If this site is actually working, probably take advantage of it already while they currently don't require KYC; because it's very likely that they will require KYC soon if this site gains traction and enough publicity to get the attention of the fed. Pretty much like what happened to ShapeShift. Since it's a pretty not-so-well-known service though and because of the fees being a little to high for me(even higher than ShapeShift like you said) personally, I'd stick with Binance.
Same goes for similar services as well but its just a norm for these FEDs behind their a**es if they do already making out too much noise.
Ive been using flyp.me when it comes to instant exchangers but this one isnt bad either.I might tried this one optionally.
They are indeed taking advantage yet most famous instant exchange are requiring KYC now.
