Last week, Nepal was hit with a magnitude 7.8 earthquake – the worst in 80 years. More than 4,000 people died, and hundreds more are without food, water or shelter.

Natural disasters shake not just the core of our communities, but also the core of our humanity. Many of us feel a deep-seated need to reach out and help during major catastrophes. But it can sometimes seem overwhelming when the scale is so large, and hard to know how to make a real difference.

Three leaders in the Bitcoin ecosystem – the BitGive Foundation, ChangeTip, and BitPay – have solutions to help:

The BitGive Foundation is running a campaign to raise donations for Medic Mobile, a nonprofit organization that uses mobile technology to improve health-service delivery. Here's a message from the Medic Mobile Team:

"The Medic Mobile team is actively exploring how we can help with local, coordinated relief efforts after the earthquake that devastated Kathmandu on Saturday, April 25th. Our third-largest office is based there and very thankfully all of our teammates are safe. The Bitcoin community has already been so supportive of our efforts in the past and we'd be grateful for that support again. Every donation will go directly to our Nepal office and help as we deploy the right technology. Thank you from our whole team."

ChangeTip is encouraging the Bitcoin community to contribute to the Red Cross via Twitter tips. More than 400 ChangeTip community members contributed to the Red Cross from Sunday to Monday as part of an ongoing, weeklong campaign. The campaign currently exceeds more than $3,200 in micropayments.

BitPay also processes donations for Save the Children, an international relief organization mobilizing humanitarian assistance in Nepal. Save the Children began accepting bitcoin donations last fall after a successful 2013 campaign with the BitGive Foundation to raise funds for the Philippines Typhoon Haiyan relief effort.

How can you help support the people, families, and communities in Nepal? Reach out to more charitable organizations and encourage them to accept bitcoin donations. BitPay charges no (zero percent) transaction fees, and nonprofits receive all (100 percent) of their contributions in their local, fiat currency.
