How do you verify wallets on coinbase with blockchain?

[adoni]

We have some btc accounts and our coinbase account is new

It's a couple of weeks old and it is monetized

We did a buy and its funded and it has been used to send out btc

Yet the address they give us for our 'wallet' when looked up at block chain shows 0

Anyone know how to verify the wallets on coinbase with blockchain to see they are in fact funded and are holding btc?

It's a web wallet, the address they gave you is probably for people to send to.

You don't actually have any bitcoins, they do. All you have is an IOU from them saying they will give you can spend X bitcoins and they will pay it.

You can't verify it so simply: coinbase.com controls the private keys (which control the money's movement on the actual blockchain) and will send money around as they wish, in order to do withdrawals when you ask and keep the bulk of their funds in secure cold storage. Instead, you have a balance which you can view when you log in, and when you request a withdrawal, they will withdraw that much money from any of their addresses.

If you want the peace of mind of being able to externally verify your balance (and other security concerns, like making sure another Mt.Gox doesn't happen to you, where malice or incompetence causes your money to be stolen/lost), you should control your own keys. See the clients at https://bitcoin.org/en/choose-your-wallet and note the warnings.

Coinbase gives you keys

Here's a key to sell or receive

But on the main account balance page they have an account number

IT DOESN'T EXIST on block chain

So coinbase isn't passing my sniff test

We created the account to do three things

a. accept money from our network services/products
b. to buy decent amounts daily
c. to transfer out money to our own wallets kept on electro and also on a core wallet

But I would like to see my existing balance I do keep on it to show up in a chain like my electro and core wallets do

Coinbase looks like fuzzy accounting to me

It works to buy from a trusted source, it works to receive, I'm not going to keep a big balance in it, my electro and core wallets are for that

But you would think when they say here's the main key for YOUR BALANCE it would show up

FUZZY ACCOUNTING A RED FLAG IMO

But a nice service to buy BTC from a trusted source and it is easy to interface with for ecommerce trans
