recently, especially on Aliexpress, miners for sha256 are being sold, therefore for btc for just over a hundred euros..
they are called lucky miners and are from 400 to 500G.(8 years of computing power=......


considering the current difficulty of btc and the miners in circulation now, these are absolutely USELESS.  LUCKY precisely because being lucky enough to discover a block with this computing power is like winning the lottery... forget it... wasted money and as always... let's make the Chinese rich...

it consumes little and can only be used to play and try to configure a miner and watch it work. nothing more. nerdy stuff and that's it.
