You should be just fine if you keep Bitcoin in hardware wallet (Trezor, Passport, Bitbox, Keystone...) and keep seed phrase in secure way offline, but best protection is certainly using multisig setup.
I am surprised that Luke didn't use Multisig, that is must have for anyone that is dealing with larger amount of Bitcoin, like in his case with over 200.
Using dedicated computer for anything related with Bitcoin is also good, but I think Luke was targeted for some time and they just waited for the right moment to attack.
Thanks for the tip. Will definitely look into it.
Let's assume Luke is being truthful and did get hacked. How hard is it going to be for the hacker to turn those BTC into cash? I saw a tweet where CZ said if they are moved to Binance they will be frozen. I'm assuming other major crypto reserves will do the same since an online footprint has been left behind?
Considering this is a Bitcoin developer we are dealing with, they are going to take this matter very seriously. It's not like he's going to get stonewalled by endless layers of customer support bots & human reps like us ordinary plebs do...
