I heard Graft project will be having a pre-sale again after it's success last September I have few in my NEM wallet but I haven't use them yet, I also don't check them since the day I received them I don't know if it's market price is good today just in case I will visit my wallet. I don't give much focus to them because I'd rather invest in ethereum especially now that the value keeps increasing but just in case graft will be successful I will be happy collecting my profit from it.
Qchain has just solved the issue. They made a unique coin based on two platforms. Personally, I have not seen anything like that. And I think that this decision was not easy for the team and developers, but in the near future it will give it's bear fruit.
