Here is an audio of BlackRock from their CEO in which he supports his large purchases in btc saying:
“We believe that #Bitcoin is an asset class in itself”
That he sees it as an alternative to other commodities such as Gold.
And in my opinion once a regulation is established worldwide for cryptocurrencies is when btc will begin to be seen as a store of value within this market, but for that maybe a few years will pass until the adoption of cryptocurrencies is so large that governments begin to create a market and further promote this sector.
