I see a different Bitcoin address. I recommend people visit the site and not use the address random commenters on the internet post. Not saying the parent comment is up to something, sci-hub may have rotated the address for whatever reason. The one I see starts with 14ghuGKD

EDIT: Ah, interestingly, the 1K4t2v address appears on the scihub.cc homepage, but not the donate page that was linked

I thought about not posting it as well. When I did, I double-checked myself twice to make sure I didn't post the wrong one.

Accessing the ip posted in the article it shows the bitcoin address posted by the OP.

I even switch over to https to make sure the request is not modified.

>switching to https

They don't even have a valid certificate for that domain.

BUT interestingly, on a US (DO NYC) server or my house (US/Comcast):

  $ curl http://sci-hub.cc/donate
  <p>Please donate to Bitcoin: 14ghuGKDAPdEcUQN4zuzGwBUrhQgACwAyA</p>%

however, on a French (OVH) server:

  $ curl http://sci-hub.cc/donate
  <!DOCTYPE html>
  <html>
      <head>
  {cut for brevity, a fair amount of HTML here}
  <p>Please send donations to bitcoin wallet: 1K4t2vSBSS2xFjZ6PofYnbgZewjeqbG1TM</p>
  {more HTML}

DNS reports that the domain's IP is 31.184.194.81 from all tested locations. I get the HTML page with the 1K4t address over tor as well

Tested from US university IP, I also get the 1K4t wallet address. Maybe a caching issue with the CDN (assuming they use one)?

Which university? I tried from the University of Washington and got the 14gh address

I am getting the same thing. Midwest US ISP is getting 14ghu and french (free.fr) server is getting 1K4t2v

Appears to be some sort of caching issue. Archive.org shows sci-hub.org with 1K4t2v from 2015[0]

Is it legal to donate?

I think that asking a question like this says a lot about your country.
