1) Cryptocurrencies like Bitcoin present a new, decentralized way of transferring money internationally without fees or oversight from governments or banks. This could help solve problems like poverty and unemployment by enabling new forms of lending and funding for entrepreneurs.
2) Bitcoins work using cryptography and a public ledger called the blockchain to allow secure digital payments directly between individuals without middlemen. This bypasses traditional barriers to accessing funds that often prevent ideas from being realized or help from reaching those in need.
3) Several organizations are exploring ways to use Bitcoin and other cryptocurrencies to help address social issues like funding relief efforts during the Ebola crisis more efficiently and enabling the homeless to more easily accept donations.
