Aren't these still pulling profits? We pulled the listing as no demo's were sent. Wanted to how well they hash after a few buyers pulled out since we've never touched one and from reading here there a number of inconsistencies. Be nice to confirm.
At the actual bitcoin price, no, it's not
I got mine for 6k$ and I can make around 10$ per day (after electricity)
I have the Zig Z1+ and it's supposed to do 7.2 Gh/s, but in reality I'm only getting 6.6 Gh/s stable
The only way to get back the money from it is to continue mining until it's not profitable anymore at all and hope for bitcoin to moon then sell all the BTC accumulated
