CoinToken._canTransfer(address,address,uint256) (#431-456) uses a dangerous strict equality:
- start == 0 (#438)
CoinToken._canTransfer(address,address,uint256) (#431-456) uses a dangerous strict equality:
- start == 0 (#445)
Don't use strict equality to determine if an account has enough Ether or tokens.

CoinToken._canTransfer(address,address,uint256) (#431-456) uses timestamp for comparisons
Dangerous comparisons:
- start == 0 (#438)
- start == 0 (#445)
- (block.timestamp - start) >= THRESHOLD (#446)
- (block.timestamp - lastBuy[_to]) < DELAY (#452)
Avoid relying on block.timestamp.

StandardToken.transfer(address,uint256) (#138-169) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#144)
StandardToken.transferFrom(address,address,uint256) (#171-202) compares to a boolean constant:
-require(bool)(tokenBlacklist[msg.sender] == false) (#176)
Remove the equality to the boolean constant.
