Beware of that wallet, you could lose all the Nanos, if is not sync correctly!. I know people who have lost everything because of that crappy wallet. There is no official wallet yet for Nano, which is why it will not exceed $ 20, until someone serious, design a working and safety wallet. That is one of the weakest points of Nano. In addition, as it has no cost and few are behind its development, it has a very weak value. You have to understand that Bitcoin, for example, the great value it has is because there are millions of miners working day and night with a very valuable infrastructure, that is why it will always stay more or less up, but Nano being free, loses its investment value against other currencies. Beware of that  junkie/crappy (un-sync) wallet !  that is crap and it does not work!
