I don't really know if this exchange is a scam, it's a small exchange, but an old one.
ANYWAY: the website has been blocked for EU countrie for 7 days now and I have no news of the situation (just email asking me to wait without any technical explanations).
So... If you want to live dangerously and are ready to see your money kept behind a wall (or already spent in the streets of Santiago), then this website is for you
Personnaly I wasn't ready, and I still am not !
