Coincheck Review

A Coincheck review has to cover two very different chapters. The Tokyo exchange is today one of Japan’s most popular retail crypto apps, backed by a listed financial group and registered with the Financial Services Agency. Yet it is also remembered for one of the largest exchange thefts on record. Understanding both halves helps explain why Coincheck now looks the way it does.

The 2018 Hack and the Monex Turnaround

Coincheck’s operating company began life in 2012 as ResuPress and launched its crypto service in 2014, founded by Koichiro Wada and Yusuke Otsuka. In January 2018, attackers drained roughly 500 million NEM tokens, then worth about $530 million, from an internet-connected wallet. After initially warning it might not cover the loss, the company repaid around 260,000 affected customers in yen from its own capital.

Months later, in April 2018, Monex Group bought the business for 3.6 billion yen and rebuilt its controls. Coincheck went on to gain full registration as a crypto asset exchange service provider (No. 00014 with the Kanto Local Finance Bureau). In December 2024 its holding company, Coincheck Group N.V., listed on Nasdaq, which means quarterly financial disclosures are now public.

How the Business Looks in 2027

According to the group’s results for the year ended March 31, 2026, Coincheck had about 2.53 million verified accounts, up 10% year on year, and customer assets of roughly 728 billion yen. Revenue rose 25%, yet the group still posted a net loss of about 1.8 billion yen. It has been diversifying: it bought Next Finance Tech in 2025, French prime broker Aplo in October 2025, and Canadian asset manager 3iQ in February 2026, whose chief executive became group CEO in April 2026.

Two Ways to Trade, Two Cost Models

The pricing story hinges on which part of the platform you use.

Sales desk

The default buy and sell screen covers all of the roughly 35 listed assets and charges no visible commission. Instead, the price includes a spread, which reviewers point out can be noticeably wider than the order book. This is convenient for small purchases but expensive for frequent trading.

Exchange order book

The order book is where Coincheck stands out on cost. Bitcoin, Ether, XRP, Solana, Dogecoin, Avalanche and most other listed pairs carry 0% maker and 0% taker fees. A handful of tokens, including ETC, IOST, FNCT, BRIL and FPL, are charged 0.05% maker and 0.10% taker. CoinGecko tracks 22 pairs on this venue.

Funding can eat into those savings. Bank transfers are free apart from your own bank’s charges, but quick deposits and convenience-store payments start at 770 JPY. Every yen withdrawal costs 407 JPY. Crypto withdrawals use a sliding fee tied to network conditions, starting at 0.0005 BTC or 0.005 ETH.

Beyond Buying and Selling

Coincheck’s app has topped Japan’s crypto download charts for seven consecutive years, according to Sensor Tower data cited by the company. Around the core exchange it offers recurring purchases from 10,000 JPY per month, lending, staking (which passed 400,000 users in early 2026), an IEO platform, the Coincheck NFT marketplace and electricity and gas plans that pay rewards in bitcoin. In September 2026 it launched Coincheck Leverage, offering up to 2x on BTC, ETH and XRP against the yen, initially only on iOS.

Strengths and Weak Spots

• Strengths: regulated in Japan, transparent listed parent, free order-book trading on major coins, polished mobile experience.
• Weak spots: spread-based sales desk, costly instant deposits, limited coin list, no futures or copy trading, and a past hack that some users will not forget.

Bottom Line

Coincheck suits Japanese residents who want an easy app and are disciplined enough to use the zero-fee order book rather than the sales desk. It is not designed for international users, derivatives specialists or anyone hunting small-cap tokens. Its post-2018 reforms and public reporting have rebuilt much of its credibility, though the group is not yet consistently profitable.

Digital assets are volatile and unprotected by deposit insurance, so size positions with care.
