There are several websites that allow you to donate Bitcoin to charities and nonprofits. One such website is The Giving Block, which provides a platform for nonprofits to accept cryptocurrency donations. They offer a quick and easy way to create a donation button for your website that displays a QR code and Bitcoin address for payment. Another option is Givepact, which allows you to receive crypto donations on average 10455 versus 128 for cash. They offer a donor prescreening process, free and simple onboarding, and free education courses. You can also donate Bitcoin directly to charities, such as Save the Children, which accepts crypto donations and provides an option to leave a comment in the Donation notes field.
