changelly.com looks similar to shapeshift. There are some tutorial videos on youtube where whole process of exchange is shown. They don't say anything about KYC for the exchange transactions but require registration which seems easy. I haven't used it by myself yet so anyway it's better to check everything thoroughly before sending funds there. Personally I would recommend to use some exchange instead of that kind of services as the exchange rates there are usually not too good and they usually charge high fees.
I will take a look into this one and the one on the previous thread, because shapeshift rates are very high and the few times I have tried the transaction has not been completed for whatever technical reason on their side.
