And why would you put money in there? 90% of all the people in here, even all those newbies who are always posting the same shit knows that bitgrail is a giant shit who is scamming everyone.
At the time people thought BitGrail was a reasonable exchange. If you wanted to buy Raiblocks/Nano, BitGrail was the place. The XRB team even promoted and recommended BitGrail as the best place to buy XRB.
The other issue is that people were trying to take their money from BitGrail for weeks. Their withdrawal system only worked a few days each month. So even if you didn't want to keep your coins there, you didn't have any choice.
