Trading in this pair has been stopped
https://www.okex.com/spot/trade#product=hmc_btc and the volume has been reduced to 200 million to just 3.2 millions, does what it indicate ? has the whales left the market or it is rejected by the community ? there are many pump and dump signals on chart, what do you think, market is going to collapse or anyone just manipulating it ?
Looking at its weekly chart, it can still consider as good for day or short term trades. And what do you mean by
"stopped"? I see that there's a data in a 24H chart. However the same behavior as most of the altcoins today.
Don't know about some stuff circulated around that coin but since you mentioned that you saw lots of pump and signals on this coin does mean that this coin is part of those hype coins that dragged people on buying it. However, looks like their signals are not working anymore or many got wreck that's why what's left are those big whales who are just waiting for another wave.
For more reference, try to communicate in their main channel at any platform if there's any.
