Is bad for XRB that bitgrail has been hacked/stolen funds. I think next month the price should go up. Maybe there should be blocked the stolen funds from bitgrail if that has been posible.
In the case of stolen NEM from CoinHouse few weeks ago, the NEM team used build in api functionality to "mark" and trace all the accounts the hakers used to move and try to lose the trace of the stolen NEM. Hopefully the same can be done for NANO.
