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.
These institutions have huge money and can really make an impact in the crypto community. If this move will continue, we will really see the price of bitcoin to continuously rise. Even if there is no clear legislations from the government towards crypto, we are now seeing big companies doing their move towards crypto. This will push thru the government to seriously consider the cryptocurrency market.
