If you've already got a Coinbase or Kraken account for Bitcoin and Ethereum and you're now hunting for the smaller-cap coins they don't list, KuCoin is probably the exchange that keeps coming up. It carries over 1,000 tradable assets, which is more altcoin depth than almost any exchange most US and UK readers have heard of. Here's what actually using it looks like in 2026, fees included.
What KuCoin is (and isn't)
KuCoin is a Seychelles-based centralized exchange founded in 2017, built around spot trading, futures, and margin — with altcoin selection as its main draw over giants like Coinbase or Binance. It is not a beginner-friendly, plain-vanilla “buy Bitcoin” app; the interface leans toward traders who already know what a limit order and a funding rate are.
One thing that's changed and matters if you're comparing exchanges in 2026: KuCoin now requires mandatory identity verification (KYC) to deposit, trade, or withdraw. That's a reversal from its older “no-KYC-required” reputation. Unverified accounts can only close existing positions or redeem assets already on the platform — you can't open new trades without verifying, and even then, withdrawals without ID verification cap out around 30,000 USDT.
Fees
KuCoin charges a flat 0.10% maker/taker fee on both spot and futures — competitive, roughly in line with Binance and cheaper than Coinbase's standard retail fees. If you hold KuCoin's native token, KCS, you can turn on “KCS Pay Fees” in account settings for an automatic 20% discount on every trade, which is the single easiest fee-reduction move on the platform (no fee-tier volume requirements to hit).
The one fee to watch: KuCoin introduced a dormancy fee in 2025 for inactive, non-KYC'd accounts, charged monthly based on balance. If you're parking coins on KuCoin and not trading, either complete verification or don't leave a meaningful balance sitting idle.
Trading features
- Spot trading: standard order book, over 1,000 pairs.
- Margin trading: up to 10x leverage, with a choice between Cross Margin (whole account as collateral) and Isolated Margin (risk capped to one pair).
- Futures: up to 125x leverage available — high enough that it's a liability in untrained hands, not a feature to reach for casually.
- KuCoin Trading Bot: a free, built-in automation tool for grid trading and DCA strategies, no separate subscription needed.
Getting started: what the KYC flow actually involves
Signing up takes an email or phone number, but you won't get past “view-only” mode until you complete verification: a government ID upload, a liveness selfie check, and — for higher withdrawal limits — proof of address. Basic verification is usually processed within minutes to a few hours; it's the same friction level as Coinbase or Kraken at this point, so the “instant, no-ID exchange” reputation KuCoin had years ago no longer applies. Budget 10–15 minutes to get fully verified rather than expecting to be trading within seconds of signing up.

Is KuCoin safe?
KuCoin has not had a Mt. Gox or FTX-scale collapse, but it operates without a full license in several major jurisdictions, including explicit restrictions for US retail users on much of its derivatives product. It has also settled with US regulators in the past over unregistered securities/exchange activity. That's not disqualifying — plenty of large exchanges have regulatory scar tissue — but it's a materially different risk profile than a US-licensed, publicly traded exchange. If regulatory clarity matters more to you than coin selection, that's a real point in Coinbase's or Kraken's favor.
Honest pros
- Genuinely the widest altcoin selection of any major exchange most readers will encounter.
- Low, flat 0.10% trading fee, with an easy path to a further 20% discount via KCS.
- Free built-in trading bot — a paid add-on ($15–30+/month) on several competitors.
- Deep margin and futures tooling for traders who actually want it.
Honest cons
- Mandatory KYC now, so the “no-ID” era that built KuCoin's early reputation is over.
- Dormancy fees can quietly erode an idle unverified balance.
- 125x leverage is available, which is a real risk to anyone without strict position sizing discipline — this is not a “set it and forget it” platform.
- Regulatory standing is weaker than Coinbase's or Kraken's in the US and several other major markets; check your local restrictions before funding an account.
Editor’s pick: Coinbase or Kraken
KuCoin is not currently a live affiliate partner on this site. If you want a simpler, US-regulated on-ramp instead of KuCoin’s KYC-gated altcoin platform, see our Coinbase Review 2026 or Kraken Review 2026.
Who should actually use KuCoin
If you're a beginner who wants to buy Bitcoin and hold it, KuCoin is more exchange than you need — Coinbase or Kraken's simpler buy flow and stronger US regulatory standing are the better fit. If you already hold BTC/ETH elsewhere and specifically need altcoin pairs, low fees, and a free trading bot, and you're comfortable completing KYC, KuCoin earns its place as a second exchange rather than your only one.
FAQ
Is KuCoin legal in the US?
KuCoin operates for US users but with restrictions — much of its high-leverage futures and margin trading is not available to US retail accounts, and the exchange has faced past US regulatory settlements. Check current terms for your state before depositing.
Does KuCoin still allow trading without KYC?
No. As of 2026, KuCoin requires identity verification to deposit, trade, or withdraw new funds. Unverified older accounts can only close out existing positions.
What's the cheapest way to trade on KuCoin?
Enable “KCS Pay Fees” in account settings — it applies a 20% discount to the standard 0.10% maker/taker fee automatically, no volume tier required.
Is KuCoin better than Binance for altcoins?
Both list 1,000+ assets and charge similar 0.10% base fees. The practical difference for most US-based readers is regulatory availability — Binance.US operates as a separate, more limited entity, while KuCoin's main platform serves a broader (though still KYC-gated) global user base. Compare current coin listings for the specific tokens you want before choosing.
