You are lucky person who missed to see that things otherwise you have chance to lose your balance on Bitgrail. Which is huge lose and all this happen due to a terrible bug in code so many people crying because of this stupid job.
There was no bug in the nano code. The bug was due to the bomber misleading everyone that he was running a legit working exchange. You got taken by an exchange, and it isn't the first time exchanges try to pass their corruption/incompetence off as fault of the coin. Remember when mtgox tried to pin their crash on "malleability". Everyone now knows that was a huge lie, but suckers who leave coins on an exchange buy these lies because they can't handle the truth that they shouldn't have put their money in the hands of exchange operators.
Next time don't be lazy and set up your own wallet. There were and are plenty of options.
true words. Is there any plan on Hardware wallet integration?
