&#34;Wood Sister&#34; Cathie Wood used to hold a large amount of NVIDIA stock. However, in the past year, her Ark Invest fund has sold most of its AI stocks after profiting from the AI stock market frenzy and instead invested in other growth stocks. Currently, Ark only holds NVIDIA stock worth $81 million.At the same time, Ark has been actively buying Tesla (TSLA.US) stock, making four large purchases just last week and continuing to increase its position on Monday. However, Tesla is not Wood's largest holding. According to Zhitong App, Wood's largest holding is the cryptocurrency trading platform Coinbase Global (COIN.US), with an investment of $911 million, accounting for 6.8% of Ark's total assets, far higher than Tesla's 5.7% and NVIDIA's 0.6%.Despite the recent surge in Coinbase's price, Ark has reduced its holdings, but it remains Ark's largest position. This reflects Wood's confidence in the long-term development of the cryptocurrency industry. She is optimistic about the continued growth potential of cryptocurrencies and sees Coinbase and the newly launched Ark 21Shares Bitcoin ETF (ARKB.US) as industry pioneers.Wood highly values Coinbase. She is optimistic about the cryptocurrency market, especially Bitcoin, and has set a price target of $1.48 million for 2030. She believes that due to Bitcoin's design, which is almost immune to inflation and has a strictly limited supply, its price is expected to rise significantly as the global economy undergoes digital transformation.Therefore, she sees Coinbase as a leading investment in Bitcoin and other cryptocurrency asset management infrastructure. Coinbase stands out among cryptocurrency service providers due to its US background and emphasis on regulatory compliance. In contrast, competitors like Binance have been controversial due to alleged criminal activities and data security issues.Wood believes that Coinbase's business strategy makes it a safer choice and a more reliable option for investors looking to capitalize on the growth of the cryptocurrency market. Her fund has been buying Coinbase stock when scandals or fraud in other parts of the cryptocurrency market have caused stock prices to fall.Since June 2023, Wood's fund has reduced its holdings of Coinbase stock by about half, reinvesting the cash profits into other growth stocks.In addition, some of the funds originally invested in Coinbase have been redirected to more direct Bitcoin investments. Ark currently manages its own Bitcoin ETF, and her other funds hold shares of the Ark 21Shares Bitcoin ETF.As of Tuesday's close, Coinbase fell 1.51% to $130.82.
