Transfer of tokens without enabling trade.
The trading needs to be enabled by the owner in order for regular users to transfer tokens. On the contrary, the owner can authorize addresses manually and those addresses will be able to trade tokens. This functionality can be exploited in the following way, For example, there is a presale and the wallets used for the presale can be authorized by the owner. All the tokens obtained can be consolidated into a final wallet address and facilitate trading and selling of the acquired tokens, the last wallet address can be authorized.
