What if BestChange have something like this too. Im sure everyone would be eager to post contructively as having bonus for quality post is really sweet. But of course just a mere suggestion, as BestChange already covered a lot of payments weekly. Also I think its gonna be tough to choose with 58 participants if ever.
I was in Bustadice before I joined BestChange and I got that bonus quite often often, and I admit it was a nice thing to see your name among those 4 that shared 100 USD. But as you said, BestChange has much bigger number of participants (58 compared to 16 in Bustadice), so it wouldn't be an easy thing to do, to choose few winners each week. It would take a lot of extra effort.
