Once cryptocurrencies are withdrawn to the specific address of a recipient, the assets are transferred to the address and owned by the address holder. It is recommended to familiarize yourself with some of the most commonly observed crypto scams to help protect yourself and your investments.
I. Identity Scams
1. Scammers impersonate the officials of the platform or public security agents to defraud users.
Scam: You are contacted by by someone claiming to be a security or support center staff of a trading platform and are requested to cooperate with a security investigation, freezing your account on the grounds that they detected a money laundering risk from on your account (such as suspected of money or crypto laundering transactions). By taking advantage of your panic, scammers lure you into clicking fake URL links in an attempt to steal your log in details or make a deposit or transfer to a fraudulent account.
Methods:
1. Scammers will add you on social platforms such as Twitter and Telegram and request your E-mail address to send a link or QR code before enticing you into entering your account information, log in to your AscendEX or bank account, and steal your account information and assets.
2. They may ask you to download meeting software, Apps for screen sharing, or remote control of your phone. This attack provides them with access to your OTPs or Google authentication codes when verifying your identity, thus stealing your account information and assets.
3. They may lure you into depositing and withdrawing to a designated address they claim is a “Security Account”, or they may demand you transfer your assets to a specified bank card to “unfreeze” your account.
4. E-mail or SMS phishing: Scammers will attempt to convince you to withdraw your assets to a fake address by sending a clone SMS or Email that looks as if it came from a trading platform.

Under no circumstances will AscendEX, or its staff, contact you on the grounds that there is a risk of money-laundering on your account, nor will we ask for any security passwords, verification information, or request you to download a third-party screen sharing software.
