I have some NEO at neotracker and someone hacked my account........
So I'm asking you what is the most secure neo wallet to use... thank you.
Neo tracker is actually a good NEO wallet with web interference but looks like you got phised by someone and logged into fake Neotracker wallet with your private key. I suggest you to bookmark sites like these and double check the URL before entering your private key. Neo-Gui wallet is available but I don't recommend it.
