This game’s journey
—
Uses a downloaded BTC/USD daily close snapshot; this is not real trading or investment advice.
Make ten choices without seeing the future
You begin with $10,000 in cash. By default, the game draws ten unique dates with CoinGecko closes from the beginning of the dataset through the day before its latest point, sorts them chronologically, and reveals them one at a time. Each round shows only the current date and close.
The default is five required buys. The $10,000 total buy budget is divided evenly, making each default buy $2,000. Every configured buy must be completed before settlement. Pass becomes unavailable when the remaining rounds equal the remaining required buys and sales.
Changing required buys or emergency sales resets revealed dates to the new minimum, upward or downward. You can then manually increase the date count.
Survival mode tests your sale timing
Survival mode introduces two emergency sale missions by default for medical bills, car repairs, or home repairs; you may choose one to three. A mission stays prominently visible for three turns, and you choose which CoinGecko close to sell at. On the final turn, selling is the only available action.
Each target sale equals one buy amount. With five required buys, both buy and sale amounts are $2,000; with four, both are $2,500. Sale proceeds remain as cash but do not increase the required buys or the $10,000 gross buy budget. Three sale missions require at least twelve revealed dates.
Settle everything at the final close
After every decision, the dataset's last date and close are revealed for the first time. Final value is remaining cash plus the final value of BTC held. Survival results also show completed sale missions, total BTC sales, and the net amount bought.
Real closes, not real investing
Every playable date comes from the downloaded CoinGecko BTC/USD daily-close snapshot. The final point is reserved for settlement and excluded from the random rounds. Results are entertainment shaped by historical data and a random sample; they do not represent a strategy's performance or future returns.
