CoinTrade: Japan spot quotes, staking and lending

CoinTrade’s dealing model is a Japanese sales-counter service: the customer accepts a platform quotation to buy or sell crypto. The official FAQ expressly distinguishes this from trading against other customers on an exchange order book. A displayed price therefore needs to be assessed as the actual conversion quote, including the difference between the platform’s buying and selling prices.[3]

The parent-company release dated 8 October 2026 says XDC increased CoinTrade’s supported assets to 26. It announces XDC recurring purchases and describes XDC staking as planned. That dated catalogue count does not establish that every asset supports every service, or that a subsequently planned staking product is already live. Check the asset inside the relevant product screen.[1]

Stopping a recurring purchase plan is an account action in its own right. The help instructions also require moving accumulated crypto from the recurring balance before selling or sending it. Stopping future purchases and releasing assets already accumulated are therefore separate steps; inspect both the plan status and the destination balance when ending an accumulation arrangement.[27]

CoinTrade explains its spread as the difference between the buy and sell quotation. It changes with prices and liquidity; the reviewed FAQ does not supply a fixed spread percentage. Compare the crypto delivered for the yen spent, and the yen obtained from a sale, at the actual order size. A favourable headline commission figure would not remove this quotation cost.[8]

Staking reward figures are indicative annualised rates derived from past operation. They are not a promise that the same rate will accrue throughout a future holding period. A displayed annual rate should be read alongside the lock and reward conditions for that asset; it is not an assured one-year cash return or an immediate withdrawal entitlement.[20]

Lending rates are set separately by asset and season and are shown in the relevant product information. The useful comparison is the rate and term accepted for the specific loan, together with when principal and interest become available. A rate observed for one season cannot be substituted for the next season’s offer or applied across the complete asset catalogue.[25]

Early lending termination is generally unavailable. If CoinTrade exceptionally accepts a customer-requested early exit, its FAQ says no interest is paid and a charge of 10% of the subscribed crypto amount applies, including consumption tax, rounded upward at the eighth decimal place. For an accepted early exit on 0.2 BTC, that percentage alone is 0.02 BTC. This is a conditional exit charge, not the cost of every ordinary maturity.[26]

The yen withdrawal workflow has additional balance controls: a residual balance at or below the withdrawal fee is not accepted except when making a full exit to zero. Existing withdrawal requests must all be approved before another request can proceed. Use the transaction history and completion email to distinguish a pending instruction from a completed remittance.[10]

For a crypto deposit, select the correct asset, generate or copy its receiving address and include any required destination tag or memo. The FAQ warns that a missing tag or memo can prevent crediting. The label of the coin alone is insufficient: the address, supported network and any ancillary identifier must all match the transfer being sent.[18]

BNB illustrates why the network check matters. CoinTrade’s specific BNB FAQ accepts BNB Smart Chain and warns that deposits over another network cannot be credited or recovered under its stated process. This is an asset-specific example; it does not establish the networks available for other coins or make a similarly named token interchangeable.[17]

An outgoing transfer to another exchange has an extra setup dependency: CoinTrade says the customer must first generate a CoinTrade receiving address for that asset. Without it, the outgoing request can be held and the customer contacted by email. Generate the address through the deposit screen, then follow the requested remediation; resubmitting identical transfer instructions does not resolve a missing required address.[19]

CoinTrade says customer money is held separately from its own money in trust with Nisshokin Trust & Banking, and customer crypto is distinguished from company assets in offline storage. These are the operator’s published asset-management arrangements. They explain how ordinary customer balances are described as being held, without proving that every possible insolvency outcome or recovery timetable is covered.[32]

The general storage FAQ states that 100% of customer crypto is held in offline cold wallets. This is an attributed company statement, not an independently inspected reserve audit. That short FAQ does not reconcile its description with the operational treatment of staked or lent assets, nor does it establish an insurance beneficiary, policy limit or guaranteed reimbursement. Obtain the relevant product terms before treating the general custody description as applicable to a yield position.[33]

If the old authenticator device remains available, the recovery instructions describe transferring authentication to the replacement device. If it is unavailable, the customer must request a reset and pass identity checks. CoinTrade also warns that registered passkeys are removed during that reset and must be registered again after two-factor authentication is restored. The reviewed procedure does not establish a precise post-reset withdrawal hold.[34]

The help centre provides app and PC instructions for the exchange and its associated products. Its published maintenance window is Wednesday 12:00–18:00; the notice says registration may still be possible while login and trading are unavailable. Emergency notices are distributed through the website, blog and official social account. Check the current notice before relying on access during that window.[35]

Support requests can be submitted at any time, but replies are handled during business hours. Requests outside those hours normally wait until the next business day, and holidays can add delay. An always-open form is therefore not a promise of continuous live dealing support. The reviewed response-hours FAQ does not publish a precise daily clock or guaranteed resolution deadline.[36]

The Financial Services Agency’s register dated 30 September 2026 lists 株式会社マーキュリー under Kanto Local Finance Bureau registration No. 00025, originally registered on 17 February 2021. The register row identifies the operator rather than a global group-wide permission. Read it as cryptoasset exchange registration in Japan; it does not itself certify an investment’s value or establish insurance for a customer’s balance.[2]

Mercury is a consolidated subsidiary of Ceres. The parent’s October release dates the CoinTrade trading launch to March 2021, the staking service to July 2022 and lending to July 2024. These milestones help distinguish the core trading account from products added later. No verified active-trader count or comparable exchange-volume statistic was established for this profile.[1]

Transaction history can be downloaded through the history area. Preserve the underlying trade, deposit and withdrawal records needed to reconcile money movements across banks, exchanges and personal wallets. An exported transaction history records platform activity; it should not be treated as a complete calculation of a customer’s tax liability across all venues and accounts.[38]

CoinTrade also issues a monthly transaction report at the beginning of the following month. That reporting cycle matters when reconciling a recent transaction: the newest activity may be visible in history before the relevant monthly report becomes available. Compare the reporting period with the dates you are trying to reconcile instead of assuming that the latest report includes the current month.[39]

Closure requires a support request and completion of any active staking, lending or recurring-purchase arrangements. Download records beforehand: the closure instructions say login and downloads cease afterward and records cannot then be retrieved through the service. Small residual balances can involve surrender to settlement charges; larger balances require the applicable consent or withdrawal process. Plan closure around product unlock dates and final transfers rather than treating it as a single instant button press.[40]
