One of the most asked questions in the bitcoin 'verse is the one of "Which exchanges? Where to buy?" According to the FAQ these questions are deemed as off-topic, however, it would provide value to the community if we could offer a generice answer to it.
We already have a question that tries to address this topic in a generic way: How do you obtain bitcoin?
I have created a bounty to update answers to this question to cover: What are the ways to acquire bitcoins? Is there a website that gives an extensive overview of the operating exchanges (As in customer satisfaction, offered features, traded currencies, fee schedule, location and so forth.)?
Should this effort produce an excellent answer we could consolidate the existing duplicate questions and relay any future questions to it.
