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.
If you can do it on your own, then its better to do that and youre correct about your security. If you ask someone to buy for you, then you might need to pat the fees which can cost you more. I would only buy using my bitcoin if Im sure about my security.
he said he can do it on its own but his problem is that his afraid to buy ticket online using btc because he thinks that he can be track if ever he won . @robelneo you shouldnt worry if you buy on an offcial store because they wont care at all even if you win . they wouldnt trace you . but if your still worrying you can try using a mixing service so that no one can trace your transactions or you can use other privacy cryptos if ever they support it .
