For earning passive income in the crypto space, you might consider staking or lending. Staking involves holding a cryptocurrency in a wallet to support the operations of a blockchain network and earn rewards. Coins like Cardano (ADA), Ethereum (ETH), and Polkadot (DOT) offer staking opportunities.
Lending platforms allow you to lend your crypto assets to others in exchange for interest payments. Platforms like Celsius, BlockFi, and Aave offer lending services, allowing you to earn interest on your deposited cryptocurrencies.
Always remember to research the platform thoroughly, consider the associated risks, and only invest what you can afford to lose.
