hello fellow miners, How's the pick today?, everything good?

I'm mining for 4 days, I use windows 10 with 1 video card zotac 1080 AMP! Extreme and Bminer to mine, EWBF got 500 ~ 530Sol/s and with Bminer I got 590 ~ 605Sol/s for this reason I'm using Bminer as a Miner.

Ok, the question is: starting now, with no budget to buy another board, mining with this board, I would have a new board value only after one year and two months (if it did not burn before)
in short, it does not pay to spend the life of the video card + energy and pray to have a profit to buy an additional video card (my opinion)

Anyone have any tips for beginners?

here a video card like zotac 1080ti costs (BRL)R$4000 ~ 5000 (US $1238.39 ~ 1547.99)

my mining estimate per month is (US)$70 (BRL R$ 226.10)

I'm sad =(

Excuse my poor english =)
