A crypto wallet is how you store, send, and receive cryptocurrency. Choosing the right wallet is one of the most important decisions in crypto.
Here’s everything you need to know.
The Golden Rule
Not your keys, not your crypto.
If someone else holds your private keys, they control your crypto. If the exchange fails (like FTX), your money is gone.
