A crypto wallet does not 'hold coins' like a physical wallet. It holds keys. Your public key/address is like an account number you can share; your private key (often backed up as a 12–24 word seed phrase) is the secret that authorizes spending. Whoever controls the private key controls the funds.
This is the most important security idea in all of crypto. There is no 'forgot password' and usually no chargebacks. Self-custody gives you full control and full responsibility.
Safety rules
- Never share your seed phrase. No legitimate service will ask for it.
- Write the seed phrase on paper/metal; never store it as a screenshot or in email.
- Beware impersonation, fake support, and 'too good to be true' offers.
Key takeaways
- Wallets store keys, not coins; the private key is everything.
- Self-custody = full control and full responsibility.
- Seed-phrase hygiene prevents the most common catastrophic losses.
