Pros and cons

Pros

  • Custody is self custody, so the keys stay with you and the backup method is a seed.
  • The operator is licensed by National Bank of Slovakia (NBS) under MiCA CASP 097900CAKA0000269926.
  • Proof of reserves is published, showing assets held against customer balances.
  • Deposits cover card and bank, and support runs on email, chat and phone.

Cons

  • The entry point is the first hurdle: buying starts at €10, where VaultLeap is priced at $0.
  • Self-custody means recovery rests on you, and the backup listed is a seed.
  • It is a mobile wallet, so keys sit on your phone rather than on separate hardware such as Trezor's hardware device.

Who it suits

  • People who want their own keys and a named regulator at the same time.
  • Holders who trade from a phone and fund with a card or a bank transfer.
  • Slovak and EU residents who want proof of reserves and a MiCA licence.

Who should look elsewhere

  • Not for a no-cost download: VaultLeap is priced at $0, while fumbi asks €10 to start.
  • Not for hardware storage: Trezor is a hardware device, and fumbi is a mobile wallet.
  • Not for handing keys to a platform: eToro runs custodial custody, and fumbi does not.

Frequently asked questions

What does fumbi ask before you can start buying?+

The entry cost to plan around is the opening purchase of €10, which is the stated minimum for buying. Coins are then bought inside the app, where the listed count is 110. For trading costs, the category taker fee median sits at 0.25%.

Is fumbi regulated and does it publish proof of reserves?+

Fumbi is authorised by National Bank of Slovakia (NBS), with the licence MiCA CASP 097900CAKA0000269926 issued to the legal entity FUMBI, s.r.o.. The company also publishes proof of reserves, showing assets against customer balances. Coins stay in self custody with you rather than with the operator.

How do I fund the account?+

Fiat deposits run through card and bank, so a card and a bank transfer both work. The money arrives in the same mobile wallet that holds your coins, and buying starts at €10. Deposits are handled inside the app rather than on a separate platform.

Which coins can I hold and trade?+

The listed coin count is 110, above the category median of 71.5, so the range covers major coins and a long tail. Holdings sit in self custody, so moving coins in or out does not hand them to the platform.

Can I reach support when something goes wrong?+

Support runs on email, chat and phone, which includes phone, chat, email and a help centre. That is a wide mix for a mobile app. Across the ranking, phone support appears in 20% of wallets, and a help centre in 87.8%.

What happens to my coins if I lose my phone?+

Custody is self custody, so the wallet holds your keys rather than an account balance. The backup method is a seed, which is yours to store. Losing the phone does not lose the coins as long as that seed is kept.

Where is fumbi based and how old is it?+

The operator is FUMBI, s.r.o., registered in Slovakia, and the company was founded in 2019. It runs as a cex exchange with a mobile wallet on top, so the same app handles buying and holding.

Does holding coins here protect me from losing money?+

Prices move in both directions and no wallet changes that. Across the market data, a typical share of retail accounts losing money is 70.15%. A licensed operator and self custody protect how your money is held, not what the market does.
