What a mess with Nav 2.0 and 1.0
I tried to send from trex to polo but then I realised that these two aren't compatible
But why 1.0 are worth more???
That won't work...trex is running NAV 2.0 chain whereas polo still on 1.0, you can only exchange between compatible versions of NAV blockchain, i.e.
Polo -> Cryptopia and Bittrex -> Alcurex
Insofar as your question as to why 1.0 are worth more (that depends on the exchange), actually worth less on Cryptopia's buy side. Regardless, impossible to say why 1 or more people pushed it so high on polo earlier today.
