I don’t think having high number of spins will increase your odds, as it’s probably fair and most importantly it’s luck based. Furthermore to illustrate more I have only hit 9999 once on freebitco, and post that I have been chasing it for 3 years now, and yet I have not been able to hit it, so you see in the end it all comes down to your luck and not the number of spins.
It might increase the odds, but only very slightly I think because if we look at the most recent lottery for example, there were over 206 million tickets and if we look at the prize winners, the top 10, the vast majority of those winners were by users who held a fairly low amount of tickets.
I would personally spread out my tickets to participate in all of the lotteries instead of dumping them all on one, because I don't think it'll make that much of a difference, in my opinion. I would rather have a tiny shot at winning in 25 lotteries, instead of having a slightly better, but still ultimately tiny shot at winning 1 lottery.
