Anyways, in a 5 minutes video he posted on X which i will share below, he did mention always advising people to get a hardware wallet and store their bitcoins on it, meanwhile he himself doesn't own or use one, due to his confidence that he could never be hacked, but unfortunately, it happened, he got hacked.
It was his fault, hardware wallet was never wrong in terms of securing your coins.
Actually using and holding Bitcoin isn't that hard since we're already familiar about using mobile banking or digital fiat, so we should've understand about the basic digital security.
Using something that you're not completely understand is really bad, you can't just throw your money with closed eyes.
