SoFi Steps Back From Crypto. Cathie Wood's big purchase of SOFI stock

$ARK Innovation ETF(ARKK.US)$ Cathie Wood favors innovative companies with a technology angle. Wood reportedly once predicted that $Bitcoin(BTC.CC)$ would reach $1.48 million by 2023.
Interestingly, Wood (or more accurately, Ark Invest) bought $1.5 million worth of SOFI stock. That’s a big chunk, and this purchase clearly signals Wood’s confidence in SoFi Technologies. Still, it’s difficult to determine exactly why Wood invested so much money in SoFi.
In contrast, Ark Invest reportedly sold shares of $Coinbase(COIN.US)$ stock. Is Wood trying to make a statement here? Is Ark Invest deliberately shifting away from cryptocurrency and blockchain-related investments?
