this is already a very elegant variant to transfer steem.
with blocktrades.us it is more comfortable to do it because you dont have to sign up and do "exchange stuff". but it is a little bit more expensive.

your explanation is very good.
and once someone figured out how to do this it isnt really difficult anymore.
But i am pretty sure it will be even more easy in the next month to do it and in a few years you'll maybe dont need to use bitcoin or crypto exchanges.
