Blockchainchargeback[removed by editor]" is a typical scam company. First, they ask for $10,000 to help you get your crypto assets back, disguised as a legitimate transaction with a contract.
Then they falsely report that they have [removed by editor]ed the crypto assets.<br />
To transfer the [removed by editor]ed crypto assets, they ask you to open an account on "Blockchain[removed by editor]" and then transfer 1BTC to the account.<br />
It is unclear if they are in collusion with Blockchain[removed by editor], but once the money is transferred, the 1BTC disappears and they claim that they cannot confirm the transfer.<br />
Never trust them. Never trust them, and if you are a victim, sue them in the international judicial process.
The platform has restrictions on all withdrawals and does not allow withdrawals unless they are manually authorized by the operator. In other words, there is no intention to allow withdrawals from the beginning.
When you request a withdrawal, they ask you to pay a certain percentage of your total assets or a fixed amount in US dollars within a week as a special fee. And the additional fees are exorbitant.<br />
If you refuse, they will freeze your account and ask you to pay a fee to unfreeze it.
