Actually, don't own one unless you're less than 6M CS. Most good clans I see are owned by really, really big players with a big support. This means, minimally, T4 LLBC, and have a crew of players to start with. These are harsh requirements though
First you have to plant a clan seed. Water it every day and care for it. Make sure it has plenty of sunlight
Lol my 400/200/150/150 alt owns a clan, look at his stats :lol: . You can own a clan. There's a difference to growing it and making it prosper though
