3. Encrypt your wallet.
After creating your wallet, you should immediately encrypt your wallet with a strong password. A strong password is one that is greater than 15 characters and uses a combination of uppercase letters, lowercase letters, numbers, and symbols. Mix acronyms, favorite beverages, quotes, numbers, and a favorite symbol to create a secure and memorable password. For example, MISESyankee24$WaTeR>>
