It's not a good idea to mention your exchange, or the fact that you're sending direct to an SR address. If you're buying coins under your real identity and you don't send them through a mixing service, that's a security threat. All bitcoin transactions are recorded in the block chain. If someone can identify that bitcoin address as belonging to an SR account, they can link it back to you. If you haven't transferred coins to your SR account yet, you should send them through a mixing service. If you have already transferred coins to your SR account, I suggest you delete this thread. gpg: key A8100891: public key "synthex <synthex@tormail.org>" imported gpg: Total number processed: 1 gpg:       imported: 1 (RSA: 1) Your key is valid.
