CZ：交易所存储比自托管更安全，需平衡

It is statistically safer to store coins on exchanges than to self custody. 👇

A few thoughts:

Assuming the data is correct, my impression is Willy has always been a strong supporter for self custody.

Hack data is easier to collect on the CEX side, usually major news. It is harder on the self-custody side, where hacks, lost coins, etc are often not reported.

On the exchange side, some deceased exchanges drag down the data. Binance (and a few other exchanges) have always covered users for any CEX side hacks.

Not saying one is better than another. Different approaches have different risk profiles (and product offerings), and may be better suited for different people. A balanced approach is probably best.
