BDKing._transfer(address,address,uint256) (#881-1064) uses a dangerous strict equality:
- time == 0 || time + 5184000 > block.timestamp (#901)
BDKing._transfer(address,address,uint256) (#881-1064) uses a dangerous strict equality:
- require(bool,string)(userLiquidity == 0 && lastInPoolTime[to] == 0 && presaleTime[to] == 0,ERC20: do not meet the purchase conditions) (#984)
BDKing.mining(uint256) (#1066-1127) uses a dangerous strict equality:
- liquidity == 0 (#1098)
Don't use strict equality to determine if an account has enough Ether or tokens.

BDKing._mineRate() (#1171-1201) contains a tautology or contradiction:
- 0 <= totalTokenMine && totalTokenMine <= 500000000 * 10 ** 6 (#1173)
Fix the incorrect comparison by changing the value type or the comparison.

Not a direct threat, but may indicate unreliable intentions of developer. Widespread names (e.g. Elon, King, Moon, Doge) are common among meme-tokens and scams. The allow to gain free hype and attract unexperienced investors.

BDKing.mining(uint256) (#1066-1127) performs a multiplication on the result of a division:
-tokenNum = totalTokenInPool.mul(_mineRate()).mul(dayNum).div(10000) (#1076)
-mine = tokenNum.mul(liquidity).div(totalLiquidity) (#1102)
Consider ordering multiplication before division.

BDKing.mining(uint256).dividends (#1108) is a local variable never initialized
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.

BDKing.setSendLeft(uint256) (#830-832) should emit an event for:
- sendLeft = left (#831)
Emit an event for critical parameter changes.

BDKing.setExchangeAddress(address).exchangeAdd (#834) lacks a zero-check on :
- exchangeAddress = exchangeAdd (#835)
BDKing.setPancakeRouter(address).routerAdd (#838) lacks a zero-check on :
- pancakeRouter = routerAdd (#839)
BDKing.setPresaleAddress(address).presaleAdd (#842) lacks a zero-check on :
- presaleAddress = presaleAdd (#843)
BDKing.setFundAddress(address).fundAdd (#846) lacks a zero-check on :
- fundAddress = fundAdd (#847)
Check that the address is not zero.

BDKing.mining(uint256) (#1066-1127) has external calls inside a loop: liquidity = ERC20(exchangeAddress).balanceOf(user) (#1096)
Favor pull over push strategy for external calls.

BDKing._transfer(address,address,uint256) (#881-1064) uses timestamp for comparisons
Dangerous comparisons:
- lastTime != 0 && lastState[lastSender] == 0 (#889)
- time == 0 || time + 5184000 > block.timestamp (#901)
- require(bool,string)(lastInPoolTime[to] != 0 && lastInPoolTime[to] + 5184000 < block.timestamp,Lock time is not up) (#971)
- require(bool,string)(userLiquidity == 0 && lastInPoolTime[to] == 0 && presaleTime[to] == 0,ERC20: do not meet the purchase conditions) (#984)
- time_scope_1 > 0 (#1023)
- require(bool,string)(time_scope_1 + 14400 > block.timestamp || time_scope_1 + 5184000 < block.timestamp,ERC20: Time exceed) (#1025)
- require(bool,string)(time2 + 14400 > block.timestamp,ERC20: Time exceed) (#1039)
- require(bool,string)(lastInPoolTime[from] != 0 && lastInPoolTime[from] + 5184000 < block.timestamp,You must first add liquidity pool) (#1060)
BDKing.mining(uint256) (#1066-1127) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)((block.timestamp / 86400) - (lastSettleTime / 86400) >= 1 && dayNum > 0,Can only be settled once a day) (#1068)
Avoid relying on block.timestamp.
