A wallet does not store your coins — it stores the key that moves them. Here is what actually differs between wallet types, and how to pick one without losing everything to the wrong choice.

Every hardware wallet keeps your keys offline — that part is solved. What differs is the security model, the coins supported, and how easy it is to make an expensive mistake. Here is how to choose and set one up.

Your seed phrase is the wallet. Storing it badly is the single most common way people lose crypto — and the two failure modes, theft and loss, pull in opposite directions. Here is how to balance them.

Same address, different chain. Token sent to a contract. Bitcoin format mismatch. Almost every permanently lost transfer comes from misunderstanding what an address actually identifies.
