I've been thinking of using bitcoin to help individuals especially those womens (I mean a plain housewife) who wanted to have additional income. Then suddenly this idea of microfinance gave me such an interest.
In many countries the evolve of microfinance grows fast
 In fact, the government is really looking on it as a big help to the economy. Since banking institutions cannot offer such loans to least people, this microfinance open up a door and lend ordinary people with such low interest to help them start their own business.
If bitcoin can be use by a microfinace institutions as a new source of fund I think the goal of poverty eradication of many governments can be solve.
