We need a logo design for a new company called "Bitwis", which stands for "Bitcoin Wisdom". The goal of our company is to create a value proposition for users of bitcoin in a fast emerging digital currency ecosystem. We need a logo that is simple, unique and meaningful. Ideally, through the logo we want to convey the message that our company is contributing to the organic growth of the Bitcoin ecosystem by fostering real user adoption. The logo should *NOT* contain the Bitcoin symbol (https://en.bitcoin.it/wiki/Bitcoin_symbol). A preferred design is abstract and symbolic, something like the logo in the attachment.
