I am a bit worried about quarkchain. The Binance listing news has pumped this coin up and the the volume is quite thin. I am afraid that if this drops it would be a free fall. Last few listings on Binance are iotx and theta as you mentioned. They did alright though and don't get me wrong because QKC is a pretty decent coin but I just feel that it might not be the best time to buy it.

Although for a long term buyer this would matter little. As you I can feel from you discussing the Quarkchain you are in for the long term. Hundred thousand tps is pretty good by all standards.

Two layered tech that can avoid 51% attack. Pooling has been discouraged and miners are incentived for their individual efforts. Thus the centralization at the secondary level can be avoided (major problems for bitcoin in this sense) - a definite game changer.
