Coinbase purchase bitcoin transaction pending, why is it painfully slow to purchase I have purchased bitcoin using coinbase app 3 hours ago and the transaction is still pending. Is it usually this painfully slow to transact on coinbase?
Coinbase is a service, your transaction is happening on their internal servers, not the bitcoin network. If you choose to withdraw your bitcoins to an external wallet, that would involve a transaction on the bitcoin network. 

So the delay depends entirely on Coinbase, during high volume times I would guess their order fulfilment is slightly slower. Your order will come through though!
