report
Token seems to be (relatively) fine. It still become a scam, but probability is moderate.

StrikeX.transferTokens(uint256) (contracts/StrikeX.sol#321-338) sends eth to arbitrary user
Dangerous calls:
- _teamWallet.transfer(teamBNB) (contracts/StrikeX.sol#334)
- _buybackWallet.transfer(buybackBNB) (contracts/StrikeX.sol#337)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.
