H.C. Wainwright analyst Kevin Dede lowered his price target for Riot Blockchain to $4 from $10 but keeps a Buy rating on the shares. The "ugly ramifications" of Riot's CEO departure in early September compounded by an increasingly difficult bitcoin mining and pricing environment have temporarily upended the company's fundamental development, Dede tells investors in a research note partially titled "Industry Dynamics Strain a Temporarily Fractured Business Model." The analyst, however, sees a "silver lining" in Riot's focus and commitment to building its cryptocurrency trading platform, RiotX. Dede remains bullish on bitcoin's "eventuality in fulfilling its utilitarian currency potential."
