Since the very beginning Sci-Hub is supported by donations from website users. I do not have other sources: there are no advertisements, mecenate support or government funding although there should be. All information on Sci-Hub is free to access. Users keep the website up and running by donating small sums.
Donate in a decentralized way
Sci-Hub accepts donations in cryptocurrencies: a hi-tech, decentralized version of money.

To donate by Bitcoin use the new address:

‐ I do not know how to use or afraid to use cryptocurrencies, do you have other options to donate?
‐ Using cryptocurrency today is very easy, to get started, just install any popular crypto wallet on your mobile phone. At the moment Sci-Hub does not have other options to donate because of legal complications, but these options will be added in future - keep watching for updates!
