OP posted on March and the price of Nano is around $8.84 and look on how far it dipped.
The price of Nano now is $1.17 so this is a best buy not only for OP or to anyone that's interested with this coin. The market has been low for several months so those early months were better if we're going to assess it.
nano down right now...all alt is down so what we can do is just hold on
Don't forget that you can also buy while you can see it going down.
