好吧,这是我在Slush's pool上对Bit-coin收入的第一分钱. 回想起来,2013年平安夜开始到今天,将近3个月没日没夜窝在这个矿里挖矿 从最开始的集成显卡挖,买了显卡挖,加了显卡挖,使用手机挖,使用树莓派挖 甚至是加上所有可以使用的CPU挖,到最后现在使用的蚂蚁USB挖~~~ 其中的苦与乐只有自己知道呀! 对于Slush's pool我还是忍不住要吐槽一下:经常莫名其妙的无法访问,俗称"矿难":界面丑陋… 不过,作为世界上第一个BTC矿池,Slush's pool还是值得…

我想从理清自己所说被动收入的含义,开始创作此被动收入系列文章. 我更喜欢把被动收入较宽泛地定义为,甚至当你没有主动工作时,仍可赚取的收益.被动收入的另一个名称是剩余收入. 相比之下,当你停止工作时,通过主动收入赚得的金钱也将停止流入你手中.假如你靠薪水生活,那么当你辞去工作或被解雇时,很可能就没人再付你薪水.你也许能得到一笔遣散费来帮自己转换工作,但除非你一直现身工作,你的老板将不会继续付你薪水. 与之相似,若你是为付钱给自己的客户完成合同工作,假如你停止这种工作,也将不再获得报偿.你在合同工作…
