I have only seen a winner in the American lottery but have not seen anyone won all the online lottery around as most of the promotions and announcements of winners may be based on false and in most cases doctored picture and videos. I can only believe in lottery when I can verify the prize winner with physical evidence.
^ There must be a reason why they don't disclose to anyone if they have won from the lottery online using crypto. It is very simple just because of the privacy and the reason they hide their identity. Even if you will win the jackpot in your local loterry, they will never disclose your identity or even mentioning your name not unless if you want exposure. The problem with the lottery is the chances of winning are very small then if you know how to verify the result of the crypto lottery, there could be a true winner.
It would be just dumb that you would really be making out some exposure after you have won some jackpot in lottery because this would for sure put you in danger because there would be lots who would go after you
since your identity had already been exposed thats why it is just too dumb for you to have this kind of decision and thats why it isnt surprising that there are lots of instances that winners could be known.
When it comes to fairness then we could somewhat able to verify things out but not all the time because there are instances where lotteries were rigged.
