Hey. mining has become quite unprofitable for a long time. if anyone can prove otherwise to me, I'd love to have a precious experience.
2013 KNC 550gh Jupiter Miner BTC miner. (ROI'd in 3 weeks)
2014-1st half of 2015...nothing available of any note as NEW equipment...bought only used till July 2015...(see below)
2015 got SIX KNC Liquidation 5 cube (new) 400mh units for $1,900.00 and (1) KNC 4 cube (new) 300mh unit for $1,800 on Ebay Corp Dump. Total of 7 new units.
Starting, April 1st, 2016 got (
Bitmain units, four L3's at 250mh and four L3+ units at 500mh by July...during the $4.15 to $50 pump. Got (4) more L3+'s last arrived in Sept.
All units EXCEPT the 2013 Jupiter are still earning PROFITS and All my units, EVER, have ROI'd.
I have not found ANYTHING since (September 2016) worth swapping crypto for ASIC equipment..so you may have a point.
So yeah, it is rare, 2016 was the exception for scrypt-pow machines...I have KNC Titans that have been running 24/7 since Nov 8th 2014...still profitable...
...and I may have another couple years, after this, only chasing down USED ASIC equipment...but as you see above...mining can make you $$$ if lucky!
