Hey Ackza, I totally missed this. In general, this is more meant to facilitate funding for people who want to buy crypto and are having a hell of a time with exchanges or who want a quick and reliable way to put fiat into crypto with lower fees and a bit more safety than random ATMs (especially in the case of Steem and alts, since you don't have to trade through BTC/ETH/LTC to get them.)
There are sell options but they tend to be for much larger amounts via OTC. The USA is still a tricky market for regulation and services for Canada and International have been nailed down a bit more quickly. That being said, Netcoins has been working on getting their US services in place and has got some big plans coming down the pipe. If you're looking solely for a way to get quick, small amounts of cash, that's less so what this service is about, but I definitely recommend heading over to https://www.gonetcoins.com/ and reading a little more about it~
