maybe you should leave these things to be on the resources such as wikis, etc instead of trying to define them yourself and make a topic about it. in the first lines you already have multiple mistakes and they don't stop there. for example:
Cold Storage - Keeping a reserve of Bitcoins offline (such as on a USB).
you don't keep your bitcoins offline you keep your keys offline.
and the example is better be a paper wallet rather than a USB.
Confirmation - A Bitcoin transaction is considered confirmed when it reaches a certain amount of blocks deep.
that is the definition of a fully confirmed and irreversible transaction not the definition of "confirmation". confirmation means the transaction is included in a block.
Cryptography - A method of storing and transmitting data in a specific form so that only those for whom it's intended can read and process it.
i don't know if you are translating things or just write based on your own understanding but this is completely wrong. Cryptography has nothing to do with "a method transmitting data"!
