$green [Green Chart] Token

Green.buyBackAndBurn(uint256) (#1381-1398) sends eth to arbitrary user
Dangerous calls:

Green.rand() (#1194-1210) uses a dangerous strict equality:
- randNumber == 0 (#1204)
Don't use strict equality to determine if an account has enough Ether or tokens.

Green.updateBotFees(uint256) (#1170-1173) contains a tautology or contradiction:
- require(bool,string)(percent >= 0 && percent <= 100,must be between 0 and 100) (#1171)

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.

Green._transfer(address,address,uint256) (#1212-1362) performs a multiplication on the result of a division:
-buyBackBalance = (afterSwap.sub(buyBackBalance)).mul(buyBackFee).div(totalSellFees) (#1278)
-buybackAmount = buyBackBalance.mul(buybackpercent).div(100) (#1303)
Consider ordering multiplication before division.
