PowerPool提案发起PowerIndex流动性挖矿计划 每月40万枚CVP奖励:PowerPool发起提案9投票，以解决PowerIndex构成问题，并提出了针对CVP的全新的流动性挖矿计划。投票包含3个项目：1.在过渡期间，Index的组成将保持相对不变，包括CVP，YFI，SNX，LEND，wNXM，UNI，COM??P和MKR。2.PowerIndex流动性挖矿计划。先前的计划是向Index流动性提供者提供每月200万CVP的奖励，奖励锁定一年。新提案是将奖励计划更改为每月40万CVP，其中50％的奖励立即对象，而另一半在接下来的10周内解锁。3.CVP的流动性挖矿奖励。当前有多个池，从Uniswap上的50-50ETH/CVP池到95-5CVP/ETHBalancer池，都可以通过流动性激励获得奖励。这稍微分散了一部分流动性，导致dex市场的流动性低于应有的水平。新提案议将所有奖励转移到50/50Uniswap奖池中。具体来说，该池每周将获得91,000CVP，而这些奖励将伴随10周的锁定期。[2020/11/18 21:13:57]

Coindesk：比特币三月份以来首次突破8000美元大关:Coindesk发表行情分析文章，比特币三月份以来首次突破8000美元大关，短期交易平仓推动大幅上涨，并可能很快突破8500美元。分析师称，短期币价迅速上涨，存在清算时间过短的风险。但市场成交量显示，反弹行情持续。分析师预测BTC阻力位在8500美元，并且短期看涨逆转已被证实。从小时图来看，不能排除回撤7600美元的可能，但只要收盘高于7000美元，都有继续上涨的机会。[2018/4/13]
