Cathie Wood stated last week that the expense ratio of the Ark 21Shares Bitcoin ETF is only 0.21%, which will not result in any profits. Ark considers Bitcoin as a “public good”. Although the S-1 document does not disclose the expense ratio of the Ethereum ETF, according to Bloomberg analyst Eric Balchunas’ tweet, it is possible that the low fees led to Ark’s exit. In addition, 21Shares is gradually developing its own brand in the United States (registered in Switzerland).
