For anyone who's interested in cryptocurrency in general and bitcoin in particular, you have to watch Vinay Gupta (@hexayurt on Steemit) on the FutureRant podcast Bitcoin & TheDAO.
I will write a blog post on how entertaining and enlightening it is to listen to Vinay as a guest on various cryptocurrency podcasts blow holes large enough for a tank to drive through on the closely held precepts of cryptocurrency and its affect on society and governments.
You may not agree with him but he brings up issues that don't get airtime otherwise in the cryptocurrency community.
