I bought stock in that company a few years back.. lol. Shortly after the price of BTC crashed and so did the stock. Im currently underwater with the stock but I think the idea of buying miners and reinvesting that money in more miners on a massive scale may pay off one day.
Heres their Youtube channel they talk about how they are doing there.

Its the only publicly traded crypto mining company I know of.. It is funny the same name was chosen as an existing blockchain company.
