It may be possible to profitably mine Bitcoin using ASICs if you time it right, however you have to ask: why would mining hardware companies sell machines that can literally print money when they could run them themselves?

Hardware manufacturers are likely well aware they're dumping more hardware on the market than Bitcoin can profitably absorb. They're enabled by customers willing to preorder hardware months in advance who are essentially gambling that the mining difficulty won't rise too quickly to make their brand new hardware unprofitable.
