"We believe long-term supply and demand trends support further industry growth, the potential for further compression in price volatility, and a possible role as portfolio diversifiers," according to the WFII Global Investment Strategy Team.The bank considers digital assets as an alternative investment for "qualified" investors through a professionally managed funds. Risks include additional regulation, operational risks with executing transactions, and periods of "persistently high volatility."Indeed, volatility has been the theme of today's trading, with bitcoin slumping to just under $30K, then recovering some to trade at $38.6K
