This is frustrating. Yes, support the mangaka. The first volume will not show up until september the earliest. Scanlations are always better than official. Sure, I have the raw and read it up to date. Someone like me will be more than happy to buy the raw and the official translations. Whether you read scanlation or not. has nothing to do with supporting the mangaka, the publisher (Kodansha), and the official copy right holder who will translate it (sevenseas).
I always read scanlations first, then purchase a digital raw version, and finally in physical form. After that, the digital official translated version. Since I am multi-lingual, I sometimes will buy other language versions as long as they are official.
This is the equivalent of music. You don't make money selling music in their digital form, but by selling the music as cheap as possible, you basically invite anyone to buy the mp3 version. The big money for musicians comes when they start touring, and because the songs are now known by the fans, they will attend the show, including those who are first timers. That is how you hook people to see you live, and will pay big money to watch you.
