The Izz al-Din al-Qassam Brigades, the "military wing" of Hamas, put out a call for donations though Bitcoin.
They posted a Quranic verse on social media about the importance of charity, and added, "Reserve yourself a share in support of the resistance through the Bitcoin donation link."
At the link they have an animated video describing how to donate with Bitcoin.
I assume that Israel has hacked the site and can see the "progressives" who are clicking to donate.
