Generally, cryptocurrencies have a significantly smaller attack surface than traditional financial institutions due to their usage of blockchain technology. However, there are still some security vulnerabilities found in digital assets and the issues usually go back to the user itself. Missing keys are a common security issue in the crypto industry.
You should always ensure that your private key - which is the key you use to sign transactions and prove you own the related public key is stored securely and never gets shared under any circumstances. Remember - not your keys, not your crypto.
For newcomers, find a trusted and reputable exchange to store your crypto and leave the responsibility of storing the crypto to us. However, make sure you set a very strong password for your exchange account to prevent other parties from getting access to your account. We would recommend that you use a password that is long (at least 10 characters and above) and contains uppercase letters, lowercase letters, numbers, and special characters. You can also use a random password generator to create a unique password. Always ensure that your passwords do not contain any personal information.
An example of a good password would be: RagaMuffin6903$@@
