Digital Currency Group, the parent company of digital asset manager Grayscale Investments, is now authorized to purchase up to $750 million worth of shares of Grayscale Bitcoin Trust.

The company announced Monday that DCG increased its prior authorization to buy up to $250 million worth of GBTC shares by an extra $500 million.

The share purchase authorization does not obligate DCG to acquire any certain amount of shares in any period, and it may be expanded, modified or discontinued at any time, DCG noted. Actual purchases will depend on many factors like the levels of available cash as well as price and market conditions, the firm said.

DCG mentioned that the firm had purchased a total of $193.5 million worth of GBTC shares as of Friday. DCG plans to use cash to fund the purchases and will make the purchases at management’s discretion in compliance with Rule 10b-18 under the Securities Exchange Act, the company noted.

The news comes shortly after DCG originally announced in March its plan to purchase up to $250 million of GBTC shares. The move came amid volatile conditions for GBTC and plans to hire talent in the exchange-traded fund industry, which signaled a potential diversification by the firm.
