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.
We want privacy for our own that is why some of us are here in crypto and also you should know that "Not your Keys, Not your Coin" .
You could use whatever platform or wallet you want but always remember those words you don't have total control on your crypto and they are monitoring those transaction.
And not to mention that if we would have some fork in BTC you wouldn't get your reward in those centralized wallet like coinbase.
