Had the same with XVG the other day. I also am a small trader, and I can't really do the trades I want anymore..
As i've said before, it's simply because the price of reddcoin has been absolutely pumped to the moon and bittrex hasn't changed the minimum order value. Before the pump 3000 RDD was around 0.0005-0.001 BTC, which was close to 0.001, but now after the pump it is worth 0.002 btc and that's why everyone is complaining about it.
Read the support article. It's all written there.
Your minimum has to satisfy both the native currency requirements(aka 3000 RDD) and 0.001 BTC, for a trade to be valid and put onto the orderbook.
Where did you find that the native currency requirement on Bittrex for RDD is 3000 RDD?
I'm trying to find information on the native currency requirements for each market. Is there some sort of link of this information?
I've already read this article, but it simply states that there is a minimum quantity that varies based on the market..
