Just to be clear, according to the article,
"The Macro Opportunities Fund may seek investment exposure to bitcoin indirectly through investing up to 10% of its net asset value in Grayscale Bitcoin Trust ('GBTC'), a privately offered investment vehicle that invests in bitcoin," the filing with the U.S. Securities and Exchange Commission read.
Not really sure what indirectly means, though, leastwise, if you look at the companies today, there are a lot of them directly wanted to have bitcoin in their portfolio, so this could be where the money could come if the price will push to 6 digits in the future.
