Yesterday, a friend's wallet was stolen from the coin exchange. Fortunately, it was not a lot. More than 20,000 yuan is not a small amount. The money earned from the hard work of coin exchange was emptied by hackers in an instant. It's really annoying.

Let's popularize the common sense of security in the cryptocurrency circle. First of all, I suggest you take a look at this blogger, who often shares some security knowledge.

1. The wallet for coin exchange, the wallet for receiving airdrops, and the main wallet must be separated.

2. TG must also be separated. The TG for receiving airdrops and the TG for coin exchange must be separated.

3. When using bot to coin exchange wallets, don't leave too much funds. You can transfer the money you earn at any time.

4. Ensure the security of your TG account, try to open a membership, and turn on "Do not allow anyone to pull you into the group" to avoid being pulled into some fake groups.

5. In the security settings of the TG account, turn on two-step verification and password lock.

6. Make sure that you are using your TG registered mobile phone number.

7. The exchange account must turn on multi-step verification and Google verification.

8. Friends who operate X accounts should also enable Google verification to avoid sending phishing links after their X accounts are stolen, which may harm their fans.

I am a veteran who has been in the Internet for 20 years, and I am trembling with fear in the cryptocurrency circle. Don't be too extravagant.
