Elizabeth Rossiello talks about how she went from being a credit ratings analyst for microfinance investors to heading up an "international mobile money" company for sub-Saharan Africa that uses Bitcoin's rails. Along the way she reveals how convoluted, expensive and unreliable the movement of money into and out of Africa can be -- many people sending money in envelopes via regional buses and even traditional banks having to send money from Africa to Asia via North America. With BitPesa's fast and inexpensive international solution, companies are opening up new markets and people sending remittances no longer have to pay exorbitant charges.
