Cathie Wood’s ARK Investment Management and Switzerland- grounded investment- products issuer 21Shares are having another pass at getting their spot bitcoin( BTC) exchange- traded fund( ETF) approved by theU.S. Securities and Exchange Commission. 

 The SEC rejected an operation for the ARK 21Shares Bitcoin ETF in April, citing a lack of investor protections. 

 A new form was made May 13 by Cboe BZX Exchange. 

 The SEC said in a form that it's soliciting commentary with respect to the new operation. 

The SEC has yet to authorize any spot bitcoin ETFs. It has either rejected or delayed those requests, while allowing finances that trade bitcoin futures. 

 In its form, Cboe said it believed it “ represents a regulated request of significant size ” and that the offer should be approved, according to the May 25 form.
