Hello! I'm new to Bitcoin mining in general, and I followed a tutorial on how to get started. They suggested this pool. I just wanna say that I don't know like anything about bitcoin, besides the basics, and I'd like to know if I should go any further with what I am doing. I have an ATI (or AMD) Radeon HD 7770 (GHz Edition) that I use for gaming and, well, this. I get 200 Mhash/s, and I wanna know if this is good for mining. I've mined about 0.00000494 BTC so far, and that's within a day. I also want to know if I should upgrade to a better Graphics Card or an ASIC thingy later on. I know this thing is good for beginner users, and I just hope it survives everything I throw at it. Anyway, thank you  I like Bitcoin so far btw. I just wish there was a method I could take. (I only have like $50 to spend right now) You can hop on Amazon and buy one of these for $27 USD http://www.amazon.com/BITMAIN-ANTMINER-U2-Bitcoin-Overclockable/dp/B00ITD5NV6/ref=pd_sim_sbs_pc_1?ie=UTF8&refRID=1R9GF4V3NFV2KX7Z4RPC it will be around 10x as fast as your video card is and only use 2 watts. save yourself some money on your energy costs and save your graphics card. It will be a good intro to bitcoin mining. but its not going to make you rich. I started out with 3 of those and a Raspberry Pi and a USB powered hub and a USB Fan from Arctic. it was fun and enough to get me addicted hehe. |

haha an S1 for $50... imagine someone being that dumb... cuz you know you cant buy an upgrade kit for them to make them S3's... no really you cant just yet  maybe a Block eruptor Cube, those are only worth $50. s1's lil under $150 at x5 the hashing rate wow funniest thing on ebay is people selling corsair 500+'s with a cube for under $50... the power supply is that value! nice deals if you can snag it! |

I got a couple Antminer S1's for about $70 a pop after lots of bargain hunting. Amazing what you find when people misspell stuff. I used to find the usb block erupters for dirt cheap cause they would spell it block eruptOr. Search and you shall find. Also amazing what you can find on craigslist too got an Antminer S2 for $650 once. JT |

I was able to buy a single S1 + PSU for $110, as then two more for 0.065 each. @Billbags, it was probably found right after another block, so there were no new transactions to include. It happens once and awhile. |

So a block includes these 4 things:
1. A set of transactions
2. A timestamp
3. The 256-bit hash of the preceeding block
4. A nonce sufficient to make the hash of the block not exceed the current target
I now assume the transaction amount could be ZERO if that's the number needed in the control theorys feedback loop to ensure the proper amount of time a block needs to be completed to get 2016 blocks every 2 weeks.
Update: If someone could confirm or disprove this, it would be appreciated greatly. I can't find that transaction figures would deal with time in the block equations, so my theory on zero transactions may be false.
60minhr∗24hrday∗7dayweek 10minblock=2016 in 2weeks
Tcurrent=Tprior∗tprior/2weeks
D=work/2(32)=2(256)/(Tcurrent+1)∗2(32)
hashes/second≈D∗2(32)/600
Update:
To validate a block, a node checks several things including that the block’s hash does not exceed the current target, that the timestamp inside the block is not too far in the future or the past, and that all transactions inside the block are valid. So now I'm assuming zero transactions = no invalid transactions. This would make the node accept the block and cue it to be confirmed while transmitting it to the other nodes.
Last Update:
I had totally forgotten the fact that transactions happen everyday without fees, so I now realize that a block with no transaction FEES doesn't mean there wasn't any transactions and most importantly a block can be solved with zero transactions. Sorry for the madness, just trying to understand block #317553.Time to log off, relax and enjoy the pools good luck for awhile.

Correction. It had 1 transaction - the 25 BTC award. |

Why does the Bitcoin system allow for blocks with 0 transactions?

Why not? Bitcoin system is set to produce a block every ~10min with or without transactions in case there are none as it was in it's first days. The first transaction ever is in block 170 should we loose 169 blocks because there are no transactions? |

If you don't mind me asking, how much hashpower were you pointing at Slush's when you found that block? Also, congrats on finding the block! |

I had, and still running, 8 overclocked S1s for a total of 1.6 Th/s. One of the nice things about slush is that it lets you know and keeps track of blocks found by your miners in your user stats. I've never seen that at other pools. One of the bad things is when you lose internet service, like a lot of TW customers did this morning, your shares can shrivel away. I wish they would change that. I don't think pool hopping that big a deal. |

I agree and it's not just an unexpected loss of internet.
Taking one or more of your miners down for " maintenance" or " re-arranging " can and will cost you.
I dont know the ins and outs of pool hopping but I think regular users shouldn't be penalized.

lets say I have set miner to restart every 1 hour, does that mean the mined shares will be lost?

Just wondering why would you want to do that ? Bob |

Why would you reset them so much? Or at all for that matter. JT |

I have 28 different machine running various mining programs and never reset any of them.
I think your making a mistake.

my 2x antminers s3 batch6 seem to be running very unstable for me, when I first start them cold they run fine for many random amount of hours or days, and then suddenly losing 6-7% of power (from 440 Gh/s to 410 Gh/s), I have been experimenting alot, cleaning the heatsinks, running open/closed case, reversing both fans, keeping room they are in as cool as possible, but they seem to be doing that no matter what I try. restarting cgminer seems to be keeping AVG hash rate up.

Well I think you may be causing some of the problems your self. 1st thing you want to do is set the machine up and LET IT RUN for 24 hrs. These machines do vary in speed. Dont watch the present speed you want to watch the AVERAGE speed on the ANTMINERS. trying to react to every small variation can lead you down the wrong road. I have 6 S3's and they do vary in speed but after TIME they all average out. Take a step back and let your machine run for a while before you go chasing a problem that's not really there. Take it from someone who learned the hard way... Also machine speed on the GUI it not always reported as accurate at it could be. What is your " POOL" reporting ? |
