This section explains how a crypto wallet actually works, from the app on your phone to the hardware device in a drawer, and how to keep what is in it from being stolen. It is written for US investors who hold more than they would be comfortable losing and want a clear, tested way to protect it.
For small amounts you trade often, an account at a regulated US exchange is reasonable, but understand that crypto there is not covered by FDIC insurance the way bank deposits are. If the platform fails or your login is compromised, recovery is uncertain. Once a balance grows into money that would hurt to lose, move it to a wallet you control. A hardware wallet from an established maker costs well under $100, which is cheap relative to the risk it removes. Buy direct from the manufacturer, never second hand.
