My ETH funds were stolen and I am sure I didn't give out or handled carelessly the Mnemonic phrase, JSON file, private key nor the key store. Please I want to know ways by which a cryptocurrency wallet could be hacked.
I heared this case already, and it is scary that eventhough you keep all the necessary things to be private but still you are hacked. Maybe there are sites in which you visited and there the hackers hacked your private informations. It is just my guess.
