I know that making people sign in to vote is a lot of work for them.

But, we need to track what people vote on Beansight to calculate their expertise on prediction.

But maybe the possibility to vote on a prediction without sign-in could be a first step to make them connected to Beansight.

Yes, you could have them vote and then give them the opportunity to sign up. Store a cookie or something so they can only get one vote as an unregistered user. Of course, this could be hacked, but you could put in provisions to check for multiple votes from the same unregistered user's IP, etc.
