"When you shop for bitcoin service providers, keep an eye on where they come from and who is involved in the project. Many startups in this space are VC-funded companies and have to play ball in order to have an “exit”. They might offer really pretty web design, but not the prettiest politics.
Today, we are stating again for the record that we feel bitcoin’s fungibility is sacred. A $20 USD bill might be used to snort drugs before it comes to you, but that doesn’t make it worth less than $20 USD. All bitcoins should be the same. They do not become tainted by who owns them or what business they are in. We do not track or care where you send your bitcoins, or how they came into your possession."
