I am accumulating NAV still and adding to my bag which I have been staking with for the past 6 months. Staking has been working really well and brought me some good rewards so far. It's great to earn rewards just for keeping my NAV in my wallet..
I don't really know why people worry because the price falls a little bit. NAV is obviously a safe investment and long term the only way is up if the Devs continue their fantastic work. I think the recent short term correction is most likely over now and combined with the recent bitcoin downward move and the technical indicators I think it's nearly time for a move upwards again.
Bottom line of it is I am holding a considerable amount of my tradeable funds in NAV because I really do believe in it and it is a very safe investment and in the long run will make good returns. There are a lot of other altcoins trading on POLO which have the same or less features and far worse developers that are worth a lot more money. You don't have to be a genius to realise that NAV is very undervalued and is overdue its time for a big rise. People are now warming to this hence the recent huge price increase.
Keep up the good work NAV
