I think i need at least 1 more TH than my current 5.2TH. I think 6TH is the standard for solo miners like me to try their luck at home. I hope to be able to add more to meet that standard. thank you for your comment sir

surprisingly, after 5 months running nonstop, my best difficult increase from 0 GH/s to 1.8 GH/s (after 3 months) and now break to 3.2 GH/s. still on hope for a miracle! with #bitaxe
