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...
I understand what you are saying but coinbase does not say that they will guarantee everything and it will have certain limits, FDIC insurance has a limit of $250,000 and from what i understand that covers only US citizens and if you not from US you will not be having the so called FDIC protection.
The options is yours whether to take that kind of risk, as the saying goes, if you are not holding the coins in your own wallet then it is not your coins. Consider these limitations when taking these kind of risk.
