(Jack Guez/AFP) JTA — Many of Twitter’s cryptocurrency zealots are often notorious trolls, but one particular thought leader stands out from the rest. He happens to be a rabbi. “Twitter people either use it to scream at each other and not be nice, which I don’t like,” says micro-influencer Rabbi Michael Caras, also known as @thebitcoinrabbi. ”I enjoy connecting with my two communities through Twitter, both Jewish Twitter and Bitcoin Twitter.” Caras, a rabbi associated with the Hasidic Chabad-Lubavitch movement, is fascinated by the way that Bitcoin, both the network and the asset, relates to halacha (Jewish law). And since he’s quite vocal about it online, Caras says that strangers slide into his Twitter messages each week to ask for advice and spiritual guidance on the topic.
