网上有很多种比特币云挖矿的服务，楼主经过一些调查之后还是最喜欢Hashflare。
相比于其它的比特币云挖矿服务，Hashflare主要有以下几大优点：
- 当你与Hashflare在网上签订好协约之后，挖矿马上就开始啦。24小时内你就能看到第一笔比特币到账了。很快很赞。
- 值得信赖。Hashflare算是一家历史悠久的比特币云挖矿了，大家都还蛮信赖的，支付也都很迅速。这一点是我考虑比特币云挖矿时很看重的一点，毕竟不想被骗嘛～
- 数据透明清晰。Hashflare有一个很漂亮的dashboard，上面显示了每天挖矿的情况，比如每天挖矿的收益啊，之后的预测啊，之类的。而且，你可以自己个性化用那个pool来mine，每天可以改一次的噢～ 你也可以找到自己比较喜欢的组合之后稳定下来～ Hashflare 没有任何隐藏的费用，每一笔交易或者收益都是清晰透明的展示给你的，让人很放心。
楼主买了一年的SHA-256的合约，目前为止体验很赞。两三个月内应该能拿回成本吧，之后就是纯收益啦：）
