Could we have a list of LEGITIMATE coin swapping/trading sites (whatever you call them) like Changelly and Shapeshift? NOT exchanges/trading sites like Coinbase, Bitstamp, etc. I know this is confusing, but I am not looking for that kind of exchange. BTW what do you call a site like Changelly to differentiate it from a site like Coinbase?
Also looking for the least expensive options, as some of these sites charge fees that essentially make it cost-prohibitive to trade your Bitcoin for Altcoins or vise-versa.
Also need to know if a site is closed to Washington, USA residents due to that stupid law they passed (I.E. Shapeshift), without approval of us registered voters!
I appreciate your help!
