This morning, February 15th, another Coinbase employee wrote on Reddit that “the unexpected charges are originating outside of our control, and are related to charges from previous purchases.” The charges are in the process of being refunded, the employee wrote, although he did not say whether resulting overdraft charges would also be refunded. “We are running joint investigations with all parties involved, and will provide updates as we receive them,” he wrote. Pete Kingree, a Coinbase user in Virginia, provided a screenshot of what he said were unauthorized charges to Coinbase totaling $931 with an additional $7.45 in bank fees. “I am writing the Coinbase CEO, OCC, Barbara Comstock (my representative), and the Governor of Virginia,” he said in an email.
