While the prediction page is still at page 1 and you have more time to give your prediction, you can analyze more to give the bitcoin price as your prediction. You can consider this prediction as fun but do not have a big expectation to win because we will have many rivals that are ready with their predictions. Moreover, the previous people will also join in this prediction.
Predict price of Bitcoin is a very difficult task and most interesting one too. Interesting because if you predict it correctly, you will feel you are like genius BUT in fact you are not.

You commented right that we should not think we can predict its price correctly and go to use all money for Futures trading, Leverage tradings or Gambling. Mostly our predictions are wrong and will not give us happy trading and gambling.
You still have at least 6 days left to give your prediction because the first prediction will close on the 15th of April, so do not be late if you want to give 2 predictions at this prediction.
A lot of time but I don't think we should be hurry too much and bet too early. Personally Bitcoin will continue to have its sideway and fluctuation around $28,000 in next days.
