As it is stated on the official website of the coin, Verge is a cryptocurrency designed for people and for everyday use, which aims to fulfill its initial purpose of providing individuals and businesses with a fast, efficient and decentralized way of making direct transactions while maintaining your privacy. However, the hackers did not find Verge fast enough and decided to increase the speed of blocks creation by conducting a mining attack.

As it was reported on Bitcointalk forum, April 4 was marked by a >51% attack on XVG which exploited a bug in retargeting in the XVG code. The attack was possible due to several bugs in the XVG code, which were exploited by mining blocks with a spoofed timestamp. The false timestamp was set to the blocks, and XVG "thought" the last block mined was one second ago. Basically, the hacker managed to mine one block per second.

The story did not finish on April 4, as on April 5 the attacker started again and mined about 12k blocks. The attacker started the new attack at around block 2014060 and stopped at block 2026196. According to the information from news, Verge claimed that around 250,000 XVG were stolen by the rogue miner, but dissenters have claimed that as many as 3.9 million coins may have been taken.

As of now, the price of Verge feel down 14,57% and continues to decrease. The market capitalization of the coin dropped from $1 billion to $845 million just in 24 hours.

Bear Market to Hit Mining Hard

BitMEX research division presented an analysis of the impact of market decline on the mining industry

The cryptocurrency market has experienced a marked decline over the past weeks. The BitMEX research division presented an analysis of the impact of these events on the mining industry. Bitcoin hash rate has fallen by 31% since the beginning of November, which is equivalent to the capacity of 1.3 million Bitmain S9 devices. From this, BitMEX concludes that miners as a class are in a difficult situation, however, they may have different conditions, and those who pay more for electricity, are forced to turn off their equipment first, while others may still be quite viable.

The decrease in the price of Bitcoin by 45% since the beginning of November has already caused two recalculations of the complexity of mining to the lower side - by 7.4% and 15.1% on November 16 and December 3, respectively. The first recalculation turned out to be the largest since January 2013, the second - since October 2011.

Bitcoin mining revenue fell from $ 13 million per day in early November to $ 6 million per day in early December. The fall in the size of the miner's encouragement turned out to be even more rapid than the fall in the price of cryptocurrency. This is due to the delay in recalculating the complexity of mining. For the six-day period ending December 3, 21.8% fewer blocks were mined than expected, since the miners left the network before recalculating the difficulty. As a result, in addition to reducing the size of the miners' encouragement in dollar terms, due to lower asset prices, they received 21.8% less bitcoin awards.

One of the popular reasons for the recent decline in the cryptocurrency market is that miners sold bitcoins to cover their costs of hash warsin the Bitcoin Cash network. The monitoring platform Boltzmann recorded an unusually large sale of Bitcoin by the miner on November 12, that is, 3 days before the hard fork of Bitcoin Cash.

BitMEX assumes that the actions of miners over the past weeks could have played a significant role in reducing the market, however, recommends not overestimating their value and reminds that in a bearish trend, prices continue to fall regardless of asset movements and news.
