There are lots of hoops I would need to jump around if someone would send be US dollars. Those would be frozen in my bank account, I would need to get an official papers (contract or something like this), translate it to the local language, notarize it and prove that those moneys are not from laundering stuff. And even then I might be denied to get those money if those papers were unconvincing.

With Bitcoin it just works with 0 issues. Also I don't need to pay taxes which is good thing as I don't like this government and don't want to fund it.
