That's a lot of money for a 4-5 year old company. I wonder what their plan is for when the viability of mining decreases too much. Will they just close down the business or will they move onto other cryptocurrencies? I guess at some point mining will no longer be done - only a few coins will come out of this as solid, usable projects.
I think some fresh competition would be a good thing for the market. Though I have no idea how hard it is to enter the mining hardware manufacture segment at a state where the new company could also be a decent enough disruptor. It's already costly enough to buy graphics card because of cryptocurrency mining popularity and no one seems to be doing anything about that.
