Recently, I spent time systematically organizing the core knowledge of digital asset management, starting with in-depth wallet selection.

The difference between cold wallets and hot wallets is actually very important — cold wallets are stored offline and are more secure, suitable for holding large assets long-term; hot wallets facilitate trading but require risk prevention. Mnemonics and private keys are the true centers of authority; whoever controls these two can control your assets, so backups and safekeeping must be done meticulously.

Multi-signature mechanisms are considered an advanced feature; multiple private keys jointly authorize transactions, significantly reducing single-point risks. As for Gas fees, the hidden costs of on-chain transactions, they need to be flexibly adjusted based on network congestion.

From basic on-chain transaction security to DeFi beginners, this knowledge system basically covers the risk prevention and asset management methods that beginners must master. Keep studying, and prioritize safety.
