As you can see there are so many airdrops and bounties outside,
i know that there are so many scammers but my question was how they managed to make a transcation from my wallet even though they dont have my private key ?
This is very weird because I haven't seen it happened before, there is no possible way they could have made a transaction from you wallet when they don't have access to your private key, maybe in the course of the airdrop, they sent you a trojan and you never knew about it, but this trojan entered into your computer monitoring all the activities you were carrying out and maybe save your private key and sent it to the hacker when you never knew, this is why we need to be careful the link we click on.
The only thing that I can also think on how this hacker will be able to access your wallet without your private key provided, this is really getting
worse, it's a big awareness that needed to look upon, the danger of following and participating with airdrops, it should be study and make
sure you know what you are doing.
