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.
