The accounts of Clash royale they are constantly being sold by users, for those who prefer to pay than start from scratch.
Some of these are quite advanced and are often unique.
But like all internet transactions you must be aware not to pay for something that you do not yet have or do not trust any place where they can be offered.
Nor offer personal data or any other account you have.
You must make sure that the account they sell you is not banned in some way or hacked.
But if all this seems difficult to do or you simply do not have the resources to buy an account, there are also different web pages that give away accounts of users who no longer use the game.
Many times these accounts are real and you can obtain them without problems, while on the other hand sometimes these generators give you accounts that have already been claimed or are suspended.
Whichever option you choose, you should always be cautious, but on the other hand if you want to sell or give away your account.
Keep in mind that you will no longer have access to this, as well as you will lose all the advances and your username that you will not be able to use in any other game of Clash royale.
Finally, remember to unlink your account with social networks in case you want to sell it so that this user does not have any access to your personal data.
