It's much more convenient. Can you please do that? I can't explain but it would be easier for me and many people.
We had a Shapeshift link once pointing to an ETH wallet, but we never saw any traffic to it. There's also the objective problem of using the cryptocoins to pay for our servers, as the hosting company doesn't accept (yet) crypto.
Anyway, since this has been requested again in the past, I'll pitch it to the team and create a wallet. Who knows, perhaps the sleeping cryptocoins will be worth millions in a few years... 8)
