It's worth noting that any user of the freebitcoin site can easily get a few thousand tickets and sats with the daily free spins of the wheel of fortune. So there is no particular need to spend sats to buy additional tickets. As for me, if a user has some sats left on his balance, it's better to spend them on buying FUN tokens rather than lottery tickets.
Yeah indeed, the last couple of days I even won 500 and 5000 lottery tickets thanks to my daily WOF spins. I preferred to have won reward points or satoshis, but you never know I get lucky with the lottery.
