Yes indeed, but on their site there is actually no official figure. They just say that they have been hacked, their bitcoin wallets breached and compromised and that is pretty much it. They haven't mentioned any amounts or whether or not their cold wallets are compromised as well.

So yeah, there is still hope for investors. But not much imo.

This is why chasing small profits can lead to big time losses sometimes, best to buy your own equipment if you're seriously into mining.
