Nullex (NLX) is now on Cryptopia, Swap Completed there.
You can now benefit of trading there, Put buy order on a lower price, I guess the price will fluctuate due to newly open trading and so your buy orders may be fulfilled at a very low price all of sudden and then the price gets settled. So have a good chance of getting the benefit.
My order of 0.1 BTC all of sudden fulfilled at 160 satoshi and currently, the price is around 300satoshi. I hope more fluctuations may happen.
Good Luck!
