Bitcoin prices are rising fast, and Fortune's Robert Hackett argues the cryptocurrency is approaching bubble territory. CoinShare's Meltem Demirors says otherwise. But the two agree on one thing: more and more investors are turning to cryptocurrency as a means of diversifying their portfolios.
Also in this episode of Brainstorm, hosts Brian O'Keefe and Michal Lev-Ram ask what happened to blockchain, and wonder if anyone has managed to find a practical way to use cryptocurrency as a payment tool.
Finally, Ripple's Brad Garlinghouse joins the show to discuss how U.S. regulation is hindering his company, and explain why China seems primed to dominate digital currency markets.
