I lost some $ and some token on my wallet, can anyone help me return my assets?
Which wallet you were using? MEW?
yes, I use My Etherwallet and verify it with Private Key? I think it will be safe

You have been a victim of phishing and there's no need to use that wallet anymore with the same private key. And crypto transactions can't be undone so when you have sent it to someone, there's no way to recover it. And as the hacker stole your tokens the only way to recover it if he's too good and will volunteer to return those tokens that he stole from you.
Well, thanks for the advice, I will not use that wallet for the future. then if I create a new Wallet is there anything I need to do to prevent this from happening again?
