There  are no incentives  to keep  the network secure,  this  means  that  there are more incentives  to attak the network, than to secure it.

Any  currency coin has already failed.. because it is volatile. I cant send 1 million in Nano   the price fluctuate and then I will end up   with 800k

Also  you dont pay fee  for the  transfer, but  you always  pay fee  to  stwitch  from  dollars  to Nano.


Nano has  not even  some kind of reward  for  the full node  runners.  IOTA  has  the monetization  of  the DATA  as form of reward  for full node runners
