Contest over - how should I hand out the prizes?

So this is kind of what I feared/expected after the last few days.

Here's the list of biggest rising coins the last 7 days and none of the people who entered the contest has named one of them.

Of course after seeing this list, I realize that most of these coins are probably shitcoins without much long term value and the whole purpose of the contest was to discover promising altcoins that actually have a future.

So I'm asking again, especially to those who entered the contest. What would be a fair way to decide the winners?

I'm also considering setting up a new contest with some better parameters...

Anyway thanks to all those who took the time to enter.
