從Bitcoin大跌看到甚麼?

可謂一石激起千重浪,包括Bitcoin在內的加密貨幣,上星期經歷過一個暴跌的一周,不少相關股票受到牽連,股價跌到四腳朝天。今次加密貨幣大跌市,或者可以比到大家多一點認識, 日後更加可以從容應對。

事實上,每當股市大起或大跌的日子,筆者都喜歡從中了解市場的動態,看看受到牽連,以及受到刺激的股份,從中了解相關的投資生態,讓日後投資更容易作出應變與及部署,今次加密貨幣大跌市亦不例外。

何解Bitcoin跌咁多?

先有Tesla 的CEO Elon Musk 彈弓手,話不再接受Bitcoin作為交易貨幣,因為唔環保,之後又有中國宣布加強打擊加密貨幣, 接二連三的壞消息,令到Bitcoin及一眾加密貨幣越跌越急,一星期內Bitcoin價值由43,500水平, 插水式跌到35,500美元水平,相關的資產蒸發金額數以十億美元計, 抵銷了不少今年以來的升幅,年頭買入Bitcoin,未至於輸錢,但只剩下微利。

Bitcoin是高風險的投資,大家入市前應該都預咗。Bitcoin及一眾加密貨幣的波動,比一般股票更加大。投資加密貨幣的買賣方式眾多,除了一般交易所,以及利用PayPay或證券行等地方進行投資,亦有不少透過未受監管的另類渠道,進行槓桿式和涉及衍生工具買賣,近年越來越受歡迎的永續掉期合約(Perpetual Swap)就是其中例子。

永續掉期加大炒風

永續掉期合約這種買期貨方式的投資,沒有期限,毋須實物交收,又可以小博大,所以越來越受歡迎,這類的買賣會加深Bitcoin等加密貨幣的大升大跌。大升固然開心,但大跌上嚟,屍橫遍野,俾人call孖展、 或者斬倉的局面四處可見。

有興趣了解這類買賣Bitcoin方式,推介這個簡單的短片(英文)What Are Perpetual Futures Contracts?

Bitcoin大跌累到早前接受Bitcoin作為交易貨幣的公司,例如PayPal(PyPl)、Square(SQ),以及加密貨幣交易所 Coinbase (COIN) , 股價跟隨大跌。有投資在Bitcoin的ETF,如 ARKW亦都跌唔少,不過基金公司好似並不擔心,反手增持相關股份及ETF。 隨此外外,大市也受到都牽連。

Bitcoin大跌最受惠的是黃金, 近年黃金作為資金避難所的角色,或多或少被這類加密貨幣所取代,兩者的投資有相互競爭的關係,當Bitcoin大跌,資金轉到黃金。

從兩隻追蹤Bitcoin的ETF: Grayscale Bitcoin Trust(GBTC)及追蹤黃金的ETF:SPDR Gold Trust ETF(GLD),可以看到股份走勢剛好相反。

這個大跌市或者讓大家多了解到這類虛擬貨幣投資的生態圈。 日後大家投資的時候,見到相關的股份大起或大落,也可以了解箇中的關聯。

投資市場最易賺錢就是有眾多大家未看得透徹的地方,資訊太流通,容易估到的話,股值好易計到及反映出來。加密貨幣的應用仍在演變當中,也有不少灰色的地帶,接受程度由散戶,慢慢被大機構所注視,投資只可說是有危亦有機,留意風險,以及生態圈的轉變,是投資這類高風險產品之道。
