Why do some normal deposits and withdrawals also trigger risk controls or account restrictions?

Because in digital asset trading, deposits and withdrawals are not just "money goes out, coins come back."

Especially in C2C or larger-value OTC trades, banks and platforms may look at the source of the funds, which accounts they passed through, and whether the records are complete.

If the counterparty's fund source is complex, or the intermediate transfer chain is unclear — even if it is a normal trade — you may be asked to provide additional materials, or even face account restrictions.

Therefore, when understanding OTC, you cannot simply view it as "exchanging for U." OTC typically involves multiple steps between fiat and digital assets, including price inquiry, execution, payment/receipt, on-chain transfer, fiat settlement, and subsequent reconciliation.

In scenarios with large capital volumes, OTC usually appears in large stablecoin swaps, fund allocation, trading-related liquidity arrangements, corporate operational fund management, and cross-market capital flows.

Taking BIT OTC as an example, its public introduction includes the following features:

- Supports digital assets such as USDT, USDC, BTC, ETH, and also covers fiat settlement currencies like USD, HKD, EUR
- Supports self-service quoting, order placement, and viewing of history via Web/App
- Provides a dedicated service team for large or complex orders
- Offers same-name virtual accounts (VA), allowing customers to transfer funds between accounts in their own name or their institution's name and the same-name account

Overall, OTC is not just about completing an exchange — it also involves fund routing, settlement arrangements, and record keeping. When the amount is large or the path is complex, understanding these steps in advance is itself part of risk management.
