Entering the crypto space for the first time is often where mistakes happen most easily, especially when it comes to wallet management. I've been in this circle for several years and have seen too many people suffer massive losses from a single operational error. Today I'm going to organize my experience and lessons learned.

**About Device Selection**

First, understand that your wallet device is your vault. Using a "clean" phone to manage assets is a must——ideally one with just a SIM card and no social media software installed. If conditions permit, an Apple phone is the first choice, and you must factory reset it or get a brand new one before use. This isn't overkill; it's about isolating risks from the source.

**How to Download Your Wallet**

Once your device is ready, the next step is wallet installation. Download top-ranked products from the official app store using a US account——never cut corners by downloading from browsers or links sent by others. Fake wallets are everywhere, and one careless move makes you someone else's ATM.

**Protecting Seed Phrases and Private Keys is Most Critical**

When you actually start creating your wallet, remember these two points: First, remove your SIM card and turn on airplane mode before registration to take your phone completely offline; Second, and most importantly, your seed phrase must be written down by hand, absolutely not screenshotted, photographed, or stored in the cloud. That string of words is your asset's lifeline——once leaked, it's permanently lost.
