Firstly, thank you very much for your reply.
IDAX is ok, wonder if Binance has their eye of Haven. Bittrex was a monster addition though.
Secondly, in reality, Bittrex has fallen deeply and has not still been the biggest ones in crypto exchange ecosystem.
I would like to see Haven Protocol on txbit.io exchange, which is a Netherlands-based and developed by Solaris project.
