Noticed that about midday they went from $630 to $670 with no trades to show for it .
I do not understand how their platform works but it is definitely not actual real trades based ,it must be set to track other exchanges .
I was willing to risk using their unknown platform because of the lower price but it looks like that boat has sailed now .
It takes me 5 days to get funds active on Hitbtc and 2 days to get funds to Bitstamp ,so for now Bitstamp is a better deal for me .
