I don't think the prize is necessary.
It's up to the community we can vote on this
I don't also think that you'll get enough votes for it. People will only join if there's an incentive for what they're about to do without having them pay a penalty if they're unsuccessful.
I don't think that everyone would be willing to pay for that amount if somebody goes $100k first. But that's a good challenge for everyone. I don't think the prize is necessary.
Unless you make this as an official contest with prize escrowed.
Not many people would be interested in this. To me it looks like something extra, and these days doing the extra on here rather than with family just isn't for me. There is also no real incentive to doing this contest and it just doesn't come across serious either...
Exactly, you hit it.
