It builds up slowly. It can be faster, but then we have to play more, and more... if we raise the stakes we can get hands on even more of their tokens, but that comes with certain risks, I guess we all know that.
The "prediction contest" is nice, but I don't find it so interesting... but I would be interested to see & participate in a new slot challenge.
Thanks for sharing iv4n; this is valuable information and you are earning a nice amount. If the daily distribution would remain the same (normally it will drop a bit as more tokens are mined) you would be getting 3,427$ as passive income every year.
