possible victim of non-spendable scam A bitcoin trader opened a blockchain wallet for me and then sent me my profit but it is non-spendable. I know they can no longer get into my account because I changed the password and I have two-step verification. And I don't see them created passphrase, that means no private key was stolen?

Can they still access to my wallet?
I'm the simlar situation as below thread, but how do I know private key was taken?

Yea they can still access your wallet. 

When the scammer created the wallet, they will have written down the mnemonic seed phrase for the wallet. With this seed phrase, they can recreate your wallet using some other software, since the seed phrase will allow them to derive all of the same addresses. They do not need the password to do this, and changing the password will not stop them either. 

Think of it like this: you have a secret (the seed phrase) hidden in a box, and your password is the lock on the box that protects that secret. If the scammer steals the secret before you lock the box, they won’t need your password. They already have the secret! 

So, the best thing to do is just never use that wallet (or seed phrase) again, and stop talking with the scammer.
