I got into mining about a year and a half ago. Started with one Block Erupter and several USB Antminers. Just Bitcoin and Namecoin, trying out several different pools (BitMinter, Eligius, Slush).
Then I discovered UNO on Bastille Day (July 14th), 2014, and started looking into it. I ended up getting a bunch of more USB Antminers (each 2+GH/s), 2 IceFury/NanoFuries (~2.5 GH/s), then 6 BiFurys (~5 GH/s each, except for one defective one that ran at about the level of a NanoFury).
I was mining UNO exclusively by now, using MultiMiner, and various pools, moving from one to the other. Here is what my rig(s) looked like:
Note: the 2 NanoFuries are sort of hidden behind the fan on the little Amazon USB hub on the right, you can sort of see one of them. Also, the Block Erupter is visible at the back of that same hub.
Total was about 70-80 GH/s. Interesting, but USB ASICs are, to be frank, a PITA. They've got to be attached to a running PC which has to be on all the time, or at least all the time you want to mine.
I was also buying UNO, here there and when I could.
Then I bought 2 AntMiner S3's. Now we're talking serious hash power, at least compared to the Frankenstein USB rig setup. Each S3 was ~440 GH/s. And they ran *stand-alone*, so even when I was traveling or had my laptop off for whatever reason, they still mined.
Combined with my USB rigs, I was often getting about 1 TH/s. Not bad. At the time.
Then I bought a 2 TH/s contract with Genesis Mining. At first, I wasn't at all impressed with them. OK, just not impressive.
Fast forward to today. I retired the USB ASICs (a friend of mine is going to help me try and sell them -- either piecemeal or the entire rig -- on eBay). So I'm just left with the 2 S3's, returning me an average of 850 - 900 GH/s (just under a TH). With mmpool, I get a teeny sprinkling of Namecoin, UNO, and Bitcoin. And I *mean* a sprinkling, every 3-5 days!
Genesis Mining, on the other hand, has somehow upped its return so that I'm usually getting .9+ UNOs *every single day*!!!
So I'll be selling the S3's too. Tired of the noise, the electricity costs, worrying about hardware, pool downtimes (with and without DDOS), occasional internet connection problems, etc., etc.
Bottom line, Genesis Mining is pretty darn cool (and I don't even follow their thread here on BCT). Whatever they're doing, they're doing right. Getting almost one UNO a day in these post-halving days with 2 TH/s is fine by me!
And I can dump the hardware and the hassles...
I'll be curious as to what GM can do come the next halving...
Anyway, in the meantime, a BIG THUMBS UP to Genesis Mining!!!
