As a developer or project owner i would like to be able to withdraw funds from the contract so that I don't look silly for forgetting to add a withdraw function!
This might seem counter-intuitive to some but we have to define withdraw ourselves. If we do not define a way to withdraw the crypto sent to the contract it will be stuck forever. I'll spare you the gory details.
