ICNV2.distributeFee() (contracts/ICNV2.sol#303-333) sends eth to arbitrary user
Dangerous calls:
- (sent) = address(_taxFeeWallet).call{gas: 30000,value: amountBNB}() (contracts/ICNV2.sol#324-327)
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.
Contract ownership is not renounced (belongs to a wallet)
Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

Contract name (I-COIN) contains non-alphanumeric characters.
Not a direct threat, but may indicate unreliable intentions of developer. Non-alphanumeric chars (,.;!#*&") are extremely rare among low risk tokens.

Low level call in ICNV2.distributeFee() (contracts/ICNV2.sol#303-333):
- (sent) = address(_taxFeeWallet).call{gas: 30000,value: amountBNB}() (contracts/ICNV2.sol#324-327)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
