*Who benefits most $$$ from hidden services, DNM operators. Bitcoin donations to Tor devs to further hidden service development = $0. *
Also, it's important to note that Tor currently doesn't have funding for improving the security of hidden services. If you are interested in funding hidden services research and development, please get in touch with us. We hope to find time to organize a crowdfunding campaign to acquire independent and focused hidden service funding.
