Really impressed with all the pictures and i would like to hear what their expenses are and their returns so that it could inspire everyone to try out making these farms,till now i thought it was a big waste of time and energy to build one but i am amazed by how many have built a farm and still i am not convinced how much profit they are yielding with it.
I bought r9-270 cards back in litecoin's last pre-asic hurrah for ~$250ea and they have probably mined about $350/ea after electricity costs to this day, with frequent (or automatic) conversion to bitcoin (and/or withdrawn to pay bills), and still worth ~$100/ea making almost $1/day
I bought gtx1070 cards in september for LBRY at about $680cad each and mined almost $200/ea within the first month. by now, theyve probably made about $500/ea after power costs and at daily conversion. they are still worth $400/ea and mining $>2/day
I bought rx470 cards about 3 months ago at $300cad/ea, and probably made about $120/ea after power costs so far. the cards are still worth ~$220 and mining $1.50/day
between the rx470 and gtx1070 cards i put about $2500 into hardware over the last 6 months, and have returned ~$700. nicehash estimates my yearly profit at around $2400-3600 depending on the always-fluctuating altcoin markets. So over the 2-3yr lifespan it should make a healthy (50%+ profit) quite easily - and acts as a bit of a hobby. It can easily take a few days to setup, and an hour or two every week to deal with updates and fixing errors
oh, and the gtx1070 cards have SLI inside my gaming PC. so it makes for great gaming
Love it!!! I started with BTC way back in 2011 & had some cards left over & gave up on BTC mining a year ago!!!
My 7970 & 5870 & 2 6950's mined 3 times their value & I put some into 2 380's which in 3 months got me a 390 8gig & I made a good profit too.
Sold the 5870 & 6950's to help get the newer cards BTW.
