(MENAFN - Asia Times) BlackRock, the world's biggest investment firm, has 'started to dabble a bit' in crypto investment. In an interview with CNBC's Squawk Box on Wednesday, Rick Rieder, the American firm's chief investment officer, hinted that it had already made crypto investments and said many investors were keen to find 'places that appreciate under the assumption that inflation moves higher as debts are building.' He added, 'Holding some portion of what you hold in cash in things like crypto seems to make some sense to me, but I wouldn't espouse a certain allocation or target holding. My sense is the technology has evolved and the regulations have evolved to the point where a number of people find it should be part of the portfolio.'
