Digital asset manager Grayscale Investments reached $16.4 billion in assets under management (AUM), up from the $13 billion the firm announced last week.
Data tweeted by the firm showed its largest holdings remain in bitcoin, with the Grayscale Bitcoin Trust having $14.1 billion in the top crypto asset. The firm's Ethereum Trust now has $1.81 billion in AUM.
Grayscale also has trusts for litecoin ($125.0 million), bitcoin cash ($70.7 million), ethereum classic ($67.7 million) and others with less significant holdings including XRP, XLM and zcash.
New York-based Grayscale is owned by Digital Currency Group, the parent company of CoinDesk.
Many major institutions have turned out in a positive manner and favours their treasure reserve or AUM by replacing them with crypto holdings mainly bitcoin and Greyscale,one of the largest institutional investors in the crypto space is on fire.Greyscale trust now holds around 506,000 bitcoin which is around 2.73% of total bitcoin supply of 21 million.Since july their holdings have gone too high and it is good to see that are ready to invest even after the price have crossed $22-$23k mark which is ATH since 2009which in return indicates that prices will surge high with these kind of investments and bull run will continue its mark till $30000 as they are benefitting from this price rise.If they keep on investing at the same pace they would have roughly 3.4% of btc supply which in long run will increase their profit margin and share prices too high

Here is the list of major companies that have AUM in bitcoin:
1) MicroStrategy-41000 bitcoins
2)Tezos foundation-24518 bitcoins
3)Galaxy Digital-16,402 bitcoins
4)Stone bridge holdings-10000 btc
5)ETC group-7021 bitcoins
