Summary

This page tracks public BitcoinII (BC2) exchange listings and current exchange-integration observations.

Exchange data is time-sensitive. A public trading pair does not prove that deposits, withdrawals, liquidity, or user-specific access are currently available.

For current confirmation-count evidence, see Exchange confirmation evidence — 2026-09-12.

Current direct exchange-source observations

CoinEx

Status: Active public BC2 listing / direct API status checked
Official: No, unless confirmed by BitcoinII maintainers
Public market: BC2/USDT
Deposits enabled: true in public deposit/withdraw configuration API on 2026-09-12
Withdrawals enabled: true in public deposit/withdraw configuration API on 2026-09-12
Trading enabled: Public BC2/USDT market exists; account trade execution was not tested
Confirmation policy: safe_confirmations = 2; irreversible_confirmations = 6
Last checked: 2026-09-12
Evidence level: Direct public exchange API / exchange page observation

Direct configuration query:

GET https://api.coinex.com/v2/assets/deposit-withdraw-config?ccy=BC2

Important interpretation:

CoinEx’s irreversible_confirmations is an exchange policy field. MoreBC2 does not describe six BC2 confirmations as cryptographically irreversible.

NonKYC

Status: Active public BC2 listing / direct API status checked
Official: No, unless confirmed by BitcoinII maintainers
Pairs: BC2/USDT and BC2/BTC publicly associated with the asset
Deposits enabled: depositActive = true on 2026-09-12
Withdrawals enabled: withdrawalActive = true on 2026-09-12
Trading enabled: Public BC2 market pages exist; account trade execution was not tested
Confirmation policy: confirmsRequired = 50; separate securityConfirmsRequired = 20 field has unresolved public semantics
Last checked: 2026-09-12
Evidence level: Direct public exchange API observation

Direct asset query:

GET https://api.nonkyc.io/api/v2/asset/getbyticker/BC2

Caution:

The same public record contained descriptive fields that do not match current BC2 technical facts, including isProofOfWork = false, and it contained Upcoming fork notes that may be stale. MoreBC2 therefore treats the operational status/confirmation fields as useful current exchange evidence without treating every descriptive field as protocol authority.

The meaning of securityConfirmsRequired = 20 has not been established from public documentation and must not be equated with CoinEx’s second-stage confirmation field.

NestEx

Status: Active public BC2 listing / direct backend status checked
Official: No, unless confirmed by BitcoinII maintainers
Public spot page: https://trade.nestex.one/spot/BC2
Deposits enabled: candeposit = true in public coin API on 2026-09-12
Withdrawals enabled: canwithdraw = true in public coin API on 2026-09-12
Trading enabled: spottrade = true in public coin API; account trade execution was not tested
Confirmation policy: explicit BC2 backend conf = 50
Decimals: 8
Last checked: 2026-09-12
Evidence level: Direct public exchange backend/API observation

Direct coin query:

GET https://api.nestex.one/v1/coins

NestEx’s Wallet Status frontend uses 50 as a fallback display when an asset has no explicit confirmation value. That fallback alone would not prove BC2’s configured count. The /v1/coins backend response resolves the ambiguity because the BC2 object itself explicitly returns conf = 50.

Other public evidence observed during the same review included a BC2 liquidity endpoint and proof-of-reserves pages showing BC2 wallet infrastructure. Those observations do not constitute a recommendation or a liquidity-quality guarantee.

Biconomy

Status: BC2 listing confirmed / current wallet policy only partially visible publicly
Official: No, unless confirmed by BitcoinII maintainers
BC2 listing metadata: Publicly retrievable
Deposits enabled: Current status not independently verified from a public wallet-status endpoint
Withdrawals enabled: Current status not independently verified
Trading enabled: BC2 listing/trading material remains public; current account trading was not tested
Confirmation policy: Not publicly verified
Last checked: 2026-09-12
Evidence level: Direct public Biconomy metadata and frontend/API review; wallet-specific configuration unresolved

Biconomy’s public BC2 metadata endpoint:

GET https://openapi.biconomy.com/api/v1/assetIntro/BC2

The record identifies BC2 / BitcoinII but does not expose deposit confirmation count or present wallet-status fields.

Biconomy’s public frontend contains a deposit warning parameterized with min_confirmation, showing that the platform uses a per-deposit confirmation value. Its public /api/v1/chains-config endpoint did not expose BC2-specific confirmation data during the 2026-09-12 check. Wallet-specific per-asset routes appear to require authenticated user context.

January 2026 wallet-upgrade incident

Biconomy announced the BC2 spot listing in January 2026 and initially announced deposits and withdrawals as available.

Shortly after launch, a community report stated that BC2 deposits were temporarily closed for a Wallet Upgrade. A later community follow-up reported deposits operational again and included a successful small test deposit.

MoreBC2 records this only as a dated wallet-service interruption. It does not infer the underlying technical cause, does not connect the event to later chain conditions without evidence, and does not treat it as proof of current deposit or withdrawal status.

Confirmation-policy comparison

Exchange	Current verified BC2 confirmation evidence
CoinEx	2 safe / 6 exchange-defined irreversible
NonKYC	50 deposit confirmations; separate securityConfirmsRequired = 20 meaning unresolved
NestEx	explicit BC2 backend conf = 50
Biconomy	not publicly verified

Two independently queried BC2 venues currently use 50 confirmations. This supports MoreBC2’s provisional 50-confirmation normal-deposit baseline, but it does not create a network rule or fixed finality guarantee.

See Deposit monitoring for the current operational guidance.

What has not been verified

For all venues above unless explicitly stated otherwise:

• No user account was logged into during the public checks recorded here.
• No order was placed.
• No deposit was sent.
• No withdrawal was performed.
• No exchange is being represented as safe, reliable, liquid, or recommended.
• Region/KYC/account-specific availability was not established.
• Public status can change after the dated check.

Third-party aggregators

Aggregators remain useful for discovering possible markets, but they should not be treated as proof that deposits, withdrawals, liquidity, or trading are currently operational.

Direct exchange sources should take precedence whenever available.

Update rules

For each exchange recheck:

• Record the date.
• Prefer direct exchange APIs and pages over aggregators.
• Separate listing existence from deposit, withdrawal, trading, liquidity, and account availability.
• Record confirmation settings exactly as the exchange exposes them.
• Preserve exchange-specific terminology without turning it into a protocol claim.
• Do not infer a disabled/enabled wallet state from a historical incident.

Verification

Status: Draft Primary sources checked: Direct public CoinEx, NonKYC, NestEx, and Biconomy APIs/pages plus current exchange documentation and dated community evidence where explicitly labeled Notes: CoinEx, NonKYC, and NestEx now have direct current BC2 confirmation/status observations. Biconomy’s listing is confirmed, but its current wallet availability and BC2 confirmation count remain publicly unresolved. No exchange is recommended or account-tested by this record.
