Nansen CEO Alex Svanevik has publicly criticized Coinbase Advanced's fee structure, labeling the 120 basis point taker fee as "outrageous." Svanevik expressed his dissatisfaction on the X platform, highlighting that his account's fee tier was adjusted to Intro 1, resulting in a new taker fee of 1.2% and a maker fee of 0.6%. These fees are reportedly determined by trading activity or asset holdings over the past 30 days.
