How do I deposit and withdraw funds on Bithumb?

[etfs]

Bithumb supports deposits and withdrawals in both KRW (Korean Won) and cryptocurrencies. To deposit fiat, users link a verified bank account, while crypto deposits require sending coins to your Bithumb wallet address. Withdrawals work similarly: fiat is sent back to your linked bank, and crypto can be transferred to an external wallet. Note: Bithumb may charge small transaction or network fees.
