John Mueller Google Webmaster, announced that Google will transfer all Blogger blogs from the blogspot.com domain to the new domain googleblog.com who considers Google a more formal. When we asked John Mueller why! He said: The reason behind this is to help users understand that administered these codes and are powered by Google. And began the transfer process started from webmasters codes of Google, which is now on this form https://webmasters.googleblog.com. And the base address will be transferred using 301 redirect to the new address process. And Google plans to transfer all blogs to the new address googleblog.com start from oldest to newest. Said John Mueller, "The title of the old Entries will be redirected to the new domain, so your articles links will be as it is and will not change." However, RSS feeds and comments will not be forwarded, you will need to re-subscribe to those services separately. So I advise you to buy a particular domain and linking him to Blogger.
