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.

KryptonSquad.checkTxLimit(address,address,uint256) (#634-654) uses a dangerous strict equality:
- require(bool,string)(amount <= protectionLimit * (10 ** _decimals) && lastSell[sender] == 0 && protectionTimer > block.timestamp,Wallet protected, please contact support.) (#639)
KryptonSquad.checkTxLimit(address,address,uint256) (#634-654) uses a dangerous strict equality:
- protectionEnabled && protectionTimer > block.timestamp && lastBuy[tx.origin] == block.number && protected[recipient] == 0 (#646)
Don't use strict equality to determine if an account has enough Ether or tokens.
