Is there any way to see the volume that the site is doing? Would be helpful for investors / potential investors
You can see the statistics in the bottom of the site. It shows you exactely how much have been wagered so far, and how much profit the investors have made so far.
Joseph is exactly correct. To make it easier for you here is what you are looking for.

functioning well maybe it will take some time to recover and gain some good profits.
It will take quite a while to recover such a huge amount, especially if the volume is not huge and whales are not around. But who knows... perhaps tonight a big player might go crazy and dispose of a big sum. If you think the house has reached its minimum, then it is a good time to invest on it.
