The use of a CCL does not mean that you do not have the copyright on your work anymore. Instead, a CCL helps the creator of a copyrighted work to retain some of his rights stemming from copyright while making available to the public his work and ensures that he gets the credits for his work.
As the creator of a copyrighted work, you have the flexibility to choose which rights will be reserved by choosing among the different types of licences. However, once you use a CCL, you cannot prevent others from copying and distributing your work. Hence, if you wish to reserve all of your rights under copyright law, then you should not use a CCL.
