Cryptocurrency Prediction Contest: game manual

Coinranking's prediction contest

With Coinranking’s weekly Prediction Contest on Twitter, you can win a prize by predicting the price of varying cryptocurrencies. Every week we choose a new cryptocurrency, which means a new chance to win. The closest prediction wins around $100 in that particular cryptocurrency!

How it works

Every Friday, we will pick a cryptocurrency (listed on Coinranking and Indacoin) to predict. Then you will have five days, until Wednesday 23:59 UTC, to predict its value at 12.00 UTC the next Friday. The first closest prediction wins. Sponsor Indacoin delivers the price via their app. So if you win, you’ll need to download the app, in order to receive the coins. 🏆

What you have to do

  • Go to Coinranking’s Twitter.
  • Retweet Coinranking’s main tweet of that week’s prediction.
  • Comment (on the main tweet) your price prediction in USD and use the $-sign.


  • The price is according to the Coinranking database.
  • Our automated system chooses the winner.
  • Bots are not allowed, suspicion is enough for disqualification.
  • 18+ only.
  • The first closest prediction wins.
  • A dispute period of 24 hours after the winner is announced. Any grounded claim on the prize within this period will be granted.
  • Your latest tweet with prediction counts.
  • The first dollar amount in a comment counts.
  • Indacoin gives the price via their app.


  • Check first to get an idea of the current price development.
  • Use a decimal point (.) or comma (,) as a separator between the dollars and cents.
  • Do not use interpunction to separate thousands.
  • Only tweet once.
  • See the image below for a good example:
