FAQ

CoinRanker lets you predict how the top crypto rankings by market cap will look on a future date. You rearrange coins, set target prices, save a shareable prediction, and later get scored against the real market.

Pick a target date, drag coins into the order you expect by market cap, and adjust prices if you want. Save anonymously or sign in so it counts toward your profile and the leaderboard. When that date arrives, we snapshot live rankings and score your list.

Consensus averages everyone's predicted prices for the same target month, converts each average to market cap via circulating supply, then sorts. Crowd # is that order; Mentions is how many people included that coin. Disagreements highlight where the crowd's expected rank differs a lot from today's live ranking.

Each resolved prediction gets a score from 0–100.

• 70% rank accuracy — how close your order was to the real top-100 ranking. Top ranks weigh more than lower ones.
• 30% price accuracy — how close your predicted prices were (log scale, so relative misses matter more than absolute dollars).

Higher is better. Scores appear as badges on prediction pages once the target date is resolved.

Predictors are ranked by average score across resolved predictions. You need at least 3 resolved predictions to appear. Sign in so predictions attach to your profile — anonymous browser saves don't count on the public board.

No. You can predict without signing in. Sign in with Google or email if you want a public profile, leaderboard placement, and the ability to claim predictions made in this browser.
