On the user-facing side, Bithumb provides relatively competitive trading fees. The platform also implements a layered security model, with most funds stored in offline “cold wallets,” and security features such as two-factor authentication (2FA). For fiat operations, Bithumb primarily supports deposits and withdrawals in Korean Won (KRW), which may suit users with access to KRW banking.
However, Bithumb has a troubled security and regulatory history. The exchange suffered major hacks and security incidents in 2017 and 2018, including a breach that exposed user data and another that led to the theft of tens of millions of dollars in crypto assets. These events severely impacted user trust, though Bithumb claims it has improved security protocols, implemented cyber-insurance coverage, and adopted bank-style protections to prevent recurrence.
More recently, Bithumb has faced governance and compliance concerns. In 2025, prosecutors reportedly investigated the exchange over alleged misuse of corporate funds by a former executive — raising scrutiny over corporate practices, transparency, and regulatory compliance. Additionally, critics accuse Bithumb of opaque fee structures: while the exchange advertises very low commission rates, many users say achieving those rates requires applying discount “coupons,” making the real fee higher than advertised.
User feedback is mixed: some appreciate Bithumb’s liquidity and breadth of supported coins, while others report slow or poor-quality customer support, difficulties with withdrawals (especially for users outside Korea), and general distrust due to past incidents.
In summary, Bithumb remains one of the largest, most established crypto exchanges globally — with broad asset coverage, competitive fees, and improved security measures. At the same time, its history of hacks, governance controversies, limited fiat support, and mixed user satisfaction make it a risky option; users should proceed with caution and avoid storing large balances long-term.
