Congrats to the HI roller. I am also about the same age on the freebitco but never got the opportunity to roll for a $200 prize. But since the FUN program was launched on the site with its premium membership benefits I am more than happy to stay there for that very purpose. Later I became a big fan of the Betting section on freebitco. It's unique ranges, simple design, and live stats of how many % peeps are betting make it easier to play.
I have shifted my focus to collecting more and more WOF and playing them together. The last batch that I rolled was 2000 WOF and got awesome prizes back to my account. Moving further, my favorite part is multiply wager. I have been wagering so much that my account is always has Active Bonus that helps me boost my wagering amount. My current personal stats is still in loss, but I love to play it anyways in the hope I will hit the jackpot or reach 25c requirement to avail the profits.
The premium membership they launched 2 years ago was a good move and especially in the very beginning, the WOF spins were very rewarding. I am also saving up my WOF spins right now (currently at 820) but just waiting until the price of BTC drops down so the base prize on the wheel will increase lol.
The betting is also nice on the site, not a lot of options but the pari mutuel betting is something unique and can be interesting.
I am surprised you are having 820 WOF spins because I was thinking mostly they are expired soon, but now I will recheck and try to have numbers like you, I have usually done after every week because once mine were expired, and then I never take any chance to go after few days.
There is no doubt I also like betting system which is good and fair enough with some good number of lotteries and rewards are also give extra bones for the users even I never have any referral but mine alone stats are mostly good and enjoyable for me now thinking to have few more things which will allow my chances better for winning more from here.
