(Reuters) -BlackRock recommends that interested investors consider allocating as much as 2% of their portfolio to bitcoin, the world's largest cryptocurrency, the giant asset manager said in a report on Thursday.

"We see a case for investors with suitable governance and risk tolerance to include bitcoin in a multi-asset portfolio," a team of four senior BlackRock executives including Samara Cohen, chief investment officer of ETFs and Paul Henderson, senior portfolio strategist of BlackRock Investment Institute, said in the short report.
