I have only browsed this thread, but from what I gather so far:

the BTC ARBS admins only offered to pay back the stolen BTCs AFTER some users managed to gather some information about their real identities. They now claim they were hacked and are now trying in good faith to get us all our money back. The timing could of course be a coincidence.

I am having a hard time believing this due to the extremely shady practice of legacy accounts and those infinitesimal transfers that were done every other day. That was clearly done in order to buy some time and gather more funds. I suspect the same practice now. They'll pay off the most vocal critics and especially the ones that found their personal information, meanwhile figuring out how to stay off the radar.

So btc-arbs should come forward with a clear payment plan. I am 99% they don't have all the BTCs that were invested with them, so some people will not receive everything. Ideally, we all get the same percentage of what we invested. But this process should be transparent and we should all be aware of it.
