Daaaaamn, bomber (owner of Bitgrail) just made an announcement that "due to fraudulent transactions" he lost 17 million XRB and "has police investigating" and is freezing all activity with XRB including withdrawals. Welp, that's that, he done stole the rest of it. What a train wreck. I feel unaccountably lucky that they actually verified me and I was able to withdraw my XRB.
Or I guess he could really have been hacked or something... the site does totally suck.
So anyway, a lot of people on reddit seem to be blaming the Nano team, but my advice would be to hold on to your XRB as it's still the same working product that's the best of the fee-less near-instant transfer currencies. Also they have their own exchange now
