中國大陸政府在5月起強力禁止市民進行加密貨幣(挖礦)的行為，並在9月24日由中國人民銀行、國家網信辦、最高人民法院等10個部委共同發布有關加密貨幣挖礦監控的法律；《關於進一步防範和處置虛擬貨幣交易炒作風險的通知》，將與加密貨幣有關的業務活動定義為非法的金融活動，並且強調對於虛幣買賣、發行（ICO）、非法集資等服務「一律嚴格禁止」，有關大動作的原因據聲稱是因為要避免因挖礦造成大量耗電並引致社區供電問題。因為中國大陸長期以來都是比特幣挖礦重鎮，根據過去的統計，全球約有65%至75%挖礦活動都在大陸，所以當時推出法律造成加密貨幣大跌。
但根據360政企安全集團在11月公佈的最新數據顯示，中國境內挖礦行為減少未如政府預期，平均每日仍有最少10.9萬個「礦」在中國境內運作，其根本原因其實十分簡單；因為就正如(·托·約·登寧《工聯和罷工》１８６０年倫敦版第３５、３６頁）中的一名言所說：資本一旦有適當的利潤就會大膽起來。如果有10%的利潤，它就保證到處被使用；有20%的利潤，它就活躍起來；有50%的利潤，它就鋌而走險；為了100%的利潤，它就敢踐踏一切人間法律；有300%的利潤，它就敢犯任何罪行，甚至冒絞首的危險。而比特幣和以太幣等貨幣價值極高，平均挖礦進行6個月後就會(回本)，之後所赚的都是利潤。另外是加密貨幣交易提供了一條走資渠道，讓大陸內的市民有辦法繞過大陸政府對外匯流動的嚴格監管。
