Hi Guys,
What's the best BitCoin miner these days? I live in California, so electricity isn't cheap.
I was thinking of getting this one because it's easy to acquire:
1. GekkoScience Compac USB Stick Bitcoin Miner 8gh/s+ (BM1384)
2. Bitmain AntMiner U3 Bitcoin Miner Version 2
Thoughts?
I wouldn't go for the U3. It's known to be unstable...
I'm running a GekkoScience Compac myself, and it's a really fun device. Do be carefull, it runs at a little over 10Ghs/s at my place, so it's not the same as an S7, witch gives you almost 5 Th/s.
With this, i mean that with a stickminer, you'll only mine a couple thousand satoshi's a day... If you buy an S7, you can actually make some real coins

If your doing it for fun you could use either. But keep in mind you will not make back what those cost. They are considered "lotto" devices to most as they can use them for little electricity trying to hit a block. It will not make what you pay if you try to just mine it. Also keep in mind chances of getting a block are slim.
But the compac is the easier one of the two without messing around with zombies. But the price of U3 keeps it in peoples eye. I personally use both for fun, but I use a RPI for compac controller and crazyguy's custom firmware R1 for the U3's to get rid of zombie problem.
