算力控：Crypterra？不了，謝謝！

因為光從外面看根本是資訊接露不足，我接著嘗試註冊一個帳號進去看看有沒有更多的線索。不看還好，我想，這就是最後那一根稻草了，它是不收每日維運費的，在相對於其他同業，這麼便宜的價格下，竟然還沒有維運費，完全不科學阿。如果依照我在「如何挑選雲端挖礦公司？」一文中的判斷標準，這家 Crypterra 是完全不及格的了。而且，再偷偷跟你講哦，還有好多其它疑點哦，比如說，它沒有提供 2FA 二次驗證哦，這現在不都是最基本的嗎？又比如說，它只能用比特幣及萊特幣付款，沒有信用卡付款的選項，是不是信用卡公司那關過不了呢？

所以，Crypterra？ 不了，謝謝！至少目前為止，我不會貿然投入，或許再過一陣子，有更多的佐證資料出現之後，再重新來評估這家。不過，到時候可能每 TH/s 算力只要 89.6 美金這種超值優惠就不會再有了，這沒辦法，人生就是這樣，單純的就是要做出取捨，是吧。當然，如果你的風險承受能力很高，那你真的可以試試看，真的很便宜阿~
