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

High-end graphics processing units (GPUs) were already expensive. But now that they're being used to mine cryptocurrencies like Bitcoin, costs are getting ridiculous.

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.
