No, I will not buy if I won the lottery people where I bought online can easily trace me as their winner, it's better that you buy your own ticket online because your privacy is safe, there are people here that offer people for their service and that is buying a ticket for them for a small fee, but what if they record your ticket, they will know exactly that you've won the jackpot.
It could be something to consider and you are just worrying what will happen when you win. But I don't think that it will ask your personal details when buying ticket cause it probably is happening in the time of claiming the rewards. So being traceable as you think is really that far.
Exactly, it is not happened, it is safe just like in other sites we use crypto currency. Even i will not advice of it that buy lottery with bitcoin, because bitcoin is more precious than lottery, but perhaps it is safe way to buy lottery and if you won then definitely you will get your money safely.
If this is doable, I just hope gamblers that are buying these lottery tickets get their rewards or prices when they won.
There are a lot of sites that are not legitimate and they might pay using their Bitcoin but they might be scammed. There are a lot of legitimate platforms and offline places where you can buy lottery tickets, you can just buy there. Even if they are not accepting Bitcoin, that is fine as long as you can still place your money on the lottery. If I am you, I'll just keep my Btcs since it may pump in the next weeks.
