The Secrets of Bill Cipher

Why is Bill's Name Bill?

I believe that Bill Cipher's first name is Bill because he is on the back of the dollar bill as shown below.

The Bill Symbols

All the Bill wheel symbols

The Bill symbols are symbols that mean the names of the Gravity Falls characters. Do some of you remember when in "Dreamscaperers" Bill said to Dipper, Mabel, and Soos, "Question mark, shooting star, pine tree. I had a hunch a might bump into you!" Well Bill was calling them by their Bill symbol names. Soos is "question mark" because of the question mark on his shirt, Mabel is "shooting star" because one of the sweaters she wore had a shooting star on it, and Dipper is "pine tree" because in "Tourist Trapped", Stan let Mabel and Dipper get something at the gift shop for free and Dipper got a hat with a pine tree on it to replace the hat he had with a star on it. Here are the possibilities or really what the symbols mean.
Question Mark: Soos because of the question mark on his shirt
Ice Bag: Wendy because she started going out with Robbie because Dipper didn't have the ice bag
Fish like symbol: Stanford Pines because the fish like symbol is on his fez

Pine Tree: Dipper Pines because his hat has a pine tree on it
Star with an eye: Gideon Charles Gleeful a.k.a. 'Lil Gideon because on the top of the Tent of Telepathy the star with an eye is there and also the star with an eye is Gideon's icon
6-fingered hand: Fiddleford H. McGucket a.k.a. Old Man McGucket because he used to have 6 fingers and he wrote the three books.
Opposite llama hair: Pacifica Northwest Mabel had a llama hair sweater in Headhunters and The Hand That Rocks the Mabel but this llama is mirrored and Mabel and Pacifica are enemies=oppisites vise versa. You see where I'm going with this?
Shooting Star: Mabel Pines because one of the first sweaters she was ever seen wearing had a shooting star on it.
Heart with stitching: Robbie V. because on his sweater it has a heart with stitching on it.
Glasses: Stanly because when Stanely left the Mystery Shack he left his glasses in his room.
