Oh my God, I saw two news stories about crypto assets today, and I was completely shocked😨

One is a case in Ukraine, where someone was unfortunate after revealing they had crypto assets; the other is in the US, where a suspect was caught carrying a note with a password. I really want to ask—how does everyone store their private keys and seed phrases?

After being in the crypto world for so long, I’ve come to understand a key principle: **Owning crypto assets itself is not the biggest risk; the biggest risk is others knowing how much you have**. These incidents have shown me how important privacy protection is.

I'm feeling a bit anxious now and would like to ask some senior members a few questions—
1️⃣ How should seed phrases and private keys be stored to be truly secure? Is writing them on paper really okay, or should I use a dedicated cold wallet?
2️⃣ Which is more user-friendly and secure for beginners: custodial exchanges or self-managed wallets?
3️⃣ Are there any pieces of information I should avoid revealing in daily life?

I feel like I need to brush up on security knowledge, and I hope everyone can help me answer!💭
