Play with Up&Down to try and predict the most popular cryptocurrencies' trends, i.e. whether the price will go up or down.
To make your forecast, pick a cryptocurrency and study its graph. Select Up if you think its price will go up or Down if you think it will go down, and choose the duration. At the end of your forecast, you'll know whether you guessed right or wrong and you'll get the relevant XP. Doing a forecast costs 1 life.
The reward varies according to the duration. In the event of a tie, you won't get any reward.
Remember - you can only make two forecasts at the same time.
