继以太坊创始人 Vitalik Buterin 鼓励支持PoW的矿工转向以太坊经典（ETC）之后，DCG（Digital Currency Group）创始人也作出了类似呼吁。 8月6日，Digital Currency Group创始人兼首席执行官Barry Silbert发推特称，“我们全力支持ETH PoS，除了ETC，我们也不打算支持任何ETH PoW分叉。ETH矿工应该将算力转移到ETC，以实现长期收入最大化。 事实上，据2miners数据显示，自7月以来，ETC全网算力大幅上涨，从20Th/s附近一路涨至31.94Th/s，涨幅超50%。截至发稿时，ETC全网算力为30.06Th/s。 
另据miningpoolstats数据显示，ethermine.org、2miners.com、hiveon.net、 f2pool.com、poolin.com为ETC主要矿池。 
此前，受ETH合并以及矿工转移影响，ETC出现过短暂时间的暴涨。不过对于此种情况，部分业内人士并不看好。 Messari分析师表示，以太坊合并叙事不会推动ETC的持续上涨，ETC可能会在合并前几天飙升，但它没有长期上涨动力。 Messari表示，以太坊挖矿目前占图形处理单元(GPU)挖矿收入的97%，每日收入为2400万美元。而以太坊合并后，矿工将被迫出售他们的设备或改用ETC挖矿，目前ETC占GPU挖矿收入的2%，每日净收入约为700,000美元。这种盈利能力的巨大差距意味着，即使“有意义的部分”矿工迁移到ETC，挖矿难度也会急剧增加，并使许多矿工无利可图。 根据Messari的说法，以太坊经典的活跃地址数量不到Cardano的一半，该网络目前的发展水平不到以太坊和Cardano的十分之一，自2018年以来交易量没有出现有意义的增长。Messari称：“归根结底，价格应该与网络使用和潜在的经济活动有一些基本的联系，不幸的是，对于ETC持有者来说，两者都没有。” 加密KOL 0xAA表示：“ETC是接不住ETH矿工的算力的。对矿工最有利的方案就是在以太坊主网转PoS的时候进行硬分叉，搞出一条ETH-PoW，比现在的ETC链有价值的多。毕竟现在以太坊生态比ETC分叉的时候丰富太多了。 Messari分析师Dunleavy发推特表示，多年来ETC链上交易量和用户基本没有变化，应用程序不存在。从基本指标来看这条链没有任何变化，开发者活动也没有产生有意义的改变。97%的GPU挖矿收益来自Eth，2%来自ETC。 ETC的每日rwd约为70万，而Eth为2400万。如果矿工最终迁移到ETC，哈希率将大幅上升，导致采矿差异增大，将大部分矿工挤出美元盈利，想保持盈利的唯一方法是ETC价格上涨。 来源：金色财经 |
