Mara Holdings, formerly known as Marathon Digital, has been making headlines recently for its significant investments in Bitcoin. In the last 8 hours alone, the company has added an estimated 1,627 BTC (worth approximately $166 million) to its wallets, according to blockchain data analytics firm Arkham Intelligence (ARKM). This latest purchase brings Mara Holdings' total Bitcoin holdings to an estimated 17,546 BTC, worth over $1.7 billion at current prices. The company has been steadily accumulating Bitcoin since 2020 and has become one of the largest institutional holders of the cryptocurrency. Mara Holdings' investment in Bitcoin comes amid growing interest from institutional investors in the cryptocurrency. In recent months, several major companies, including Tesla, MicroStrategy, and Square, have announced large purchases of Bitcoin. This increasing institutional adoption is seen as a sign of Bitcoin's maturing as an asset class.
