There's already a thread about this paper here. Judging by the lack of responses, nobody much cares. I suppose I should care, since my hidden service is one of the ones listed, and I'm a little concerned that there were only 38 others reachable; I figured there'd be a lot more. Undecided But apart from that, I'm not really worried.

Well there is already discussion done before in the thread, and i do not understand why it is not a good idea at all.

TL;DR: It is possible for an attacker to cause Tor exit nodes to be banned from the Bitcoin network, forcing Bitcoin nodes running over Tor to connect using the attacker's exit node, giving the attacker complete control over that node's connections (except connections to hidden services). Though, a network split is of course impossible as long as a single hidden service has a good connection to the outside or miners relay blocks directly to at least one hidden service.

Basically, if you're running Bitcoin over Tor, you may end up relying on hidden service nodes more than you expected (which is slightly worrying given how surprisingly few hidden service nodes seem to be reachable).

i have started with bitcoin over a month ago and in this one month i have seen 4-5 posts about people losing their hard earned bitcoins because of using TOR. i just read a new post yesterday on reddit about a guy who lost 1.3 btc, and he was using TOR and worst of all he didn't have 2FA enabled!

That sounds like a separate security issue.

No one can tamper with a signed TX once its done (transaction malleability does not and cannot change outputs only tx hash/id).
