<p>No, it's a bad idea to run bitcoin over tor if your striving for anonymity. Here is a <a href="http://arxiv.org/abs/1410.6079" rel="nofollow">paper</a> detailing the vulnerability. </p>

  <p>While Bitcoin provides some level of anonymity (or rather pseudonymity) by encouraging the users to have any number of random-looking Bitcoin addresses, recent research shows that this level of anonymity is rather low. This encourages users to connect to the Bitcoin network through anonymizers like Tor and motivates development of default Tor functionality for popular mobile SPV clients. In this paper we show that combining Tor and Bitcoin creates an attack vector for the deterministic and stealthy man-in-the-middle attacks. A low-resource attacker can gain full control of information flows between all users who chose to use Bitcoin over Tor. In particular the attacker can link together user's transactions regardless of pseudonyms used, control which Bitcoin blocks and transactions are relayed to the user and can delay or discard user's transactions and blocks. In collusion with a powerful miner double-spending attacks become possible and a totally virtual Bitcoin reality can be created for such set of users.</p>

<p>You should install software, that will inform you that https:// is changed into http:// (or does not let the situation). Few weeks ago 300 btc was stolen with the method from Tor users.</p>
