I am seeing 333Mh/s SHA256 USB miners selling on Ebay for pretty decent prices ($25).
Why are buyers purchasing these devices? They don't appear to be profitable (.02 cents a day?) Am I missing something with these? It seems like difficulty of pretty much every coin passed these by a long time ago.
Is this a sign that the Cryptocurrency is reaching a larger audience and people are just buying a cheap ASICs to learn about it without the expactation of profit?
The main reason they sell is the simple one: There is a sucker born every minute. People sell them to people that don't know any better. Another reason people still buy them is it's like buying a lottery ticket. There is that one in a very huge number you will find a block and with solar power you can let them run forever. They are still usable on other coins and probably testnet but I'm sure s1-s5 are heavy on those coins now.
