How to get a shorter account name?

Shorter names are considered premium and can only be obtained by bidding. To win you need to have the highest overall bid for 24 consecutive hours, so at most one per day is won. If you have a name with a shorter name, you can create a collection with the same name. For example, if you want to create a myname.xyz name you need to own the xyz - premium name.
