With the value of cryptocurrencies like Bitcoin hitting all-time highs amidst the global crisis, crypto miners are hoarding high-end graphics cards to build their mining rigs. So, if you are struggling to get your hands on Nvidia’s latest RTX 3080 series cards, it is because this guy from Las Vegas bought 78 of them to build his dedicated rig for mining cryptocurrencies.

However, an investment that huge does not seem to be an issue for Byrne as he reported that he got the return on his initial capital after only two months of mining. Moreover, apart from the additional cost of electricity and maintenance of the rig, the man says that he is earning almost $900 (~Rs. 66,000) a day, which means $27,000 (~Rs. 19,79,910) a month.
