KuCoin lists more altcoins than almost any rival exchange, but a $112.9 million DOJ fine, a two-year US exit and a fresh 2026 CFTC bar sit behind that catalog. We opened an account, checked the fee schedule and read through what the settlements actually require.
KuCoin lists coins that never make it onto Coinbase or Kraken, and that catalog is the actual reason anyone opens an account here. We tested the trading screen, checked the fee schedule, and then read through two separate US federal settlements to see what they actually change for a trader outside the US.
The catalog is the product
Search KuCoin for a token launched last month and there is a reasonable chance it is already listed. The exchange carries more than 1,000 assets across over 1,300 trading pairs, a depth few competitors match. That breadth cuts both ways: liquidity on a top-50 coin is fine, but a thin altcoin pair can show a spread wide enough to eat any fee advantage the moment you place a market order. We watched a handful of small-cap pairs during a quiet trading hour and saw exactly that gap.
Fees are competitive if you read the fine print
The base spot rate sits at 0.10% for makers and takers, undercutting several larger exchanges outright. Paying fees in KCS, KuCoin's own token, knocks a further 20% off that rate, and the VIP ladder drops the base further as 30-day volume rises, down to roughly 0.08%/0.10% once volume passes $5 million. None of these numbers are hidden, but they only show up once you dig past the homepage into the VIP privilege page, where the marketing leans harder on "up to 75% off" than on the plain starting number.
