyone and both cease to exist simultaneously, this uses the last available exchange rate.
