If you have a high budget you can get yourself‘s Antminers which will cost 1000$ +. You can calculate the profitability using .
ASIC mining has gone industrial. Corporations are building mining centers in regions with very cheap power, and filling them with millions of USD worth of ASIC miners. Greater mining power in one hand does have some slight advantages which adds to their more efficient processes.
Finally, ASIC miners have been catching up quickly technologywise: Every few months new chips get announced moving the scale down a few more nm. Currently, we are reaching 16nm technology (Oct 2016), which is already pretty close to the general state of the art. The problem with that is that every step of miniaturization comes with a leap in power efficiency, quickly obsoleting older generations of ASICs. Chances are that your investment will outdate before it pays for itself – even when you are just looking at cost of acquisition and have no cost of power.
