Ok just put it simply, you post your forecast on the maximum and minimum value of USD/bitcoin for tomorrow or any date in future, I'll compile a list of everyone's forecast according to how close they are to the observed values of that day and provide some statistical analysis.
To kick start, I will make my forecast for 23-March-2018:
Max = USD/btc
Min = USD/btc
