After dropping 6.4% in its first session as a publicly traded company, Bakkt Holdings (NYSE:BKKT), the cryptocurrency exchange that's partly owned by Intercontinental Exchange (ICE +0.6%), gains as much as 4.6% in choppy trading on Tuesday. Bakkt's (BKKT) profile was also boosted by Coinbase noting its role in powering cryptocurrency spending and rewards features for Bakkt (BKKT), among others. For some background, ICE (NYSE:ICE) holds 30% of Bakkt's public common stock after it completed its combination with Victory Park's SPAC, VPC Acquisition. ICE's stake, though, is higher than that because it's also a PIPE investor in Bakkt. The 30% share doesn't include underlying private placement warrants, which become exercisable within 60 days of Bakkt's prospectus filed on Sept. 17. Bakkt (BKKT) stock price rises 1.1% in late morning trading as seen in chart below. Previously (Oct. 18), Bakkt, crypto exchange launched by ICE, drops as much as 6% in trading debut
