Coinbase offers this vague promise on their website that they are
"partially insured", but does anybody know what that actually means? If they are hacked and the addresses get destroyed or stolen (we'd never know which), then... where would that leave Coinbase depositors?
Although the Coinbase exchange offers insurance, elsewhere I saw, that there is no guarantee for users about their assets, in case of hacking or theft.
This is stated as follows.
Your fiat wallet is not a deposit, transaction, cash management, or investment account, which means that any cash balance you hold on Coinbase is not insured, protected, or covered by any collateral, including (but not limited to) FCS.
And elsewhere also mentions the same thing.
Coinbase is not a depository institution, and your USDC balance is not a deposit account. Your USDC balance is not insured by the Federal Deposit Insurance Corporation (FDIC) or the Securities Investor Protection Corporation (SIPC).
From some data that I read about security or insurance made by Coinbase, the conclusion:
It’s important to note that while Coinbase and other cryptocurrency platforms implement security measures, by the nature of a cryptocurrency exchange, they are all centralised entities. Therefore, the risk of a hack or cybercrime exists.
So whatever system is implemented by the exchange, risks still exist, so consider the risks that might occur to our assets on any exchange.
