i don't know but this is my personal deposit address(1Eh6Me7Kvq3sxVd7AVMBU1vJHtgiw2TYQe) from 6btb.com....I am sending from coins.ph and the other transactions are from different sites like freebitco.in, claimwith.me, claimers.io and send it directly to my personal deposit address...
Has the amount been credited by 6btb yet to your account there? |

That's right. I have a friend on Facebook from Venezuela and we talked reciently, he moved from all this haos to live abroad in Brazil and when I asked him about Bitcoin and crypto-currencies he answere that he has never heard about it before.
Obviously, the majority of the people there haven't likely head of Bitcoin. Main point of importance is that the people that do know Bitcoin, will slowly start spreading the word, but this is a process that takes a significant amount of time. Back in the days where Cyprus was going through a massive economical recession, people just assumed that the price increase was caused as result of that. Again, in that case the majority of the people there had likely no clue about what Bitcoin was. It wouldn't be the first time where crypto related news sites exaggerate the situation to draw more attention -- that's how they operate. Its obvious that this so called authors do sometimes exaggerate things or even blown out of proportion to sensationalized news to attract readers and click on them. I think Venezuela are really in deep economic problem, that bitcoin is the only means of survival for a few/many? of them. Majority may not have heard of it, but I think if the problems will continue then bitcoin will slowly gain awareness with its citizen that it can at least help them to buy food and groceries from other countries. It is really good to hear that a bad economic situation in a country is helping the people who are investing in bitcoin,i have heard that the electricity is cheap in Venezuela and there are many mining farms situated in that country and for them bitcoin will be a bonus to over come the struggle they are facing at the moment.
Yes, the electricity in Venezuela is quite cheap that's why they are mining in there. However, a few months ago, a mining farm was raided and all people involved throw in jail and the rigs confiscated. They said that this mining farms are operating illegally. This is the answer to the main question. Bitcoin will not be able to help residents of Venezuela because the government will not allow this. If people go into the bitcoin community, then the country's economy will never get out of the pit in which it is now located It should be a cautionary tale for people around the world - prepare for the storm while the sun is shining. Put some money in bitcoin/gold/somewhere off-shore when you can. When you see the authoritarians of any stripe - dictators, socialists, fascists, communists etc - headed your way, the storm clouds are on the horizon so protect some more of your wealth. And perhaps yourself and families by fleeing. Just ask more Cyprus recently and many other places. People think "it can't happen here" wherever "here" is, but it can and often does happen. Also protect yourself now from the authoritarian central bankers who will drain your wealth away a few (or more) percent per year through inflation. A few percent adds up over time. |

I have heard that the situation in Venezuela is too bad, people are running from the country and politic system which can't protect them. Crypto-currencies really give a hand of support to people who can't just stay everything and leave the country. I hope the situation will stabilize there soon, because of this thing that is going on there is just a nightmare.
It is the political system and the authoritarian leaders from whom they need protection! After almost two decades of a socialist dictatorship the end result is not surprising, but the siren song of trading freedom for "free stuff" worked again. Friends of mine there in 1998 and 1999 saw Chavez win and tried to get as much of their wealth (and their families) out of the country as possible. Unfortunately for the majority of people, Chavez et al duped them into voting for their own enslavement and they couldn't have left even if they wanted to. He and his cronies lived the high life while taking a country that had been prosperous in the 1950s and for several decades thereafter close to destruction. Bitcoin helps protect freedom by stopping a Chavez-type leader from destroying and/or seizing a country's currency, savings and investments. |

I can refer you to articles saying that using bitcoins in general is a bad idea because you don't know what you're doing and therefore you can easily loose your coins.
Obviously, if you don't know what you're doing you can easily loose your coins - it doesn't take a genius to figure that out.
If you do know what are you doing, at the other hand, and if you know what you want, brain wallet might be just the best way to go for you.
Which my and my friends' brain wallets have proven true for years.
So cut off the crap as I'm quite tired already listening to this dogmatic bullshit that you dare to call 'research'.
I have to agree here. Brain wallets are a bad idea if you don't know what you are doing. Some people know enough to create one and so can do it correctly. I wouldn't recommend it in general though - piotr and company seem to be exceptions Would it be best to just try and memorize your wallet mnemonic? Most likely, yes. And the dictionary is chosen to make it easier to avoid confusion. |

I saw that today Blockchain Transfer fee for Regular is $0.15 !! But usually its between $1.50-$3.00 and this fees amount is not stable. What is the actual reason behind this fees up-down?
The wallets set a fee based on those numbers, but that is not what you have to pay. The fee is completely controlled by the wallet user and can be set as high or low as you like. If you are using a wallet or online wallet that does not display the option for you, then the wallet is choosing and it is choosing based on the numbers that people are indicating here, but it is still the software that is choosing and only because you were dumb enough to let it control your life and finanaces. But you find the on pop up says that fees is only for miner not for wallet provider. For your view what would be the options to identify it whether it is goes for miners or wallet providers alone. In my transaction I checked the default transaction fee in blockchain wallet. It states that fees is around 0.00075 btc for a transaction. Still I am confused why again they reduced the fees little now. Fees go to the miners. The wallet software just gives suggestions as to what the fee should be, or picks what it believes the fee should be. The fee is based on the supply of space in a block (1mb) and demand for that space (with some stickiness of course). So the reason fees fluctuate is because the number of transactions seeking to be included in a block fluctuates. Recently there have been a lot of transactions (probably spam transactions since they suddenly dropped off) that were filling up blocks and causing fees to rise. |

How about just posting a link (as I've asked 3 times now) to where you advocate "switching to --i instead of ++i"? I am quite aware of what "goes on inside a CPU" and have actually done several CPU designs. Although I think you need to drop the "Buster" since you are just trolling us. Perhaps you should try reading and understanding prior to attacking. I never "argued" with you about --i and ++i. Yes you did, I even highlighted it: Most well written, non-student compilers will handle cases like that and there will be no different between things like ++i and i++ and the code generated except perhaps in a class that obfuscates the operation in some extremely obscure way. Well technically you posted ++i and i++, but this whole time I've been talking about ++i and --i, that was what you were responding to, and you stated that compilers can handle everything, they can't, and that's entry level knowledge. And regarding your "talentless coders talking about credentials" you again seem to have a huge chip on your shoulder. I spoke about my experience - when people come in and start insulting, attacking, denigrating with a lot of hand-waving and a big chip on their shoulder and no specifics, they are ignored (or not hired) in my experience at big (22000 plus people) and small organizations (3+). And rightly so. I think everyone would appreciate specifics instead of baseless, groundless, inaccurate attacks.
Here is a tip, if you don't want to be mocked, next time don't start an argument with: "As someone who has 30 years of experience plus a BS in CS and CE, and an MS in CS (from top 10 US CS/CE programs)" You walked in here knowing you had no idea wtf was going on inside a CPU, thrown out a bunch of titles, made a bunch of false claims while making demands, and you want to talk about etiquette? Your code sucks, everyone else is doing better, I shown you the proof, I pointed you to the right direction, take it or leave it. You're a nothing burger with 50 stickers on it and I simply don't give a shit what you think. |

Perhaps you should try reading and understanding prior to attacking. I never "argued" with you about --i and ++i. I asked for specifics in the code about which you were referring - which should be easy to provide - and pointed out compilers are quite smart about optimizations, but without knowing what code you are referencing it is impossible to review. Easy question: where is this "switching to --i instead of ++i" which you are speaking about? Just post a link to it on GitHub. And regarding your "talentless coders talking about credentials" you again seem to have a huge chip on your shoulder. I spoke about my experience - when people come in and start insulting, attacking, denigrating with a lot of hand-waving and a big chip on their shoulder and no specifics, they are ignored (or not hired) in my experience at big (22000 plus people) and small organizations (3+). And rightly so. I think everyone would appreciate specifics instead of baseless, groundless, inaccurate attacks. Without more detail no one can evaluate whether you are good at coding or just insulting.
As someone who has 30 years of experience plus a BS in CS and CE, and an MS in CS (from top 10 US CS/CE programs), this kind of language isn't a way to (a) make your point, and (b) get anyone to listen to you with any degree of respect.
In open source projects, if you have something like your --i and ++i change, open a pull request or at minimum link to the specific code you are talking about. Most well written, non-student compilers will handle cases like that and there will be no different between things like ++i and i++ and the code generated except perhaps in a class that obfuscates the operation in some extremely obscure way. But, as I said, if it is that easy, please point out what you are talking about.
If greg wants to be treated with respect, he shouldn't begin and end a reply with insults. This --i and ++i is basic stuff and you want to argue about it? wtf have you been doing for the past 30 years?
And it's not just the speed, it's the smaller byte code which allow you to pack more code into the tiny L0 instruction cache and reduce cache miss, which still costs you 4cycles when you re-fetch it from L1 to L0. It also means you can fit more code in that tiny 32kb L1 instruction cache, so your other loops/threads can run faster by not being kicked out of the cache by other codes. It also saves power on embedded systems. This is what I was talking about, the world is flooded with "experts" with "30 years experience" and "50 alphabet soup titles" but still have absolutely no idea wtf actually happens inside a CPU. Only talentless coders talk about credentials instead of the code.
This is not some super advanced stuff, this is entry level knowledge that's not even up for debate. The information is everywhere, this took 1 second to find, look: https://stackoverflow.com/questions/2823043/is-it-faster-to-count-down-than-it-is-to-count-up/2823164#2823164Which loop has better performance? Increment or decrement?What your teacher have said was some oblique statement without much clarification. It is NOT that decrementing is faster than incrementing but you can create much much faster loop with decrement than with increment.int i; for (i = 0; i < 10; i++){ //something here } after compilation (without optimisation) compiled version may look like this (VS2015): -------- C7 45 B0 00 00 00 00 mov dword ptr ,0
-------- EB 09 jmp labelB
labelA 8B 45 B0 mov eax,dword ptr
-------- 83 C0 01 add eax,1
-------- 89 45 B0 mov dword ptr ,eax
labelB 83 7D B0 0A cmp dword ptr ,0Ah
-------- 7D 02 jge out1
-------- EB EF jmp labelA
The whole loop is 8 instructions (26 bytes). In it - there are actually 6 instructions (17 bytes) with 2 branches. Yes yes I know it can be done better (its just an example).
Now consider this frequent construct which you will often find written by embedded developer:
i = 10;
do{
//something here
} while (--i);
It also iterates 10 times (yes I know i value is different compared with shown for loop but we care about iteration count here). This may be compiled into this:
00074EBC C7 45 B0 01 00 00 00 mov dword ptr ,1
00074EC3 8B 45 B0 mov eax,dword ptr
00074EC6 83 E8 01 sub eax,1
00074EC9 89 45 B0 mov dword ptr ,eax
00074ECC 75 F5 jne main+0C3h (074EC3h)
5 instructions (18 bytes) and just one branch. Actually there are 4 instruction in the loop (11 bytes).
The best thing is that some CPUs (x86/x64 compatible included) have instruction that may decrement a register, later compare result with zero and perform branch if result is different than zero. Virtually ALL PC cpus implement this instruction. Using it the loop is actually just one (yes one) 2 byte instruction:
00144ECE B9 0A 00 00 00 mov ecx,0Ah
label:
// something here
00144ED3 E2 FE loop label (0144ED3h) // decrement ecx and jump to label if not zero
Do I have to explain which is faster?
Here is more on the L0 and uops instruction cache: http://www.realworldtech.com/haswell-cpu/2/Sandy Bridge made tremendous strides in improving the front-end and ensuring the smooth delivery of uops to the rest of the pipeline. The biggest improvement was a uop cache that essentially acts as an L0 instruction cache, but contains fixed length decoded uops. The uop cache is virtually addressed and included in the L1 instruction cache. Hitting in the uop cache has several benefits, including reducing the pipeline length by eliminating power hungry instruction decoding stages and enabling an effective throughput of 32B of instructions per cycle. For newer SIMD instructions, the 16B fetch limit was problematic, so the uop cache synergizes nicely with extensions such as AVX. The Haswell uop cache is the same size and organization as in Sandy Bridge. The uop cache lines hold upto 6 uops, and the cache is organized into 32 sets of 8 cache lines (i.e., 8 way associative). A 32B window of fetched x86 instructions can map to 3 lines within a single way. Hits in the uop cache can deliver 4 uops/cycle and those 4 uops can correspond to 32B of instructions, whereas the traditional front-end cannot process more than 16B/cycle. For performance, the uop cache can hold microcoded instructions as a pointer to microcode, but partial hits are not supported. As with the instruction cache, the decoded uop cache is shared by the active threads. |

What you're seeing here is someone trying to pump his ego by shitting on other things and show off to impress you with how uber technical he is-- not the first or the last one of those we'll see.
What you're seeing here is someone trying to defend obvious bad design choices. ... --i instead of ++i ... Fix your silly shit instead of keep talking about it.

Even the blind can see that crypto Currency is making people millionaires all over the world just because they present the holders of such currency with the financial freedom and opportunity to accrue large amounts of wealth base on currency investment . But my question is that, is it late to buy bitcoin? Should i wait maybe bitcoin price will decline after 1st August meeting? Please i will welcome your advice so that I can make my decision on crypto currency investment.
People have been saying "it is too late" since 2010. Timing bitcoin price changes is nearly impossible. Every time, from $0.10 to $1 to $10 to $30 to $100 to $500 to $1000 to $1500 to $2500 has been "too late" and a "bubble" and "tulips" to someone, somewhere. Each time we heard, it won't go higher. "$1000 is a pipe dream" etc. |

In recent months I have tried to avoid listening to the opinion of these analysts because in the past I believed in an analyst and lost my precious money
...
I'm doing trade with few bitcoins until August, I want to avoid losing bitcoins
You are right to ignore the analysts - they don't know more than you do and it is just their guess. The so-called experts and professionals have been saying terrible, negative things about Bitcoin since 2009 and they have been universally wrong when they've been dismissing it. |

Following China, South Korea and Japan, India will likely emerge as a major bitcoin exchange market in the upcoming months. Since early 2017, the Indian government has expressed its optimism towards the rapidly growing Indian bitcoin industry and exchange market. Amidst financial instability caused by the demonetization of 500 and 1,000 rupee banknotes and the shortage of cash in tens of thousands of ATMs across the country, the general public is adopting bitcoin as the alternative financial network, a safe haven asset and a digital currency. http://news.8btc.com/mainstream-bitcoin-adoption-in-india-is-imminent-amidst-financial-instabilityLet's hope so. The Indian governments demonetization of 500 and 1000 notes just showed how the ruling class there doesn't trust the citizen. 500 rupees is about $7.71 or 6.80 Euro and the fact that the Indian government's politicians think that is too much money to have in cash just shows their true motives: control the Indian population for their own benefit. |

Hi all, Does anybody have any experience with NanoHas? The site looks good and it's easy to get started, but I am wondering it's legit for using it as cloud mining service. Regards, Jorrit This seems off-topic for Dev and Tech, so you might move it. Likewise, adding a referral link to the post makes one question if you really care about the answering aren't just referral link spamming. Finally, a simple google search shows: https://bitcointalk.org/index.php?topic=1726695.0 |

Haha, thank you! I installed VeraCrypt, it's cool so far.
Sorry, but changing OS isn't an option. Our software usage at Uni heavily builds on Windows. But I usually lock to log in when being away + have good log in password.
Also, CD/DVD drive is disabled.
I won't tell them about my crypto business and will look out for shoulder surfing, those are some nice tips, thanks!
Since I've to move in today, I don't have the time buy that protected case that you were talking about.
But I could use some software to protect my USB ports. Something that prevents malicious autorun if they happened to plug-in something funny into the USB ports or SD-card reader.
What could I use?
You could always consider dual booting and use Linux for btc and windows for other stuff. |

How can i recover Bitcoin Wallet.dat file forgotten password, I'm finding best tool for recovering my password.
Likewise, much will depend a lot on the length of the password. If it is 4 vs 40 characters for example. Alpha vs alphanumeric, lowercase, mixed case, etc. The more you can recall the better. |

Please excuse this beginner question. I'm trying to gain a deeper understanding of how Bitcoin works.
It is my rudimentary understanding that the network has a huge amount of hashpower and so difficulty is artificially created in order to control inflation.
My question is: Exactly how is the difficulty created? Is there complex math thrown into the equation which takes a known amount of CPU power to resolve? If this is the case, is this math just garbage that is effectively useless/ discarded?
It seems like a lot of computaional power and energy is being wasted if this is the case.
This explains a lot: https://en.bitcoin.it/wiki/DifficultyThis "waste" provides security. |

Yes, copy the wallet.dat off the drive before doing anything. Preferably making several copies if you have enough bitcoins in them to make it worthwhile to do so.
