Basically it takes 8 days for your litecoin to be available (aka transferable) because otherwise you could just transffer your litecoin to another wallet and reverse the charge from your bank.
My guess is you are waiting 8 days for your bank transfer, not the litecoin. If you had money already in your account, or paid with a credit card it would be there immediately
I just used my credit card about 9 hours ago. I've had the money taken out of my credit card, but I've yet to see the coins appear in my wallet for sending or selling. It shows in coinbase that the transaction was "Completed", but I have nothing so far.
There's identity checks and SWIFT and lots of other possible points of slowness, but the fact that coinbase doesn't really circumvent them in practice is kinda the point being made.
Is this for real?
