Ark Invest, the investment house led by Cathie Wood, bought another 162,325 shares in crypto exchange Coinbase (COIN) last Friday, according to an investor email seen by Decrypt.

The latest purchase, worth $9.26 million and split across the ARK Innovation ETF (ARKK) and the ARK Next Generation Internet ETF (ARKW)—139,105 and 23,220 shares, respectively—brings Ark’s total investment in COIN to approximately $19.73 million since the start of the year.

This follows a series of purchases made between January 5 and January 11, when Ark Invest bought a total of $10.47 million worth of Coinbase stock.
