Separating long-term holdings with an OKX sub-account: a custody habit for Polish users
Keeping long-term coins and active trading funds in the same OKX account makes mistakes easier. How Polish users can use a sub-account to separate holdings, limit what tools can reach and keep transfers deliberate.

When savings and trading funds share one account, every action touches everything. A mistaken market order, an over-sized futures position or an API key connected to a trading tool can all reach coins you meant to hold for years. OKX allows users to create sub-accounts that sit under the main account with their own balances. Used carefully, a sub-account becomes a simple custody wall: long-term coins live on one side, active trading happens on the other, and moving money between them is a deliberate step rather than an accident. This guide explains how to set that up and keep it tidy.
Decide which side holds what
Before creating anything, write down your plan. A common arrangement keeps long-term holdings in the main account and uses a sub-account for trading, or the reverse if you prefer the main account for everyday use. What matters is that one side holds coins you do not intend to trade and the other holds a working balance. Read the OKX help centre pages on sub-accounts for how they are created and what each can do, since features and limits can change.
Keep tools and keys on the trading side only
If you use portfolio trackers, bots or tax tools, create their API keys on the trading sub-account rather than on the side holding savings. Give read-only or trade-only permissions and never enable withdrawals for third-party tools. This way, even if a key leaks, the long-term holdings are outside its reach. Label each key clearly and delete any you no longer use.
Make transfers between sides a conscious act
Moving funds between the main account and a sub-account is quick, which is useful but also a risk if done carelessly. Set a personal rule, for example transferring to the trading side only on a set day each month and only up to a planned amount. Record each transfer in a short log. If you find yourself moving savings to the trading side after a losing day, treat that as a warning sign and pause.
Protect the main account itself
A sub-account does not replace basic protection. The main account still needs a strong unique password, app-based verification or a passkey, an anti-phishing code and a withdrawal allowlist. If the main account is compromised, its sub-accounts are exposed too. Review active devices and keys on both sides every few months, and keep recovery information on paper somewhere safe at home.

Scenario checkpoint
- Write down which side holds long-term coins and which holds the working trading balance.
- Create API keys for trackers and bots only on the trading sub-account without withdrawal rights.
- Move funds between sides on a fixed schedule and log every transfer with its amount.
- Keep strong verification and an allowlist on the main account that controls the sub-accounts.
