It means: Without using a system that sucks the air, a use of air-con is useless in trying to cool the rigs. I thought the aircon will also get rid of the hot air from the GPU?
Not totally by itself (for significant improvement). There's still the need for another fan to blow the air into the GPU's (will explain everything below). Any experts know if he right or wrong?
He's kinda little bit of both, since a simple air flow does the trick. Also is this true? As probably all have and will say - AC is useless for this purpose
Need air movement
Fresh (cool) air should be drawn in to your mining room and stale (hot) air should be sucked out
This principle can be displayed by opening a window/door on either side of your house and let the wind do the work (depends if your location is windy enough).
If there is a huge amount of heat being generated then add large fans to enact the above
Found here https://bitcointalk.org/index.php?topic=1834513.0Yes, it's true but take note that a large fan isn't needed if you'll be using 1 or 2 GPU's only (a single small to medium fan does the trick, even if it's a cheap one with weak intensity).
From my own mining experience (as of late): Intensity of 23 GPU with it's own fans alone = at 75% fan speed is at 75°c GPU with it's own fans + air-con= at 70% fan speed is at 72°c GPU with it's own fans + air-con + an excess fan that directs the cool air into the GPU and pushes it away from GPU = at 65% fan speed is at 61°c-65°c
Some notes: 1. Not all GPU's are the same and it could affect the way you could improve the heat issues a. Different types of fans (not sure if a blower type of GPU can have a further improvement with an excess fan since never had one, although I'll be getting one by tomorrow and will try to update this post in the coming days) b. Direction of the airflow in each GPU is different c. The type of casing for the GPU's matter as well (open type, close type) 2. As much as possible, don't go beyond 75% fan speed and 75°c (I've seen some go beyond it but wouldn't recommend it since the GPU and it's own fans life, reduces significantly). |

i have stopped using elctrum atm, fee too high and if low fee unconfirmed for a long time
That has nothing to do with electrum, it's how fees are at the moment. You can use another wallet and end up with similar results (delay in confirmations, when a low fee is being used).
Appropriate fees (an estimate): http://bitcoinfees.21.co/#fees |

I have an old Android phone which I want to use to test mining any of the coins which is easily mined by phone. Any help for me.
Go to the following website (link to the android app is in the bottom area): https://minergate.com/Direct link: https://play.google.com/store/apps/details?id=com.minergate.minerI have a laptop though but I heard it could break the system that is why I don't want to try mining on my laptop.
Take note: You should expect a damage to the phone a lot sooner than a laptop. From my personal experience in the past, it took my phone 5 minutes of mining to get hot (really hot), even on the slightest intensity (you can choose the intensity from the app itself). My advice is to forget it. |

anyone have a recommended list of trusted coin exchanges? I'm looking for something that maybe has both pc and app friendly versions?
1. https://shapeshift.io/ (Has mobile versions) 2. https://changelly.com/ (Doesn't have a mobile version and there's been couple of complaints lately) also maybe a list of trusted multi wallets that I could use, or would r be better to just stick with the original coin wallets?
It would be best to use the original wallets of each coin instead, since in terms of safety, the multi-wallets aren't that safe. |

I'm newbie here,Are there any legit bitcoin mining company or basically most of them are just scam.
Most of them do actually turn out to be scammers (sooner or later) but so far, Hashnest has been somehow acceptable (although with a lot of issues, that you can read on their thread). Website: https://www.hashnest.com/?locale=enANN thread: https://bitcointalk.org/index.php?topic=766448.0
As much as possible, stay away from such websites and buy the mining rig instead (this way, you'll have full control over it [in case you've got a cheap electricity rate].) |

No need for any sort of payment since you can pretty much fix this yourself (although it's going to take couple of hours since you'll have to use a popular website that gets filled quite fast): https://www.viabtc.com/tools/txaccelerator/Your transactions are using funds from a chain of unconfirmed transactions (those should've received confirmations first, before both of the Tx ID's that you provided). If you get lucky enough to submit all of the transactions below to the accelerator website (ViaBTC), all of them can be included in the next block that they mine. Use the accelerator at first few seconds of the hour reset (UTC time), since there's a limit of 100 TX's/hour. Unconfirmed tree: 1. https://blockchain.info/tx/bbcaaf223d10e7ca05907bd2f8f48cf2e77b309a8ff33d9f611793c6f0531775 [Update: Got confirmation by BTC.com, I didn't do anything]2. https://blockchain.info/tx/6dba760df5e55d2424972c802b5ab9f3c0c8a01c573c583390f2f31f4ad75934 [Update: Got confirmation by BTC.com, I didn't do anything]

Will try to help you as well, but I'm a bit busy and might miss the tiny window for accelerating them. |

Yes, that's pretty normal (nowadays). Reasons: 1. Low fee being used 2. A transaction that uses funds from another unconfirmed transaction
Knowing the transaction ID would have helped, but one of the above reasons are mostly the case. Simply go to this thread for solutions: https://bitcointalk.org/index.php?topic=1802212.0 |

So after beening on vacation in a few south american countries making new friends thanks to bitcoin, i got a few propositions from a few people into
setting up a mining farm the biggest + to this the farm will get a 50% off what ever electricity cost would be.
Do you know the exact electricity rate (at 50% off)? Can give a better idea if it would be worth the trouble. My biggest question is should i fully setup for bitcoin or should i do 50/50 btc and an altcoin like ETH.
Knowing how much your exact budget is, it's quite important. If you happen to be a whale (a lot of funds), go with full BTCitcoin setup but if you happen to have only few thousand dollars, then go with full altcoin setup. Around 40k-50k, go with both at 50/50.
Take note: Every single person, thinks differently so my preferences might differ with others. Always do the calculations and go with the most estimated profitable option. |

You should've used ViaBTC on first few minutes (first few seconds at the moment) of hour resets (UTC format). In case you're willing to pay, you can also use ViaBTC's paid accelerator service (they charge 0.01BTC/transaction).

Unfortunately this transaction is using funds from a lot of unconfirmed transactions that goes back as below: Unconfirmed transaction tree: 1 A: https://blockchain.info/tx/99ab2e7e9eb697281866e70e277dded2033fe917e0a93283197af6d3eedb667a [Update: Accelerated, got confirmed by ViaBTC]1 B: https://blockchain.info/tx/0f0d41d09c4f036f5e1756ad6fd1201d32b03cc59b15a83b2eded3aa14e92288 [Update: Accelerated, got confirmed by ViaBTC]1. https://blockchain.info/tx/307f07dac977aaa959684b96f22f346dc406f344b857431e0a611dcb74d27800 [Update: Accelerated, got confirmed by ViaBTC]2. https://blockchain.info/tx/f3c2e8227e47a65497ded80bb77e47ac59cee9f7510b59af2e9513ed068b5304 [Update: Accelerated, got confirmed by ViaBTC]3. https://blockchain.info/tx/a681774b34b1b65cc3243a1baf4427db3fed872e788c74337d4a41c29e9296b2 [Update: Accelerated, got confirmed by ViaBTC]All of the above transactions should receive confirmations on that order first, then the intended transaction that you posted, can receive confirmations: https://blockchain.info/tx/fd8bec31a352981be118b2de9d1898fcf2be3c753b20f1393e3d2787b95b51d1 [Update: Accelerated, got confirmed by ViaBTC]
Furthermore: If you can contact a miner or someone that has access to choosing pool transactions, all of the above transactions can be included in a block (in exchange for certain amount): 1. macbook-air: https://bitcointalk.org/index.php?action=profile;u=161142.

The fee for the transaction is ~177 sat/b, which seems to me pretty fair.
Any ideas why is this happening? Any ways to accelerate this?
The fee is actually on the low side and that's the main reason. If you check the following website: http://bitcoinfees.21.co/#fees it says: The fastest and cheapest transaction fee is currently 390 satoshis/byte, shown in green at the top. There's a lot of unconfirmed transactions at the moment and fees have increased significantly. You can you "ViaBTC Transaction Accelerator Tool": https://www.viabtc.com/tools/txaccelerator/Use it on first few minutes of the hour reset (UTC format). Take note: They also have "paid accelerator service" which costs 0.01 BTC/transaction.

Saves yourself from the hassle and just buy crypto instead (at the same time, your money is completely in your control). Most websites that offer mining contracts (there's few that so far are good but I won't list them), turn out to be scam websites (along the road) and you'll end up on the losing side (stay away from such websites).

I am working on a project that processes bitcointalk's thread, collects data such as posts, members who posted them, their activity, trust etc and then assigns a score to everything, then does sentiment analysis on the post content and tells if the thread is in positive condition or in a bad condition.
The primary objective is to measure the future of altcoins depending on their threads as their threads are the place where the real stuff appears. Currently, I am in the data collection phase.
Has anyone does this before? What do you think about it? How were the results? Looking for productive feedback.
For the majority of the first part (bold texts), yes (achow101 has done it), although it's more in general: https://www.bctalkaccountpricer.info/Ann thread: https://bitcointalk.org/index.php?topic=1142314.0
For the second part, that's something new but there's one issue. In altcoin threads (most of them), there's a huge number of shill accounts that try to make a coin look better and more valuable than they actually are. What process you'll be using to eliminate such conditions for the analysis part? |

Is my fee appropriately high enough or how do I read the recommend fee chart?
No, your fee is actually pretty low. This is what you should've used (if you make a transaction now, not sure what was the recommended fee 19 hrs ago): The fastest and cheapest transaction fee is currently 360 satoshis/byte, shown in green at the top. And you used only: Fee per byte 134.048 sat/B There's a big difference, and it's going to take a long time (normally) for such transaction to receive a confirmation. According to the chart, that falls in the 0.0000012-0.0000015 btc/byte and the current estimates is 50 minutes.
Just checked and it's 40-Inf, meaning 40 minutes to infinite time (just so you get the picture).
Luckily there's a service called "ViaBTC Transaction Accelerator" that you can submit you're transaction there (as long as there's the minimum fee of 0.0001BTC/KB), and they include your transaction, on the next block that they mine: https://www.viabtc.com/tools/txaccelerator/Take note: There's a 100 Tx's per hour limit, so use it on hour resets (UTC format). |

Although your Tx fee was too low (mentioned by hexafraction), it was good enough for the ViaBTC accelerator to accept it and I was able to submit it successfully (you can expect a confirmation, whenever they mine the next block).
Always check this thread: https://bitcointalk.org/index.php?topic=1802212.0
To keep up with blocks being found (look for ViaBTC, same as default forum time): https://blockchain.info/blocksUpdate:It just got it's first confirmation. |

blockchain transaction pending since 4 days? What to do? help!
Read this sticky thread: https://bitcointalk.org/index.php?topic=1914800.0Update:0.00560754 BTC , tax 0.0002712 BTC ??
Not sure what you're asking, but if you mean the transaction fee is enough for the small amount, then the small amount you sent doesn't matter, the transaction size it does (fee depends on that). Please post the transaction ID, in case you're lost at what step you should take (it would be easier for us to help you). |
