Why is the 24H volume so low
This is hard to approach since what do you consider a low 24H volume? The 24H volume is now around 2-300K USD and it topped out at 3-4M USD at the ATH. The market cap of the coin is around 40-50M currently. If we just randomly look at some coins in that area: CloakCoin, Hive and Decision token the 24H volume is very similar. CloackCoin and Decision token are slightly higher at 3-400k USD but I would say the difference just depends on popularity at the time. As for CloackCoin it is already listed on Bittrex which helps drive the volume a little higher.

I think that the volume is not overly low for a 40M market cap coin that has yet to be listed to Binance or Bittrex but please elaborate on your question and I will have a deeper look.
