Pros and cons

Pros

  • Self-custody with a seed backup, so keys stay with the holder: self custody and seed.
  • Regulated by the National Bank of Slovakia under MiCA licence MiCA CASP 097900CAKA0000269926.
  • Staking portfolio pays 3% to 5% and the lock-up terms are None; withdraw at any time.
  • Fiat deposits by card and bank, with support across email, chat and phone.

Cons

  • Coin coverage is narrower than hardware wallets: from 100 against a 5,500 median in that group.
  • Custody sits in the minority here: 50.5% of wallets in the ranking share it.
  • Staking covers Ethereum, Solana and Polygon only, a short list next to the 110 coins in the catalogue.

Who should look elsewhere

  • Coin maximalists, who will find 110 coins against from 100 at the low end of the hardware wallet range
  • Readers who want cold storage, since fumbi runs a mobile wallet and a cex setup
  • Anyone who needs yield above 3% to 5%, as the portfolio tops out below the 7% median

Frequently asked questions

What does fumbi cost to start?+

The wallet entry point is €10. Beyond that, the staking portfolio pays 3% to 5% and the lock-up terms are None; withdraw at any time, so costs sit mostly on trading rather than on holding. The price median across wallets in this ranking is €0.

Who regulates fumbi?+

fumbi is listed with the National Bank of Slovakia under MiCA licence MiCA CASP 097900CAKA0000269926, and the company is FUMBI, s.r.o. in Slovakia. The register files it as a crypto-asset service provider under the EU framework.

Does fumbi hold my coins?+

The wallet is self custody, and the backup is a seed, so the key material stays with the holder. Custody is listed as a feature too. Many wallets in the ranking run custodial instead, at 49.5%.

Which coins can I stake?+

The staking portfolio covers Ethereum, Solana and Polygon. That is a short list against the wider catalogue of 110 coins, and from 100 is the floor for coins supported in general. The category median for coins supported sits at 49.

Can I withdraw my stake at any time?+

Yes, you can leave at any time. The lock-up terms are None; withdraw at any time, so the staking position is not tied up for a set period. The 3% to 5% return is therefore the main thing to weigh, and rates can move with the market.

How do I fund the account?+

Fiat deposits run through card and bank. Bank transfer is the most common method in this ranking, at 88.9%, with card at 66.7%. Card suits everyday top-ups, while a bank transfer suits larger sums.

What kind of app is it?+

It is a mobile wallet attached to a cex exchange, so buying and holding sit in one app from FUMBI, s.r.o. in Slovakia. Mobile wallets are 58.4% of wallets in this ranking, and the company has run since 2018.

How do I get help?+

Support runs on email, chat and phone, covering both live chat and phone alongside email and a help centre. A help centre is the most common support channel in this ranking at 85.7%.

Is there proof of reserves?+

fumbi publishes proof of reserves, which lets you check that customer holdings are backed. Brands in the wallets ranking that do the same make up 88.9% of the category, so it is common among peers rather than a differentiator.
