I think QRK has a glorious history of pure PoW. As long as it is a completely decentralized digital currency with pure PoW mechanism, it will win the trust of investors in the whole coin circle, and our community can also boldly publicize it.----------- However, as long as there is POS+MN, the reward of POS will be given to the exchange for questioning the existence of conspiracy of this currency, while the reward of MN will encourage the exchange to enjoy its success without making progress, and the reward of foundation nodes will be rewarded without effort!
