It seems that someone has bought a larger amount of NANO at Jul 18 and that push price to 3$, and daily volume was over 8 million $ at that day. Today we are back to 2.40 $ and yesterday trading volume is only 5.5 million $. Now I see Binance deposit problem (again), really is a shame that such coin have constant deposit problems and it is being advertised as instant&no fee...

Also NANO is now ranked at 43 place (coinmarketcap), to low considering that he was positioned in top 20 not so long ago.
