#钱包安全事件 Seeing this case is a bit hard to believe—Russian traffic police using violence to extract evidence and stealing tens of thousands of dollars worth of BTC, and they can still live to be sentenced to 7 years—that's quite crazy. But thinking about it carefully, this incident serves as a wake-up call for us copy traders.

Wallet security always comes first, no exceptions. I've seen too many experts directly wiped out due to improper private key management, no matter how good the returns look. Copy trading is not about blindly following; after choosing a trader, you must also protect your assets—basic actions like cold wallets, multi-signature, and regular checks on authorized addresses must be in place.

Honestly, money can be earned back, but once lost, it's truly gone. When I copy trade now, I set up position sizing based on risk preferences, with most funds stored in cold storage, only leaving the necessary amount on exchanges. Even if the trader I follow crashes, at least the principal remains. Another detail—don't put all your eggs in one basket. Diversify by following traders with different styles, which can spread both strategy risk and wallet attack risk.

These days, the biggest risk in trading isn't the market itself, but security incidents. Proper protection is essential to trade with peace of mind.
