比特幣挖礦被封殺 礦工們更高興了 利潤大漲

過去的兩三個月中，中國多處陸續封殺比特幣挖礦，此一波打壓影響了比特幣價格，目前最新價格為3.4萬美元，而5月高峰時可達6.5萬美元。

中國挖礦產出約佔了全球三分之二以上，全球最大的礦場關閉是否就會令比特幣衰落下去？現在判斷還為時過早，實際上由於比特幣挖礦被封殺，剩下的礦工其實並未受到多大影響，反而更受益了，因為隨著比特幣演算法的調整，現在挖礦的產出更高了。

中本聰設計比特幣的思路很高明，產出是固定的，挖礦的人越多，大家的難度就越高，收入會降低，反過來則是挖礦的人越少，收入可能更高，早期顯示卡挖比特幣的時候即是如此。

最近一個多月來，比特幣全網的算力減少了50%左右，但是上週演算法自動做了調整，挖礦難度降低了28%，之前完成一個區塊的挖礦需要14-19分鐘，現在只要10分鐘左右。

受益於此，挖礦的收益已經大幅增加，有人計算如果使用最新的礦機，以前每天的收益在22美元，現在可以達到29美元。

挖礦服務廠商Compass創辦人Whit Gibbs表示：我們預期Compass Mining客戶的挖礦盈利能力會更高，我們預估礦工的利潤將增加約35%。
