The longer story
The M50 is the previous MicroBT generation, now occupying the same value slot as the S19 family: efficient enough to matter on cheap power, cheap enough that the capital math forgives its age. Its durability record makes used units a more comfortable bet than most.
It suits budget-conscious miners with good power prices who prefer Whatsminer build quality on the secondhand market. On typical grid rates its era has passed — check the daily-cost column honestly before buying.
