PS : I mined for 1 year with 5 Aorus 1080ti's, and yeah, I sold at 900 piece, cause those 20$ day with 5 TI's is just.. boring

Each his vision of the ROI thing

Now, I make 200$ per day with approx same invest (4500$), and you know how you said it before.
Yes, a little more risky, but uncomparable, and I succeed in that since 2 month.
2 months at 6000$ each month..
Good luck mining

Others invest 5K and get 1M in returns, selling drugs, for example, but I don't see them around fucking around with Ti's so maybe you can try and chat at EliteSmartInvestorstalk.org
