I think nobody from this forum won already a top prize on the WOF spins but we also don't know if such a prize already have been won by somebody else. My biggest prize is winning 1 GT do winning 50 of them is indeed massive!
I think getting a rolex is very difficult especially the other big WOF prizes, I only get 5k satoshi which is the biggest of the other prizes, so I started buying some FUN to get more of my daily WOF so I can have lots of opportunities for big prizes at WOF
