Please, advise
I decided to increase FREE BTC reward by buying lottery tickets. I have bought some lottery tickets and then I see that "51.4298% archived toward the next bonus" on main page. Ok
But after some hours I see that only "50.1327% archived toward the next bonus". Why this percent was decreased with time?
Every time you make a free roll the percentage decreases a bit. I don't really know the formulas to calculate it tho.
