Is the fastest Bitcoin ASIC miner available today still profitable after block halving? As the title says, I was wondering if the fastest Bitcoin ASIC miner will be profitable after block halving?
The s7 miner is still a bit profitable (25% profit).
The s9 miner is the fastest and most efficiënt miner i know of and is way more proffitable of course.

edit/explaination:
Hashnest has a percentage monitor of profit/costs. Thats where the s7 number comes from. S9 is way more efficiënt following the specsheet on the antminer website. You can calc your profit over at coinwarz too, there you can edit power costs/usage and even the ROI is calculated there. Take a look i should say (its indication tho)
