Do I need a different wallet for each cryptocurrency?

Not usually. Modern wallets like MetaMask, Trust Wallet, and Coinbase Wallet handle dozens of EVM chains. You will, however, need a separate wallet for non-EVM ecosystems — Phantom for Solana, Keplr for Cosmos, Xverse for Bitcoin and Ordinals — because the underlying address formats are different.

What happens if I lose my phone or hardware wallet?

Nothing, as long as you have your seed phrase. Install the same wallet app on a new device, choose 'Restore from recovery phrase', and enter your 12 or 24 words. Every account, balance, and history reappears. Without the seed phrase, the funds are unrecoverable.

Is a custodial exchange wallet good enough?

For small amounts you trade actively, yes. For long-term savings, no. Custodial accounts can be frozen by the exchange, seized by regulators, or wiped out by an exchange failure (FTX, Mt. Gox, Celsius). The phrase 'not your keys, not your coins' exists because it has been proven repeatedly.

Can someone steal my crypto if they only know my wallet address?

No. The wallet address is a public identifier, similar to an email or bank account number. They can see your balance and transaction history (because most blockchains are public), but they cannot move funds without the private key or seed phrase.

How much does a crypto wallet cost?

Software wallets are free. Hardware wallets typically cost $50 to $200, with Ledger Nano S Plus and Trezor Safe 3 being the most popular entry-level options. Network fees (gas) are paid per transaction and depend on the chain — fractions of a cent on Solana, dollars on Ethereum mainnet during congestion.

Should I use the wallet built into my exchange app?

Exchange-branded 'wallets' are sometimes custodial accounts in disguise. Coinbase has a true non-custodial product called Coinbase Wallet (separate app), while the main Coinbase app is custodial. Read the wallet's own description: if it shows you a seed phrase you must back up, it is non-custodial.
