Most likely your account is compromised by using the scam website in your profile name history. I would avoid trading at all until you secure your account.

Your account was phished / hijacked. Follow steps 1-6 to secure your account:

1. Scan for malware https://www.malwarebytes.com/

2. Check that the email and phone number on the Steam account are still yours.

3. Deauthorize all other devices https://steamhost.cn/twofactor/manage

4. Change passwords from a trusted/clean device.

5. Generate new backup codes for your Mobile App https://steamhost.cn/twofactor/manage

6. Revoke the API key https://steamhost.cn/steamcommunity_com/dev/apikey (there should be nothing in the APIKEY)

Steam will NOT return lost funds or Items.
