Good question.
According to my friend, no. Bitcoin spot ETFs will always be trading at some price or another, as Coinbase is always willing to sell at some price or another, as both the ETF providers and Coinbase make a percentage on each trade.
What adjusts is the BTC price. No pausing or circuit breakers. nostr:note1qd5t23t7ndcluy6qhetke8gpyc2rxfvgnpwkx9583cnjxztdda0qhyme5e
