It seems most bitcoiners prefer cold hardware wallets over online platforms but why is that? Considering platforms like coinbase are FDIC insured and have the best security in the business, it seems much riskier to try to secure my bitcoins on my own. I feel my house burning down or some other accident destroying my wallet is much more likely than losing it on Coinbase. And if there is a breach in coinbase, I get it back... so what am I missing?? While I’m not new to owning bitcoin, I am new to learning about it. So I apologize if this is an annoying newb question.
No, you still have unsure answer if Coinbase is hacked. They can reason that all funds were stolen by the hacker. It's best to keep your bitcoins alone, on a hardware wallet. What you only need to keep are those recovery seeds, other than that when you're accessing the wallet, you'll be asked to confirm your withdrawals or addresses for deposit which you need to do and be done on the hardware wallet. You don't own your private keys in Coinbase and you don't have control over it.
