To choose a crypto wallet, decide first who holds the keys (you or a custodian), then match the wallet to how you use crypto: a hardware wallet for long-term savings, a software wallet for frequent transactions, and multi-signature for large or shared funds. Confirm it supports your blockchains and offers a standard recovery backup.

Custodial or non-custodial: who should hold your keys?

A crypto wallet does not store coins; it stores the private keys that authorise transactions on a blockchain. The SEC's December 2025 investor bulletin on crypto asset custody frames the first decision as self-custody, where you manage the keys, versus third-party custody, where a company manages them for you. Our explainer on how crypto wallets work covers the mechanics.

QuestionNon-custodial (self-custody)Custodial (third party)
Who holds the keys?You, through a recovery phraseThe exchange or custodian
If you forget a passwordRestore from the recovery phrase; no one else can helpAccount recovery through the provider's identity checks
Main riskLosing or leaking your recovery phraseProvider failure, frozen withdrawals, account takeover
Questions to askIs the backup standard (BIP-39)? Is the code open to review?Are assets segregated? Are they lent out? Can you verify holdings?

The collapses of FTX and Celsius in 2022 showed the custodial risk: customers' withdrawals were frozen and recoveries ran through multi-year bankruptcy cases. Self-custody removes that counterparty but makes you the only line of defence.

Hot wallet or cold wallet: which do you need?

Wallet typeWhere keys liveBest forMain weakness
Mobile or browser walletPhone or browser extensionSmall balances, payments, appsMalware, phishing, fake extensions
Desktop walletComputerPower users, Bitcoin full nodesExposed if the computer is compromised
Hardware walletDedicated offline deviceLong-term savingsCost, setup effort, still needs careful signing
Multi-signature walletSeveral devices or peopleLarge, shared or business fundsMore complex to set up and recover

Most people use two: a hardware wallet for savings and a software wallet for spending. Our hot vs cold wallet comparison goes deeper on the trade-offs.

What security features should a wallet have?

  • Standard backups: a BIP-39 recovery phrase (12 to 24 words) or SLIP-39 Shamir shares, so you are not locked into one vendor.
  • Optional passphrase support for an extra layer if your written phrase is found.
  • Clear signing: the wallet shows the recipient, amount and type of approval in plain language, on the device screen for hardware wallets.
  • Reviewable code: open-source software or published independent security reviews, plus a public record of fixing reported issues.
  • Active maintenance: regular firmware and app updates from a team with a track record.
  • Multi-sig compatibility if you may later want to combine devices.

Does the wallet support your blockchains and tokens?

Network support matters as much as security. USDT, for example, is issued on several blockchains, including Ethereum (ERC-20), BNB Smart Chain (BEP-20) and Tron (TRC-20). Ethereum and BNB Smart Chain use the same address format, so a single EVM wallet can receive on both, but you must pick the matching network when sending. Bitcoin uses a different format and needs a wallet that supports it. Our guide to BNB Smart Chain and BEP-20 tokens explains that network.

Which wallet setup fits your situation?

Your situationSensible setup
First purchase, small amountA well-established non-custodial mobile wallet, with the recovery phrase written down offline
Holding for years, meaningful amountHardware wallet bought from the manufacturer, plus a metal backup
Frequent use of decentralised appsHardware wallet for savings, separate software wallet for app activity
Family, business or very large fundsA 2-of-3 multi-signature setup across separate devices and locations
You prefer not to manage keysA custodial service, after checking regulation, reserves and withdrawal terms

How do you avoid fake wallet apps and tampered devices?

  • Download apps and extensions only through links on the developer's official website, and check the publisher name in the app store.
  • Buy hardware wallets directly from the manufacturer or an authorised reseller, never second-hand.
  • A genuine device generates a new recovery phrase during setup. A device that arrives with a pre-printed phrase is a scam.
  • Never enter your recovery phrase into a website, form or chat to "activate", "validate" or "sync" a wallet.

Once you have chosen, follow our step-by-step wallet setup guide, then apply the wallet security checklist.

Withdrawing from Wealtii?

Wealtii pays withdrawals in USDT on BNB Smart Chain (BEP-20) to an external wallet, so the wallet you choose must support BNB Smart Chain. While invested, your fund assets are held by Wealtii as custodian, 1:1 in a public Gnosis Safe 3-of-3 multi-signature vault. Wealtii is not regulated and has no insurance; see how Wealtii deposits and withdrawals work.

Frequently Asked Questions

What is the best crypto wallet for beginners?

There is no single best wallet. For small amounts, a well-established non-custodial mobile wallet that supports the blockchains you use is a sensible start. Once your balance is more than you could afford to lose, move long-term savings to a hardware wallet bought directly from the manufacturer.

Do I need a hardware wallet?

You need one when you hold crypto long term and the amount matters to you. A hardware wallet keeps private keys on a dedicated device, so malware on your computer cannot copy them. It does not stop you approving a malicious transaction, so you still need to read what you sign.

Can one wallet hold Bitcoin, Ethereum and BNB Chain tokens?

Many wallets support several blockchains, but support varies by app and device. Ethereum and BNB Smart Chain share the same address format, so one EVM wallet can hold both, while Bitcoin uses a different format. Always confirm the exact network before sending, because tokens sent on an unsupported network can be lost.

What happens if my wallet company shuts down?

With a non-custodial wallet that uses a standard BIP-39 recovery phrase, you can restore your funds in another compatible wallet, because the keys come from the phrase, not the company. With a custodial service, access depends on the custodian, its terms of service and the insolvency law that applies to it.
