Tried to catch Richie from bittrex on irc, haven't been able to get in contact yet. We will keep pursuing that route.
For now I think Cryptopia does a fine job. The HYP volume there isn't much different than the daily average was on Poloniex.
I will look into the code and see if I can figure out some optimizations that will reduce the resource consumption for those with many transactions.
Yeah the volumes are almost the same as Polo, just hope to see an higher price soon even if looks very hard!!
looking forward the wallet optimisation.
Thank you!
