The month-long cryptocurrency slide continued overnight with ether, the cryptocurrency of the Ethereum network, falling below $100 for the first time since May 2017. Ether's value is down 93 percent from its January high above $1,400.

Bitcoin reached a 2018 low of around $3,500 last week. It's now trading at around $3,700, down 80 percent from its high of almost $20,000 last December.

There doesn't seem to be any specific cause for recent declines. Rather, the steadily declining prices seems to reflect a general decline of enthusiasm for the cryptocurrency.

Bitcoin's price has fallen more than 12 percent over the last 24 hours to $5,400, the lowest price for the popular cryptocurrency in more than a year.

Bitcoin's plunge is part of a broader cryptocurrency sell-off. Ethereum has fallen more than 15 percent over the last 24 hours, while Bitcoin Cash is down 18 percent.

Cryptocurrency markets are jittery ahead of a high-stakes "hard fork" of Bitcoin Cash. Rival factions are pushing different, mutually incompatible versions of the spinoff cryptocurrency, and the two versions are scheduled to create separate, competing versions of the blockchain starting on Thursday. The schism could create confusion among users and damage the reputation of the cryptocurrency.

A lawyer representing Charlie Shrem, the Florida-based bitcoin entrepreneur who was recently sued by Winklevoss Capital Fund over an alleged theft from five years ago of 5,000 bitcoins, has now fired back in the lawsuit.

In a Monday court filing, Shrem's attorney, Brian Klein, wrote that WCF's allegations are "nonsense" and that his client "engaged in no wrongdoing. Period."

As Ars reported on Sunday, Shrem was released from prison in 2016 after he was convicted for aiding and abetting an unlicensed money-transfer business by sending $1 million in bitcoins that ended up on the notorious drug website, Silk Road.

Two of the world's most famous bitcoin investors, the Winklevoss twins, have now sued a longtime figure in the world of bitcoin, Charlie Shrem.

Shrem was released from prison in 2016 after he was convicted for aiding and abetting an unlicensed money-transfer business—sending $1 million in bitcoins that ended up on the notorious drug website, Silk Road.

According to the new lawsuit—which was filed in federal court in Manhattan in September 2018 and only recently unsealed—Winklevoss Capital Fund (WCF) hired Shrem in late 2012 to purchase bitcoins on its behalf.
