It is precisely said, no one asks for the keys, in what fraud I do not understand?
In order to get the fork tokens, you need to prove that the original wallet belongs to you. That's why they ask you to insert your private key. However, this is used by scammers
I have noticed a lot of such projects that are asking for the key to the wallet, and a lot of complaints from people who are trying to prove without proof that the project is scammed.
