There are quite many misconceptions that appear about the Dragon City hack activation key. Some people will tell you that this is a key that would activate the hack. These individuals believe that the key was included in order to minimize hack usage. Others will say that there is no such thing as an activation key and that every single site that promises to deliver a working hack only after you receive such a serial number is just a scam attempt. The people in the second category are completely correct.
You should only trust hacks for Dragon City like on New Online Game Hacks. If there is any mention of an activation key, it is better to just not use the services of that particular site that you are on. There is a huge possibility that you are looking at a scam attempt. In this case the activation key that you receive will never work and you definitely lose money in the process as you are asked to pay for the serial key that would be necessary. Do not fall victim to scammers and stay cautious. Make sure that the authority of the site you are on is as high as possible before you even consider downloading something.
