bitFlyer review: Japan’s long-running licensed exchange, with FSA, EU MiCA and 49-state US coverage, but costly simple trades, a modest coin list, a past FSA order and NYDFS fine, and poor support ratings.
Thirty-second in our Crypto Centralized Exchanges series. bitFlyer, founded in 2014 and registered with Japan’s FSA since September 2017, is licensed in Japan, in the EU (a MiCA licence from Luxembourg on June 26, 2026) and in 49 US states plus DC. It reports segregated customer assets in cold wallets, 39 tradable assets in Japan, a Lightning order book with fees from 0.10% to 0.03%, and lending and staking. The record includes a June 2018 FSA business improvement order over identity checks and anti-money-laundering controls, and a $1.2 million NYDFS fine in May 2023 for cybersecurity failures. We found no named proof-of-reserves attestation, the simple Buy/Sell spread is not itemised on the fee pages we loaded, and Trustpilot shows 1.7 to 1.9 out of 5 on small samples. We weighted all of it.
Our take, up front: bitFlyer, founded in 2014 and registered with Japan’s FSA since 2017, is one of the few exchanges licensed across three major regions: Japan, the EU (a MiCA licence on June 26, 2026) and 49 US states plus DC. It reports segregated customer assets held in cold wallets, a Lightning order book with fees from 0.10% down to 0.03%, and lending and staking in Japan. The weaknesses are real: a 2018 FSA improvement order, a $1.2 million NYDFS cybersecurity fine in 2023, no named proof-of-reserves attestation, simple Buy/Sell trades that do not itemise the spread, a coin list well under the offshore giants, and Trustpilot ratings of 1.7 to 1.9 on small samples. We score it 64, tenth of thirty-two: just behind WhiteBIT and ahead of Bitpanda.
bitFlyer reports that customer crypto assets are held separately from its own and, on its homepage, that 100% of customer crypto is in cold wallets isolated from the internet; its security page says nearly 100%, so we treat the figure as company-reported and slightly inconsistent. We found no confirmed exchange hack in the sources we reviewed, though absence of reports is not proof of strong controls. The record is not spotless: on June 22, 2018 Japan’s FSA issued a business improvement order over weak identity verification and anti-money-laundering controls, and bitFlyer paused new account openings for about a year (CoinDesk). On May 1, 2023 New York’s DFS fined bitFlyer USA $1.2 million for cybersecurity programme failures found in 2018 and 2020 examinations, including no periodic risk assessment and template policies (Alston & Bird, BakerHostetler). Customer assets in Japan passed 1 trillion yen in November 2024 (company-reported). On October 15, 2026 bitFlyer is adding a Cooldown that limits outgoing crypto transfers after yen deposits for new Japanese accounts. We found no named proof-of-reserves attestation; one aggregator claims one exists but is excluded as unreliable.
Pros
- Customer assets segregated; cold-wallet custody reported at 100% or nearly 100% (company-stated)
- No confirmed exchange hack found; new Cooldown limits post-deposit transfers
Cons
- 2018 FSA improvement order and 2023 NYDFS $1.2M cybersecurity fine
- No named proof-of-reserves attestation found
Regulation is bitFlyer’s strongest point. In Japan it was registered with the FSA on September 29, 2017 (Kanto Local Finance Bureau No. 00003) and is a member of the JVCEA. In the US it received a New York BitLicense on November 27, 2017 and, after West Virginia on July 6, 2026, serves 49 states and the District of Columbia, with Hawaii the only gap (Finance Magnates, PR Newswire). In Europe, bitFlyer Europe received a MiCA crypto-asset service provider licence from Luxembourg’s CSSF on June 26, 2026, the first Japan-originated exchange to do so, which allows it to serve all 27 EU states. The marks against it are the 2018 FSA business improvement order and the 2023 NYDFS consent order.
Pros
- FSA registration No. 00003, NY BitLicense and an EU MiCA licence
- 49 US states and DC served
Cons
- 2018 FSA business improvement order
- 2023 NYDFS $1.2M consent order
On bitFlyer’s US fee page the Lightning order book charges 0.10% for 30-day volume under $50,000, falling to 0.03% above $500 million. Account creation is free and the page lists no crypto deposit fee. Withdrawals are fixed per asset, for example 0.0004 BTC and 0.005 ETH, and USD wire withdrawals cost $20. In Japan, Quick deposits cost 330 yen except through SBI Sumishin Net Bank, and the fee page lists Buy/Sell market trading as free, but customers bear the spread. That is the catch: the fee pages we loaded do not itemise Buy/Sell spreads, and CoinCodeCap says they can reach 6%, which we could not confirm. CoinCodeCap also lists EU card purchases at 1.95% plus 0.25 euros, unconfirmed on the official page. Older third-party pages cite 0.15% or 0.20%; we use bitFlyer’s schedule.
Pros
- Lightning spot fee from 0.10% down to 0.03% by volume
- Free account, no listed crypto deposit fee
Cons
- Buy/Sell spread not itemised and reported as high by one aggregator
- Fixed per-asset withdrawal fees; third-party fee figures conflict
bitFlyer’s own business page says 39 crypto assets are available for trading, and it added Solana on June 24, 2026. The mix varies by region and the US and EU lists differ, so check your own site. Products go beyond spot: the Lightning order book, Crypto CFD, margin trading in Japan at up to 2x (CoinCodeCap), lending and staking. Aggregators put the total at around 30 coins, which is lower than the company-stated 39, so we flag the conflict. The list is far smaller than large offshore exchanges, with no long tail of small caps and no perpetual futures on the scale of offshore rivals.
Pros
- 39 assets in Japan (company-stated); SOL listed June 2026
- Order book, CFD, margin (Japan), lending and staking
Cons
- Small list compared with large offshore exchanges
- Coin counts and products differ by region and by source
bitFlyer offers two interfaces: a simple Buy/Sell screen for newcomers and Lightning, an order-book platform with charts and API access. Reviews describe a clean, beginner-friendly app, but the simple screen costs more than the order book (CoinCodeCap). Hedge With Crypto notes that the app is available on web and mobile with recurring buys. G2 has only two reviews, one of which warns that open positions on Lightning may fail to execute and calls it suitable for basic BTC/JPY or ETH/JPY trading; the sample is far too small to generalise. bitFlyer reports top Bitcoin volume in Japan for ten consecutive years (company-compiled) and a No. 1 ranking for margin trading, lending and staking in the 2026 Oricon customer survey (company-announced).
Pros
- Simple Buy/Sell plus Lightning order book and API
- Company-reported No. 1 Bitcoin volume in Japan and Oricon rankings
Cons
- Simple screen is the expensive option
- Independent reviews are few and mixed
Independent support ratings are poor, though the samples are small. Traders Union, citing Trustpilot, shows 1.9 out of 5 on 28 reviews for bitFlyer USA as of July 2026, 89% of them one star; Gridinsoft recorded 1.8 on 31 reviews for bitflyer.com in October 2025 and RFP.wiki shows 1.7 on 29. G2 lists 2.0 on two reviews. Complaints in these summaries centre on slow, form-based support, account freezes and withdrawal friction (RFP.wiki). An older Hedge With Crypto review lists the lack of live support as a drawback. On the positive side, a regulated entity must run formal complaint processes, and one older G2 review praised support and liquidity.
Pros
- Regulated entities must run formal dispute processes
- Help centre and contact forms available
Cons
- Trustpilot 1.7 to 1.9 out of 5 on small samples
- Support is form-based; complaints cite account freezes and slow replies
The ecosystem is built around earning and spending. bitFlyer offers lending (launched December 2024) and staking, including Ethereum staking in Japan at about 1.74% after a 30% service fee per CoinCodeCap, a bitFlyer Credit Card, and a Crypto CFD product. It has run IEO-style token listings (ELF, with timely disclosures from Aptos Japan) and sponsored the WebX2026 conference in Tokyo. Staking is not available in the US. The extras are useful but modest next to the biggest platforms.
Pros
- Lending, staking, credit card and CFD in Japan
- Regular token disclosures and industry sponsorship
Cons
- Staking not offered in the US
- Smaller ecosystem than the largest exchanges
A licensed exchange across Japan, the EU and the US with segregated cold-wallet custody, but weigh the past FSA order and NYDFS fine, the unitemised Buy/Sell spread, the modest coin list and the poor support ratings.
bitFlyer suits residents of Japan, and regulation-first investors in the US or EU, who want a licensed on-ramp. Use the Lightning order book rather than Buy/Sell for anything regular, compare the quoted price before confirming a simple trade, expect Cooldown limits on new Japanese accounts, test a small withdrawal first, and keep long-term holdings in self-custody.
Tenth of thirty-two: licences in Japan, the EU and the US with segregated cold storage, but a past FSA order and NYDFS fine, an opaque Buy/Sell spread and poor support ratings.
bitFlyer scores 64, just behind WhiteBIT (64.25) and ahead of Bitpanda (63.75), Binance (61.25), Bitso (60), Bitget (59.5), BingX (59.25), Robinhood Crypto (59), Bitfinex (58.75), KuCoin (58.5), Luno (58.25), MEXC (58), Bitstamp (57.75), Gemini (57.25), Bithumb (55.5), CoinDCX (55), Toobit (54), Binance.US (53.75), Phemex (52.5), Bitkub (51.5), Bitrue (51.25), BloFin (51), LBank (50.5) and HTX (45.5); it trails Kraken (74), Bitvavo (70), Coinbase (69.25), OKX (69), Crypto.com (67.75), Bybit and Gate (66), Upbit (64.5) and WhiteBIT. It earns its marks on licences in three major regions, segregated cold-wallet custody, low Lightning fees and lending and staking. It loses ground on a 2018 FSA improvement order, a 2023 NYDFS fine, no named proof-of-reserves attestation, an opaque Buy/Sell spread, a modest coin list and Trustpilot ratings of 1.7 to 1.9 on small samples. Revisit the score if bitFlyer publishes an independent reserves attestation, itemises Buy/Sell spreads or support ratings improve.
The scorecard above is deliberately general. Whether bitFlyer is right for you depends on where you live, which interface you trade on and how much risk you accept from an exchange with no verifiable proof of reserves and weak support ratings.
The Japan resident who wants a licensed yen on-ramp
FSA registration No. 00003, yen deposits and withdrawals, segregated customer assets and a Lightning order book suit residents who want a regulated domestic exchange.
The regulation-first US or EU investor
A New York BitLicense, 49 US states and a MiCA licence from Luxembourg suit investors who prioritise licences, as long as they accept a smaller coin list.
The Lightning spot trader
Fees from 0.10% to 0.03% by volume are competitive, but trade on the order book, because the simple Buy/Sell screen costs more.
Altcoin hunters and anyone who needs fast support
The list is far smaller than large offshore exchanges, and independent support ratings of 1.7 to 1.9 out of 5 are a caution.
These four tables cover the specifics we didn't want to bury in prose: the fee picture, the reserves and incident timeline, regulatory footprint, and how the exchanges in this series compare.
What bitFlyer charges (and where sources conflict)
| Item | Maker | Taker | Source note |
|---|---|---|---|
| Lightning spot, under $50,000 (30 days) | 0.10% | 0.10% | bitFlyer US fee page |

| Japan site, Buy/Sell and exchange tiers | Free to 0.02% | Free to 0.02% | Japan fee page lists market trading as free (spread applies) and 0.02% or 0.01% at high volume |
| EU card purchases | 1.95% + EUR 0.25 | 1.95% + EUR 0.25 | CoinCodeCap; not confirmed on the official page |
| Crypto withdrawals | Fixed | Fixed | For example 0.0004 BTC and 0.005 ETH (US fee page) |
| Crypto deposits | Not listed | Not listed | US fee page lists no deposit fee |
| Yen and USD transfers | See note | See note | Japan quick deposit 330 yen (free via SBI Sumishin Net Bank); US wire withdrawal $20 |
| Older third-party figures | 0.15% to 0.20% | 0.15% to 0.20% | Older pages (FXEmpire, CoinMarketCap); we use bitFlyer’s own schedule |
Fees differ by region and change over time. We could read the US schedule in full but only part of the Japan page, and an aggregator listing 0.16% and 0.26% was excluded as unreliable. Check current figures before trading.

bitFlyer says customer assets are segregated and held in cold wallets: 100% on its homepage, nearly 100% on its security page. We found no named proof-of-reserves auditor or attestation. One aggregator claims proof of reserves exists; we excluded that page and could not verify the claim.

Category scores are out of 10 and weighted as shown, taken from each review in this series.
We don't just want to hand you our number; we want to show you how it sits next to what other sources have published. Round-ups like the licences, low Lightning fees and lending and staking, but consumer ratings are harsh, and our score lands above the blended figure.
Our score lands above the aggregated figure, because poor consumer ratings pull the blend down, while our scorecard weights regulation and custody more heavily and credits the three-region licences.

Scores compiled by our editorial team from publicly available reviews as of November 2026.

bitFlyer says customer assets are segregated from its own and held in cold wallets (100% on its homepage, nearly 100% on its security page). We found no confirmed exchange hack, but absence of reports is not proof of strong controls. Against that, Japan’s FSA issued a business improvement order in 2018, New York’s DFS fined bitFlyer USA $1.2 million for cybersecurity failures in 2023, and we found no named proof-of-reserves attestation. Keep long-term holdings in self-custody.
Yes, in three regions. In Japan it is registered with the FSA (Kanto Local Finance Bureau No. 00003) and belongs to the JVCEA. bitFlyer Europe received a MiCA licence from Luxembourg’s CSSF on June 26, 2026. bitFlyer USA holds a New York BitLicense and serves 49 states and DC, with Hawaii the only gap. Verify the entity serving your country on the regulator’s register.
On the US fee page the Lightning order book charges 0.10% for 30-day volume under $50,000, falling to 0.03% above $500 million. Account creation is free. Withdrawal fees are fixed per asset, such as 0.0004 BTC. The simple Buy/Sell screen is priced through the spread, which the pages we loaded do not itemise, so compare the quote before you confirm. Fees differ by region.
Buy/Sell is the simple screen for one-off purchases, with the cost built into the price. Lightning is the order-book platform with maker and taker fees, charts, margin in Japan and API access. For regular trading, reviewers recommend Lightning because Buy/Sell costs more.
bitFlyer says 39 crypto assets are available for trading and added Solana on June 24, 2026. Aggregators cite about 30, and the list differs by region, so check the site that serves you. It does not have the long tail of small caps that large offshore exchanges list.
From October 15, 2026, individual Japanese customers within 90 days of identity verification face a 48-hour limit on sending crypto externally after each yen deposit: the amount sendable is capped at the yen deposited in the past 48 hours minus 100,000 yen. Buying, selling, holding and receiving are not restricted. It is a fraud-prevention measure.
Independent ratings are poor on small samples: Trustpilot shows 1.9 out of 5 on 28 reviews for bitFlyer USA (Traders Union, July 2026), and other trackers show 1.7 to 1.8. Complaints centre on slow, form-based support and account or withdrawal friction. Treat this as a caution rather than a verdict.
bitFlyer scores 64 against Bitpanda’s 63.75, close to a tie. bitFlyer’s edge is licensing breadth across Japan, the EU and the US; its drags are poor support ratings and a modest coin list. See our Bitpanda review for how that exchange differs.
