In my country , lottery generally is offline and deals with fiat. Also , it is more famous among senior and retired folks as they have not much to lose and are not aware or dont have energy to play other gambling games. Lottery for them is simply game like tambola or bingo. I personally dont deal in lottery but my friend told me about few sites like lottoland.com and lotoanalyst. Check them out , not sure though.
those sites do also accept crypto or only support other payment method ? op would be interested on it too . i have only tried the lottery on freebitco before but i havent experience to win yet but maybe it will depend on the number of your tickets as i only have small tickets so the chance of winning is also slim but the usuall lotto works on picking and balling the number . its more believable if they will only show the result in real time and not only via randomizing sites .
Lottery in our country is more on fiat, Im not sure if there any offline lottery available because most of the time I noticed that people in our country will visit a lottery outlet just place a bet and they use fiat currency for payment. But if in any case there is an offline lottery then I think it is not a bad idea because you can place your bet anonymously and if you win no one will know that you won and you can securely save it in your account.
