Submitted my prediction although the very date I wanted to predict was already taken ;( there should be a way to distribute reward but let more users predict same dates.
Hmm, that is right.
So, technically, we need:
1. One integrated prediction contest across fb, twitter, reddit and forum, and possibly with a higher pot than 0.1 - up to 0.3BTC.
2. Only one prediction per person. Make rules stricter to make that happen. How about requiring a Da Dice username? Either way, only someone who knows DD can make a more accurate bet. It should reduce (but still not completely) the multi-account abuse.
For handling that:
a) DD username?
b) Minimum activity requirement?
c) What else? I am aware of certain people having multiple full member and sr. member accounts. Having a minimum wagering requirement will help, but it has other limitations like restricting genuine people to make the prediction... Any ideas on this? Da Dice certainly don't want it to be restricted to, but want to make it more fair.
3. Allow multiple people to make the same prediction. Certainly the first to do so, should get the most.
