I bought 2 bobcat miners 300s for $500 a piece 2 years+ ago. After a 9 month wait they arrived and Ive had them both running nonstop from Orlando, FL and Brooklyn, NY respectively. Ive made $150 in HNT (only gotten this high with the recent market uptick) in that time. IMO mining helium is not a profitable and Ive been constantly optimizing my rigs trying to break even sooner than 5 years from now
