DEX [dexIRA] Token

DexIRA.swapAndLiquify(uint256) (#1973-2027) sends eth to arbitrary user
Dangerous calls:
- (success,None) = address(buyBackWallet).call{value: buyBackBalance}() (#2021)
DexIRA.addLiquidity(uint256,uint256) (#2047-2060) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,liquidityWallet,block.timestamp) (#2052-2059)
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.

DexIRA._transfer(address,address,uint256) (#1815-1969) uses a dangerous strict equality:
- _holderLastSellDate[to] == block.timestamp (#1849)
DexIRA.getHolderSellFactor(address) (#1623-1640) uses a dangerous strict equality:
- _holderLastSellDate[holder] == 0 (#1629)
Don't use strict equality to determine if an account has enough Ether or tokens.

DexIRA._transfer(address,address,uint256) (#1815-1969) performs a multiplication on the result of a division:

-fees = fees.mul(getHolderSellFactor(from)).div(100) (#1946)
DexIRA._transfer(address,address,uint256) (#1815-1969) performs a multiplication on the result of a division:

Consider ordering multiplication before division.
