21bitcoin vs KuCoin Comparison

21bitcoin has established itself as an Austrian Bitcoin app across German-speaking Europe and deals exclusively in Bitcoin. On instant purchases the provider charges a service fee of 1.49%, or 1.29% with a referral code; limit orders and instant sales cost 1.49%, and OTC orders from €100,000 cost 0.49% to 0.99%. In the savings plan no service fee applies from day 8 onwards, while the first seven days cost 0.99%. According to 21bitcoin, euro deposits, account management and Bitcoin custody are free of charge; a euro withdrawal costs €1.

Austria’s Financial Market Authority (FMA) granted FIOR Digital GmbH authorisation as a crypto-asset service provider under Article 63 of the EU’s MiCAR regulation by decision of 27 November 2025, so a clearly identifiable European supervisor stands behind the app. Customer Bitcoin is kept separate from the company’s own holdings; the cold-wallet keys are held by BitGo Europe GmbH, which itself holds a MiCAR authorisation from BaFin.

The savings-plan approach is refreshingly uncomplicated: purchases run hourly, daily, weekly, every two weeks or monthly from the euro balance, and the flat wallet-transfer fee of 0.00001 BTC is widely seen as fair. Users single out the automatic transfer to a personal wallet above defined thresholds as a genuinely useful security feature. 21bitcoin now also offers limit orders at a target price and variable interest of 1.21% p.a. on the euro balance; the interest is granted by Volksbank Raiffeisenbank Bayern Mitte eG, and 21bitcoin converts it into Bitcoin free of charge on request.

Because Bitcoin is the only asset on offer, 21bitcoin is not aimed at investors who want a broad crypto portfolio, a limitation some users do point out. Two-factor authentication in the app and the €10 minimum order are also seen as leaving room for improvement. That makes 21bitcoin a good fit for Bitcoin-focused investors in German-speaking Europe who save regularly and care about automatic wallet transfers and Austrian regulation.

In short: KuCoin is popular with altcoin traders: more than 800 coins worldwide, spot trading from 0.1%, plus futures, trading bots and earn products. For investors in the EU, KuCoin EU is responsible, the European company with a MiCA licence from Austria. Trading and deposits there have been paused since 4 February 2026. If you are looking for an account to trade today, choose an exchange that is fully operating.

Is KuCoin safe and licensed in the EU?

The licence is in place, trading at KuCoin EU is paused. KuCoin EU Exchange GmbH, based in Vienna, has been authorised as a crypto-asset service provider under Article 63 of MiCA since 27 November 2025, granted by Austria's Financial Market Authority (FMA). Through the EU passport the licence covers 29 EEA countries, including Germany, France and Spain (ESMA register, file of 30 October 2026). It covers custody, exchanging crypto-assets for funds and for other crypto-assets, placing and transfers.

Why trading is paused: On its website, KuCoin EU states that trading and deposits have been suspended since 4 February 2026 (as of 1 November 2026). The FMA ordered a ban on new business on 19 February 2026 because the money laundering and sanctions officer posts were no longer filled, and lifted it on 18 May 2026. Under a decision of 18 February 2026, however, KuCoin EU may only start operating once all supervisory requirements are met, in particular on governance and on filling further key positions in management (FMA notice). The FMA had not published any newer decision by 1 November 2026.

Track record: In January 2025, KuCoin's parent company Peken Global pleaded guilty in the US to operating an unlicensed money transmitting business, paid $297 million and withdrew from the US for at least two years (our report). In October 2026 South Korea blocked access to KuCoin because the exchange is not registered there (South Korea blocks 27 exchanges).

What you can do yourself: if you still hold funds at KuCoin, read the notices in your account, turn on two-factor authentication and a withdrawal address whitelist, and keep larger amounts in your own wallet, for example a hardware wallet.

Who is KuCoin for?

KuCoin suits experienced altcoin traders who want a very large choice of small coins and who live in a country where KuCoin accepts customers. For trading from the EU, exchanges with a MiCA licence and full operations are the better fit, such as Bybit EU, OKX, Kraken or Bitvavo.
