Bixin.com: exchange fees, off-platform trades and Hong Kong custody

The functional guide names BTC/USDC, ETH/USDC and ETH/BTC; its fiat expansion remains labelled coming soon.[5]

Later pricing and withdrawal tables include USD pairs and fiat releases.[6][10]

A tariff does not by itself establish an enabled order book. Check the intended pair before funding for a particular transaction.

Matching follows price, then time priority. Unfilled limit quantities can rest. Market orders consume available liquidity until filled or the 10% price-deviation control intervenes; the remainder is cancelled.[5]

The permitted price range does not guarantee a complete fill.

The off-platform mechanism uses provider APIs internally. This describes how Bixin obtains and executes a quote; it does not establish that an ordinary customer receives a public trading API or unrestricted access to the provider. Its operational sequence is quote, asset reservation, provider confirmation and settlement. An attempted order and a completed conversion are consequently different states that should be reconciled in the account history.[7]

The published exchange rates are 0.2% maker and 0.4% taker.[6]

Off-platform execution carries a listed 0.4% service charge.[8]

A limit order that immediately crosses available liquidity can be a taker order. Compare the actual execution classification, price and funding charges when assessing the trade.

Equal headline percentages do not establish equal total cost between the order book and off-platform route. The price supplied by a liquidity provider can differ from the exchange’s executable price for the same size. Compare the final amount received after the applicable fee and any requote. The liquidity-provider guidelines describe selection criteria including capital, technology and risk controls, but do not publish a guaranteed spread, fill rate or independently measured depth.[8][23]

Deposit instructions require selecting the token and network. The exchange guide then directs an internal funding-to-trading account transfer.[12][4]

These are separate steps: a completed blockchain deposit can create a funding balance without yet creating the balance available for an order. Retain both the external deposit and internal transfer records.

The tariff charges 0.0001 BTC for deposits below 0.05 BTC and lists other deposits as free.[10]

On a hypothetical 0.01 BTC deposit, 0.0001 ÷ 0.01 × 100 = 1%. That calculation excludes any network fee charged by the sending wallet.

The historical small-deposit notice connects the charge to managing numerous small Bitcoin inputs.[11]

Complete bank rails, cut-offs, account-name requirements and refund charges were not established in the inspected Hong Kong help material.[3]

Obtain the account’s current banking instructions before funding in fiat.

A trading-size allowance and a daily withdrawal cap answer different questions. For a large planned exit, compare the expected balance with the applicable release limit; approval to trade does not itself establish immediate external delivery.

The custody disclosure identifies NewBX Treasures Limited, TCSP TC009090, as the associated entity holding client assets on trust. It permits pooling with other clients’ assets. This is custodial accounting, rather than a statement that each customer controls a separate private key. Pooling makes accurate entitlement records important even where the associated assets are segregated from the business’s own interests.[13]

The voting policy has a practical timing consequence. A customer who wants to participate in a time-limited governance decision may need to arrange withdrawal before the relevant deadline, allowing for account processing and network confirmation. Merely holding a balance on the exchange does not mean the platform will vote it or pass an instruction to a protocol. Check the asset’s own governance rules as well as the venue’s release process.[14]

Bixin’s Hong Kong individual-verification guide contains separate retail and professional pathways. Retail verification includes personal particulars, identity, address, risk-profile and virtual-asset knowledge checks, followed by the stated certification process. Professional verification adds financial information, asset evidence and a declaration. These are documented application routes, not a finding that every resident or asset is eligible under current account conditions.[15]

The token-admission policy allocates review to business, listing, compliance, technology and a senior review committee. It also contemplates suspension or withdrawal when eligibility changes. That explains why an existing balance and an available buy button can diverge over time. When a token is restricted, the meaningful instructions are the permitted sale or withdrawal route and its deadline; a historical listing should not be treated as permanent trading access.[22]

The authenticator article explains binding Google Authenticator using a saved setup key and completing a six-digit code check. It stresses secure retention of that key. Despite the article’s recovery title, it does not establish a complete manual procedure for a customer who has lost both the device and the saved key, or a fixed post-reset withdrawal hold. Restoring codes from a retained key and passing a manual identity-recovery process are different situations.[17]

The business-continuity disclosure describes alternative workplaces, protection of records and alternative contact arrangements communicated through the website or platform if normal channels fail. It does not publish a universal emergency execution number or a guaranteed restoration time. A support contact during an outage should therefore be treated as an escalation request until the venue confirms the status of the actual trade or withdrawal instruction.[18]

The risk disclosure makes company recording and confirmation consequential to transaction execution.[19]

For complaints, the agreement identifies in-account customer service; no universal resolution deadline was established.[2]

After a connection failure, preserve the order identifier, timestamp and displayed status before retrying.

The SFC lists NewBX Limited, BUY737, operating Bixin.com, licensed on 18 May 2026.[1]

This profile assesses the licensed NewBX relationship. It does not extend the permission to unrelated wallet products or every service marketed under the wider brand.

The dynamically rendered register conditions were not retrievable. Retail onboarding documentation is described here as an application pathway, subject to service and asset approval.

NewBX’s own brand clarification warns about similarly named platforms and social accounts and directs enquiries to the official support address. This is relevant when searching for an app, responding to a support message or following a claimed migration notice. The reviewed primary sources do not establish a new merger or brand migration requiring customers to move assets elsewhere. They also do not provide a comparable current NewBX active-trader or exchange-volume total.[21]

The deletion guide tells customers to withdraw or spend remaining balances before deleting an account and to contact support if a balance is below the withdrawal minimum. It provides an in-app route and a request from the registered email. Deletion removes customer access, so trade and transfer records should be saved first. This is a voluntary closure process; it does not establish an automatic inactivity charge or a dormant-account deadline.[20]

The functional guide describes recording trades and order states. The spot guide identifies an open-order view.[5][4]

The inspected material did not establish a complete CSV export, tax calculation or post-closure reporting portal. For reconciliation, retain trade consideration, fee asset, internal transfer and external deposit or withdrawal references separately.

Provider APIs form part of the documented off-platform execution mechanism.[7]

The agreement restricts unauthorized third-party software and use of another person’s account.[2]

Those facts do not establish a public customer API permission model. No native copy-trading or autonomous AI service was established for NewBX. An integration needs defined account authority and a way to stop new instructions while reconciling existing orders.
