US-based chipmaker Nvidia will reportedly pay $5.5 million to settle charges that it unlawfully obscured how many of its graphics cards were sold to cryptocurrency miners. The US Securities and Exchange Commission (SEC) announced the charges and a settlement with the company. Its order claims Nvidia misled investors by reporting a huge boost in revenue related to "gaming", hiding how much its success relied on the far more volatile crypto market, reports The Verge. Nvidia is not admitting to wrongdoing as part of the settlement, but it agrees to stop any unlawful failures to disclose information. The charges stem from Nvidia's fiscal year 2018 financial reports. The SEC noted Nvidia saw an explosion in crypto mining-related sales in 2017, when the rewards of mining Ethereum grew dramatically. Crypto mining was widely reported as a cause of GPU scarcity, and Nvidia launched a separate CMP line specifically for mining, attempting to prevent shortages for gamers. But employees apparently acknowledged that many gaming GPUs were still going to miners. "The company's sales personnel, in particular in China, reported what they believed to be significant increases in demand for Gaming GPUs as a result of crypto mining," the order said.
