An anonymous reader shares a report: The tumble in Cryptocurrencies that erased nearly $500 billion of market value over the past month could get a lot worse, according to Goldman Sachs Group's global head of investment research.

While he didn't posit a timeframe for losses in existing coins, he said recent price swings indicated a bubble and that the tendency for different tokens to move in lockstep wasn't rational for a "few-winners-take-most" market. "The high correlation between the different cryptocurrencies worries me," Strongin said. "Because of the lack of intrinsic value, the currencies that don't survive will most likely trade to zero."
