If you believe in BTC, mine on!
There's a reason why Bitmain is dumping s9's on the market....new stuff is incoming (and is probably mining already)
They are selling it for 2300 instead of 1400(November price). I wouldn't call that dumping.
Well, their competitors are also selling around the same price. I guess they going for more profit margins rather than volume.
