北京时间2016年11月11日，比特大陆旗下的比特币云 挖矿平台算力巢（hashnest.com）新推出 PACMIC 第五期合约。前四期PACMIC合约均已售罄并完成收益结算。

这款产品的英文名字，叫做PACMiC(Payback AcceleratedCloud Mining Contract)，也就是“加速回本云挖矿合约”的意思。加速回本云挖矿产品与其他云挖矿相比，回本速度大大加快。

   PACMiC的购买方式为每份1BTC，每份合约有6TH/s的算力。用户在支付成功后，合约即刻生效。合约生效后，用户就开始享受挖矿收益，其来源是6TH/s算力的挖矿产出，根据Antpool的PPLNS方式足额获得收益。而算力的维护费、电费等，都由比特大陆负责承担。每次分配的现金流时，先按照0.45聪/比特币/秒计算应该由用户分享的利润，扣除这部分利润后的剩余部分，则用于归还用户投资本金。用户的全部本金得到归还之后，合约结束。

  首先，PACMiC，100%的产出都先行分配给用户，使得用户收回投资本金的速度大大加快，投资风险被大大降低。而一般的云算力产品，其产出的40%～90%都需要用于支付维护费，用户的净收益只有挖矿产出的10%～60%，导致回本速度较慢；其次，加速回本云挖矿产品，每BTC就能够参与5T算力的投资，回本速度进一步提升。

例如，用1000 BTC可以购买到6000T=6P的算力合约，按照目前难度，第一天就可以得到约5.6BTC的本金返还，还收到约四千万聪=0.4BTC的收益。第二天，如果ANTPOOL的运气相同，用户收到的资金流入金额不会变化，只是其中属于利润的部分会比第一天略少，而属于本金返还的部分会增多。

PACMiC发行后，用户不再需要担心高昂的电费和飙升的难度，挖矿将成为既充满乐趣又风险较低的投资行为。 对比：矿机挖矿、算力挖矿与PACMiC挖矿



由于今年7月比特币产量减半，大多数比特币理财产品都减半了利率，但PACMIC仍然维持前几期的回报率水平。PACMiC非常适合追求稳健投资的挖矿爱好者。
