KuCoin has permanently banned all US users following a DOJ indictment in March 2024 on anti-money laundering charges, which resulted in a $297 million forfeiture agreement. Any KuCoin referral code used from California violates both the platform's Terms of Service and places the user in potential conflict with US federal law. Do not attempt to access KuCoin with a VPN. US users who have existing KuCoin accounts have been required to close them and withdraw funds. This situation is not expected to change.
The Best Crypto Bonus Actually Available in California
KuCoin is off the table for US users. CEX.IO is fully licensed for California residents and is offering a legitimate welcome bonus for new spot trading accounts — no legal risk, no VPN required.

Before KuCoin's DOJ indictment and subsequent ban on US users, the platform operated one of the broader referral programs available on any major exchange. The referral structure had two components. First, the referrer earned 20% of all trading fees generated by users they referred — a recurring commission that continued for the lifetime of the referred account. Second, new users who signed up with a referral code gained access to a welcome bonus package that included a 10 USDT trial fund (usable for spot trades without risking personal capital) and the ability to unlock up to $500 in additional bonuses by completing a series of onboarding tasks.
The task-based bonus structure followed a pattern common across major exchanges: KYC verification, a qualifying deposit above a minimum threshold, execution of a first spot trade, and reaching specific cumulative trading volume milestones each unlocked incrementally larger bonus amounts. KuCoin's 700+ tradable assets and low base trading fees of 0.1% made it a genuinely competitive platform for non-US users completing these tasks.
None of this is available to California or any other US residents. Following the DOJ indictment and $297 million settlement, KuCoin implemented a full ban on US accounts. This is a hard block, not a soft georestriction. Attempts to circumvent it carry meaningful legal and financial risk.
The DOJ Indictment and What It Means for US Users
In March 2024, the US Department of Justice indicted KuCoin and two of its founders on charges of operating an unlicensed money transmitting business and conspiracy to violate the Bank Secrecy Act. Federal prosecutors alleged that KuCoin had deliberately accepted US customers over a period of years while failing to implement adequate anti-money laundering controls, failing to register with FinCEN, and failing to implement meaningful Know Your Customer procedures that would have excluded US users as required by law.
The indictment alleged that KuCoin processed over $5 billion in suspicious transactions and acted as a conduit for criminal proceeds. As part of the resolution, KuCoin agreed to a $297 million forfeiture and the platform's founders faced personal criminal charges. KuCoin agreed as a condition of the settlement to permanently exit the US market.
For California users, this means KuCoin is not a grey-area platform like some exchanges with incomplete US licensing — it is an exchange that has been found by federal prosecutors to have violated US law, and which is now contractually prohibited from serving US customers as part of a court settlement. The legal exposure for US users attempting to use KuCoin through a VPN extends beyond simply violating ToS: it may involve engaging with a platform operating under a federal compliance monitor in violation of the settlement's exclusion terms.
How KuCoin's Referral Program Works for Eligible (Non-US) Users
Register from an eligible country using a referral code
Non-US users sign up at kucoin.com and enter a referral code at registration. The code must be entered at this stage — it cannot be applied after account creation. US users will be blocked at registration.
Complete KYC identity verification
KuCoin requires identity verification for bonus eligibility and withdrawals above basic thresholds. US-issued documents will trigger account rejection as part of KuCoin's post-settlement compliance obligations.
Receive the 10 USDT trial fund
Upon completing KYC, eligible new users receive a 10 USDT trial fund credited to their account. This can be used for spot trades but cannot be withdrawn directly — only profits derived from it may be withdrawn.
Make a qualifying deposit and complete task milestones
Depositing above the qualifying threshold and completing specified trade volume milestones unlocks incremental bonus amounts up to the $500 ceiling. Each task tier releases a portion of the available bonus.
Referrer earns 20% of referred user's trading fees
The referring account earns a 20% commission on the spot and futures trading fees of all users they referred, on an ongoing basis. This commission continues for the lifetime of the referred account.

Frequently Asked Questions
Can I use a KuCoin referral code from California in 2026?
No. KuCoin permanently exited the US market as a condition of its 2024 DOJ settlement. California residents are banned from creating or maintaining KuCoin accounts. Attempting to use a KuCoin referral code from California violates KuCoin's Terms of Service and the terms of KuCoin's federal settlement agreement. Any bonuses claimed would almost certainly be voided, and deposited funds may be at risk of freezing.
What exactly happened with KuCoin and the DOJ?
In March 2024, the DOJ indicted KuCoin and two of its founders for operating an unlicensed money transmitting business and Bank Secrecy Act violations. KuCoin agreed to a $297 million forfeiture agreement and, critically, agreed to permanently ban all US users as a condition of the settlement. This makes KuCoin's US exclusion legally binding, not merely a business policy choice.
Is using a VPN to access KuCoin from California risky?
Yes — more so than with other banned exchanges. Because KuCoin's US exit is a condition of a federal court settlement, US users accessing the platform through a VPN are potentially engaging with a platform that is contractually prohibited from serving them under a federal compliance framework. Beyond the near-certain ToS violation, there is meaningful legal ambiguity about the position of US users who attempt to circumvent these restrictions. We strongly advise against it.
