騙局：無法換回代幣

最近我從 PancakeSwap 買了一個代幣。看起來像是被騙了——它是新的，只有買入操作，沒有賣出操作。而且我也不能換回來。

我正在提供它的契約原始碼，如果有人解釋為什麼它不能出售，我會很高興：

我將不勝感激任何幫助將其換回並返還我的投資！

轉移中的這一行是禁止轉移：

def transfer(address _to, uint256 _value): # not payable
 ...
 if unknown1ee59f20Address == _to:
     revert with 0, 'Please wait'

如果你讀出unknown1ee59f20Address（儲存槽 6），它會顯示一個地址：682b9056b61a5087e2373a6ee6a7d3000752b46c: PancakeSwap V2: BUSD-STXC ( https://bscscan.com/address/682b9056b61a5087e2373a6ee6a7d3000752b46c#code )

所以合約主動禁止向pancake LP轉賬。

此地址可由所有者設置：

def unknown81f4f399(addr _param1): # not payable
 require calldata.size - 4 >= 32
 require caller == owner
 unknown1ee59f20Address = _param1

從“請稍候”消息來看，此令牌很可能會在一段時間後啟用傳輸（或者它只是一塊地毯）。無論如何，我會遠離禁止以任何形式轉移的代幣。
