Wallets: hot vs cold, and protecting your seed phrase

Video coming soon
Educational content, not investment advice. Nour explains how markets work. She never tells you what to buy or sell.
A crypto wallet does not hold coins; it holds the keys that let you move them. Whoever has the keys controls the money.
- The private key cannot be changed or replaced; lose it and you lose access permanently.
- The seed phrase is a word backup of your wallet: store it securely and never share it, never as a photo or in the cloud.
- Hot wallets are online and convenient but exposed to cyber threats; cold wallets are offline and generally safer but can be lost or damaged.
- Leaving coins on a platform means trusting it: if it is hacked or goes bankrupt you may lose access.
