Ummm what abot this?
"If you are a United States resident, your Coinbase USD Wallet is covered by FDIC insurance, up to a maximum of $250,000."
Last time I checked USD was short for United States Dollar, the fiat currency... which isn't BTC... short for BitCoin...
The way I see it... your BTC is insured against theft etc, but only the ones that are held online which is only 2% of BTC held by CoinBase, bc it says so in their explanation. 98% is held offline... which has it's own merits... but not insured against anything...
And FDIC doesn't insure non-fiat currencies... so I also wonder which company insures CoinBase...
