BullDogeChain.sendBNB(address,uint256) (#502-507) sends eth to arbitrary user
Dangerous calls:
- (success) = recipient.call{value: amount}() (#505)
Ensure that an arbitrary user cannot withdraw unauthorized funds.
Additional information: link
BullDogeChain.claimStuckTokens(address) (#487-496) ignores return value by ERC20token.transfer(msg.sender,balance) (#495)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

BullDogeChain._transfer(address,address,uint256) (#539-613) uses a dangerous strict equality:
- launchedAt == 0 && to == (uniswapV2Pair) (#553)
Don't use strict equality to determine if an account has enough Ether or tokens.

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.
Combination 2: Unchecked transfer + 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.

BullDogeChain._transfer(address,address,uint256) (#539-613) uses timestamp for comparisons
Dangerous comparisons:
- launchedAt == 0 && to == (uniswapV2Pair) (#553)
- launchedAt + 30 > block.timestamp (#555)
- require(bool,string)(block.timestamp - lastTransactionTime[from] >= 15,You need to wait 15 seconds before selling at launch) (#560)
- launchedAt > 0 (#563)
Avoid relying on block.timestamp.

Pragma version0.8.16 (#7) necessitates a version too recent to be trusted. Consider deploying with 0.6.12/0.7.6/0.8.7
solc-0.8.16 is not recommended for deployment
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in BullDogeChain.sendBNB(address,uint256) (#502-507):
- (success) = recipient.call{value: amount}() (#505)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence

Contract has 2% buy tax and 2% sell tax.
Taxes are low but contract ownership is not renounced. Token has a high risk of becoming a honeypot.
Average 30d PancakeSwap liquidity is low.
Token is deployed only at one blockchain
Token has only one trading pair
Young tokens have high risks of scam / price dump / death

Token is relatively young, but twitter if very old (probably it's fake).
