Congrats to them! I hope every bitcoin exchange around the world doubles their previous all time highs soon! It should happen fairly soon with the way bitcoin has been moving lately.
Its not that good. BTC exchange is taxed like 30%, so its not even worth for my Brazilian friend to sell the BTC to FIAT. He has to spend it. But he still get raped on import tax which is completely ludicrous. So cool we all got a price increase, but the Brazilians are still boned... Do the lucky ones who live near a border with another more Bitcoin friendly country make trips there to buy Bitcoins, then smuggle them back to Brazil and sell them for VAT free fiat profit? Is bringing Bitcoins without declaring them classed as smuggling in Brazil, and are you supposed to pay tax on face to face sales? Well you don,t really "move Bitcoin into Brazil" so its all nonsense anyways. The problem is its very hard to buy bitcoin this way since its not something you physically buy. You still need to use your Brazilian credit card, unless you move to another country, open a bank account etc, which you typically can't do without being long into the emigration process. |

Mining is profitable again for some old hardware.
no, it is not except some chinese mega farms next to power plants:) at least in whole Europe, I really can't imagine a place, where mining is profitable.. Sorry to hear Europe has crazy electricity price. Here in Québec we have hydro and its a few cents per kWh. And in the US there are a few profitable places too. China, Venezuella. There are a lot of places where it is cheap. And it is very profitable here. So good thing to keep in mind if YOU want to profit. Buy miners and send it to hosting services in Québec, or China, etc. |

In short, i have a S5 that i got half working (got it cheap), then second blade is dead and the FAN2 has no reading
I could put a new working blade in the controller, but would such history warrant against doing this? It seem like the controller is not working as well as it should, i'm just wondering if doing this could damage the new blade?

I got the miner from bitcoinware and hasn't work since day one. I noticed one of the screws holding the heat sink didn't have a spring behind it.
I've had issues with Bitcoinware, check my feedback sent if you want. Anyways, after 1 month of bad communication on their part, the issue was resolved, but you really got to hold your end of the stick. You can try fixing it but when its DOA... The problem is for returns they wanted me to do it at my costs, so. Lost of mining time, extra expenditure AND their miners are overpriced as f**k. So yeah. Return, cut your losses and get your stuff somewhere else. |

Mining at home is very profitable, just with ASIC, if you don't have exorbitant electricity price compared to the world, Bitcoin is *very* profitable, with the Bitcoin being at a high price. Even though its been going down, now. |

Well by then miners will earn based on transaction fees but it will still good enough for miners to keep the blockchain work because at that time bitcoin will have already gone through many halvings and the fee will have gone up high enough to keep miners pointing their hashes to it
Correct, the previous comment stating it will not be possible to mine anymore is completely wrong. This will be progressive anyways, so the blow will be much lower than our current halving, since when the block reward drop to 0, it will have been very tiny for a very long time. If the mining fee is too low, this just mean many people will drop out and the others will resume mining profitably. |

You need 1 Bitcoin.
I don't think it's enough unless bitcoin price will pump out to $1M each (which I highly doubt will happen) Holding btc?¿
or
trading btc?
Holding=100
Trading= 20
Dude I can't understand your post  Would you mind elaborate more what you are trying to say? maybe he means that if you keep trading with bitcoin for 20 years and start with 20 bitcoins youd end up with a 100coins? He means if you do this now. You either need to buy 100 BTC and let it collect dust for a long time. Or buy 20BTC now and keep rolling it to make 100+ BTC. I'm not sure what a sure fire way of growing 20BTC into 100BTC with trading, but its not too hard to do through other methods, since 20 years is kind of a very long time. |

i think 6 confirmations is enough to get sure about transactions that is 1BTC+.
On other hand 3 confirmations is enough for lower amount of BTCs.
Yes these are the best way of getting your bitcoin transaction most securely. But 6confirmation or 3 confirmations are best suited only with latest bitcoin core client only. If you use old bitcoin-qt client then you must wait for some 30 confirmations. This applies to SPV clients too. They trust the miners without verifying the validity of the blocks. When pools are SPV mining, they don't check the validity of the block and whether it complies with the network. Those mining pools then generate invalid blocks which get invalidated by Bitcoin core 0.10+ but not anything below or on 0.9.4 or earlier as those Core clients are not aware of the new rules. AFAIK, this isn't a threat right now. Majority of pools are mining on correct rules and creating valid blocks. Which also mean it does not mean if some wallets are outdated and accept some invalid blocks, the network itself will reject it, because most hashrate is pointed at the right wallet version. Still too bad but not a threat. |

Hey, guys i've just start mining bitcoin with guiminer and have a mhash/s of 350 first question is it good 350 or not and second question i am using mining.bitcoin.cz for mining bitcoin and im actually at 340 block accepted and no reward is it normal or is there a bug??? pls help thanks.
You can't mine Bitcoin with GPU or CPU anymore. You need to get ASIC. Depending on your electricity rate, which i invite you to tell me/us. We may be able to recommend you something to start earning Bitcoin, if you have a budget. |

Alright I'm already on Smit's I think I've already read your guide but was scared too screw with the voltage!
I'm in Sydney and humid my S4 is currently has one board at 70 degrees will underclocking lower the temp?
How do you maintain the same hash rate even though it's underclocked?
It will help with the temp, however slightly. You could also do an underclock. And i think you mean maintain the same hashrate even though its underVOLTED? In that case, just lower the voltage drastically and try to run it at Freq 200, see if chips drop. You could try 0670. There is not really a danger if you go downward. Then you can overclock to 206 etc, and slowly raise the voltage to find what is stable. But if you have the stock PSU i do not recommend going to a full 212 or above. |

Well from what I've read plugging in a pcie 6+2 connector into the cpu slot (on the psu) will fry whatever your connecting.
You would have to verify the pinout. If you change the wiring so that +12v go to +12v and ground to ground, there should not be any problem, assuming the cpu socket is on the main rail. Seem risk prone. I think the best way to save a socket would probably use perif to molex, then use a 2x molex to PCI-e adapter to power the controller. I would not do this to power a blade.So the pci connection on top of the S7 is purely for powering the control board? I'm thinking of running each S7 off an EVGA 1600, but I need another port on the PSU for the controller. The EVGA 1600 should have enough cable on its own for 10 ports. With the 6+2 and 6 pci-e connector it comes with combined, this should not me a problem. If you mean because there are only 9 * 8 pins socket, there are two other things you can do; Use a cable with 2 6 Pins, or use a 6 to 6 pin cable and use the perif socket to power the controller. Lastly, the EVGA 1600 is probably a good pick if you want to OC it. But i guess 2x 750-850 G2/GS would be cheaper if you fancy running multiple PSU per miner. |

Hi all, Just made an account here.
Looking forward to learn more about crypto here.
As my name suggests, I do designing.
from everything forum related to professional business branding and 2D animations.
Maybe If people are interested I can setup a shop here. I wonder though
I have been using BTC for a while now
and wanted to grow my knowledge.
Until today all I ever did was get BTC as payment for designs and convert it to paypal on forum boards.
I gambled today and made $125, not much but enough for starter i guess.
I'd like to know more about blocks and what are those and other things I only heard about
excited to unveil the information about crypto here.
Thanks and Regards
graphicx
Feel free to ask questions here, i will try to answer them. Meanwhile, you could offer your services in the service section. However keep in mind you will meet much distrust at first. Such is the nature of internet and money. |

I doubt it will get down to ~200, but I just bet a fair bit that it's going to drop, I'd guess more likely back into the $230-$250 range probably before year end.
The price went up to 310$ before, 325$~ this time and went down to 220$ before, so probably 235$ this time. Its purely speculation but there are fair chances of the pattern repeating, until it get broken, which it hasn't yet. But profitability is still decent in the 240$~260$ range so works for me. People just now that thought cloud mining just became lucrative are probably going to get disappointed though. The BTC price is dropping now and the difficulty is going to make a big leap this time. |

I have a S5 with some history, the second blade was dead and the FAN2 from the controller reading does not work. I could put a new working blade in the controller, but would such history warrant against doing this?
Just wondering if the replacement board could get damaged because of the previous history, or if it work now, it'll be fine?

not sure why Dollar will be replaced by Bitcoins, not everyone goes online and believes in buying items online and lastly no Government will support it I guess since Government dont have control over Bitcoins
Actually... It could replace FIAT just fine. You would not have to go Online to buy item. You don't even have to go online to buy stuff right now... You can buy anything anywhere that accept a debit card already. And some Governments already support it and some Governments already oppose it. And Beside a global ban of Bitcoin, there is not much that can be done by then, unless they decide to bruteforce the whole network down, so... |

I would go for 21 BTC. In twenty years from now they could be a good sum. Also, 21 is a cool amount considering the total amount of BTC which will be 21millions.  Nono. 21 is a nice half of 42. But the good amount is obviously 42 bitcoin. And 42 bitcoins in 20 years with bitcoin at >20k give you possibly one million USD~ worth which by all mean would mean a good retirement cushion.  It all depend on if BTC manage to start competing with FIAT. If it does, we win. |

You can't be 100% certain of a Bitcoin tx until a "checkpoint" has been published (which unfortunately is a centralised thing controlled by the devs).
A blockchain "re-org" (where a better chain replaces the current one) can actually go as far back as the last checkpoint (which could be thousands of blocks).
It is extremely unlikely that such a "re-org" could happen (and has never happened so far) but re-orgs of more than 3 blocks have occurred before (the worst such problem was around 6 blocks from memory).
So you basically have to decide upon the risk you want to take in accordance to the amount you are risking.
This is why 6 blocks is rock solid. Even 1 block is relatively secure since the odds of anything being redone is low, and also why 3 blocks is standard. Waiting for 6 block is the sweet spot where it does not take *too* long but it is very safe. Although at this point i am not sure what kind of event that could invalidate 6 blocks old transaction. |

I meant $50/per month in Canadian funds not US.
Didn't realise you were talking about US Funds.
Our exchange rate sucks now if you want to purchase goods so I understand why you don't want to pay $140 USD = $184 Cad for an S3.
Ahh, that solve the mystery. Well in case there is any other confusion on my offer; I am talking about 100USD shipped, which mean of course i would consider 140CAD shipped. I have added this note to OP to make sure no seller get put off by the ambiguity. Canada/Québec is merely where the item must be shipped to. In Quebec do most homes there use natural gas for heating or is it electric? In Alberta pretty much almost all homes have natural gas, and when its -30C an electric heater is a huge waste of electricty hence most people here dont use miners to heat their homes only natural gas. In the East it might be different, so maybe that's why you are having trouble finding miners locally since its almost Winter. I'd say electric but its still somewhat contested. The electricity is very cheap here however so thats a plus. Not many seem to realize ASIC heating is THE best hands down. I offered it to a friend and i was looked at like i was weird. Anyways, Its not the winter, its the BTC price. It was very easy to get 2 weeks ago. Now suddenly people ask 1.5-2x for the same miners. I'll just sleep on it and hopefully someone come up with a good offer for S3/S4 or S5. Yeah don't buy that Antminer S3 for $140 CAD, you will regret it. Well, good thing i sold my BTC when i felt it was plateau-ing, now it is going to drop for a while, not sure how far before eventually rising again. This means i'm still interested in buying Antminer S3's and all the others, though its hard to put a hard/fix price on the miners. If anyone has from S3 to S5+ for sale, please contact me if you are willing to ship to Canada. Thanks! |

for the 1st contest, the "stock stick" run with only air cooling, can we replace the thermal compound?
same heatsink and air cooling 24 hour run without crashes if you want to use a different paste/compound I would think thats okay. What frequency are you attempting to run at? My two sticks run side by side at 225 Mhz with a temperature reading of 122F according to Minera (and who knows what that's measuring), and less than 100F at the base of the usb connector or anywhere else when measured with my cheap laser/ir gun (which I believe to be quite accurate). I just mention because heat is not my problem at all. They dont have a temp sensor so i'm guessing the Minera reading you're taking is from the RasPi's its running on? Unless you're somehow running it on some other device. |
