absolutely, why is anyone even discussing anything with less than 1TH at this point. Its a waste time and energy. What could you possibly mine, maybe 10 sats a day? The popular USB miner out there that currently does something like 300GH is a complete ripoff. People need to realize that, and stop promoting it
But there are many home miners, like myself, who are open to the idea of a lower hash rate... 3, 5, 10TH machines. Especially if they are on the quieter side, and do not pull massive amounts of power.
Simply because some people want a small ASIC that runs with
almost no power consumption and no noise, as a lottery ticket for solo mining. Others are just interested in these ASICs as a hobby, or others use them to demystify mining without risking much.
No interest? Tell that to the guy who found a block with a Gekko Compac F not so long ago. Do you think people would bother to develop such ASICs and others to use them if there was no interest?
Just because you don't understand the point of something, doesn't mean there isn't one. Many people like to have a chance of finding a block (even if that chance is tiny) at the cost of just a few dozen watts.
