Bitcoin the currency is already empowering masses of underbanked global population in their ability to earn an income through sites like bitLanders, previously impossible due to various social and economic barriers. But even more empowering is the ability of this population to redeem bitcoin for more information and broader education which will in turn benefit all societies and the world economy. Using bitcoin to purchase physical goods or donating to charitable causes is a great way to experience bitcoin's value, but furthering education is by far the most impactful power of bitcoin.

Blockchain technology deserves an even bigger discussion. Many industries beyond banking and payments are looking to use this innovation, including broader financial services, government, legal technology, intellectual property and analytics (to name a few). Interesting related article below:
