I completely agree with you. There is no deserving person in this contest since it all comes down to luck at the end of the day. This contest is similar to the wheel of fortune without any minimum wagering requirements.
People who have zero idea about BTC price predictions won this contest several times all thanks to luck frankly speaking.
Yeah there are members who might have purely speculated prices for the month end but still managed to win the first prize because they were lucky and bitcoin was close to their prediction but on the other side some analysed it closely and set a target range but they were not right so we won't say they should win because the rules don't say that.So all are deserving in one way but if you are lucky you will win.
Then this shows that even if how good you are in prediction or technical analysis still you are not sure to become a winner of this contest since the result might come different as the market still unpredictable regarding on how it moves. You just need to be lucky to spot the nearest price prediction to win on the contest so this give equal chance to other to try their predictions and join the fun on this contest held by them.
