Input: Consider Input: Rhetoric between President Donald Trump and North Korean leader Kim Jong Un has escalated. In response  North Korea’s foreign minister reportedly said the nation may set off the “most powerful” hydrogen bomb detonation in the Pacific. No other details were provided  but at face value  such a blast would be 1 000 times as powerful as the Hiroshima bombing. Atmospheric testing of nuclear weapons can lead to multiple dangerous scenarios.
Ri Yong Ho  the foreign minister of the isolated nation  reportedly told journalists that North Korean leader Kim Jong Un is considering such a test blast.
“It could be the most powerful detonation of an H-bomb in the Pacific ” Yong Ho told reporters at the United Nations in New York on Thursday  according to a story by South Korea’s Yonhap News Agency. “We have no idea about what actions could be taken as it will be ordered by leader Kim Jong Un.”

The suggestion came in response to bellicose rhetoric exchanged between US President Donald Trump and  Jong Un .
In a speech before the United Nations General Assembly on Tuesday  Trump called  Jong Un  a suicidal “rocket man” and threatened to “totally destroy” North Korea if the US is “forced to defend itself or its allies.”  Jong Un  allegedly responded with a written statement  in which he called Trump a “mentally deranged US dotard” and said that “a frightened dog barks louder.”
“Trump is basically creating audience costs for  Kim  to back down ” Jeffrey Lewis  director of the East Asia Nonproliferation Program at the Middlebury Institute of International Studies at Monterey  told Vox. “If you dare  Kim   it creates pressure for  him  to respond with  his  own provocation.”
“The stakes and heat in this conflict have not been this high since the Korean War ” Tristan Webb  a senior analyst for NK News  said in a story published by the outlet on Friday. “Kim Jong Un said in July that the … showdown was entering its final phase. He appears psychologically prepared for conflict.”

All are wanted by Madrid for actions related to the push for the regionâs secession from Spain.  Puigdemont  has become the public face of that move for independence.
 Puigdemont  traveled to Belgium shortly after Madrid took control. On Sunday morning   Puigdemont  and four of his former councillors presented themselves to police in Brussels.

Input: Consider Input: The Nvidia GeForce GTX 1080  Ti  (1080 Ti for short) is one of the best GPUs on the market right now for PC gaming  but the units are becoming harder to find as retailers can't keep up with the increased demand brought on by cryptocurrency miners. Many 1080 Ti models are regularly out of stock through online retailers  or are getting marked up to higher and higher prices.
The 1080  Ti  typically goes for around $1 000 or less  and  it  used to be pretty easy to find online. Now popular retailers like Newegg that sell the GPUs list dozens of models as "out of stock " while other online marketplaces like Amazon or eBay have prices marked up by hundreds or sometimes even thousands of dollars.
What makes  the 1080 Ti  so appealing to both gamers and cryptocurrency miners is its 11 GB of GDDR5X memory running at 11 GBps  which means it can handle a lot of processes very quickly. For gamers  this means high-quality imaging and high frames per second. For miners  this means a faster rate of mining.
For gamers who are looking to upgrade their PCs to play hardware-demanding games or make their games look better  the shortage means 1080  Ti  is a less-desirable GPU. Why wait or pay up for one when you can get a slightly lower quality GPU for less money and hassle?
Unfortunately  other GPUs close in capabilities to the 1080 Ti â like the 1070 Ti or Radeon RX 580 â are experiencing similar shortages and markups (although not quite to the same degree). RX 580 GPUs are also being sold in bundles specifically for mining  and no gamer would need four or more GPUs to play even the most demanding games.
This shortage probably isn't forever  though. If the cryptocurrency bubble ever bursts  the hype will probably die down and everything will go back to normal. Plus  whatever the next generation of GPUs is will make 1080  Ti  cards much easier to find and buy.


Output: The cryptocurrency craze is causing a shortage that gamers aren't going to like
