This lesson is about custody, not about what to buy.

  • Your private key authorises transactions; it cannot be changed, and if you lose it you permanently lose access (SEC).
  • A seed phrase restores your wallet; write it down safely, never share it, don't store it on a computer.
  • Self-custody puts responsibility on you; third-party custody means trusting a platform that could be hacked, shut down, go bankrupt or lend out assets.
  • Hot wallets are online and convenient; cold wallets are offline and more secure from online attacks but can be lost.
  • Transactions can't be reversed — verify addresses and test with small amounts.
