this is pretty annoying:
DUST_TRADE_DISALLOWED_MIN_VALUE_50K_SAT

I don't like it, too.
To trade we need a minimum of 50k sat? OMG.
yeah trades need to be more than 50k sat BTC
I've never been trading lots of coins on Bittrex.
Can you please specify if that MIN_VALUE_50K_SAT was there since the Bittrex launch or it's a new spec for this exchange?
Thanks!
