I realize that miners will exist the entire life of bitcoin -- that's sort'a *defines* bitcoin's "aliveness."
Not sure what you mean by "a hashing chip in my car." Are you suggesting that electricity generated by burning gasoline is cheaper than the stuff i buy from my power co?
And sure, people will mine with whatever while it is profitable. Mining with GPUs is already *un*profitable, so even a free GPU is mining at a loss vs. energy costs, a million GPUs would compound that loss a million-fold -- DO NOT WANT.
Which part of my argument do you find flawed?
What do you think is going to happen to all of the current generation of technology when it is outpaced? Trash-bin?
If you ever visit NYC, don't be shy -- look inside one of those 40-yard dumpsters -- that's where the gear goes.
The point is power costs are not "essentially nothing," and hosting space does cost money, even if it happens to be your spare bedroom. If bitcoin value continues to rise, please don't assume that no new players will enter the ASIC field -- they most certainly will, with more efficient, cheaper chips. We're not at some ASIC terminus -- next gen is *already being developed*. Your chips will be in as much demand as 8088 cpus.
Mining bitcoin with GPUs is unprofitable.
Why would miners be added to other devices? I understand stuff like "let's add a clock to a radio, they both live on the nightstand," but a miner in a car? That's like adding a blender to a flush toilet -- why?
Why not?...its called a macerator ...... https://www.google.co.uk/#q=macerator&tbm=shop
