I might have... I clearly remember reading about BTC on some forum and setting up a cpu (or gpu?) miner near the very beginning of the network (must have been around 2010-2013). It was on an old PC, but my wife didn't like the fact that is was running 24/7, and asked me to shut it down.
I can not remember wether or not i found a block back then... BTC didn't have much value, and i don't think i completely grasped the concept anyway. Back then, to me, it was just some fun new technology to play with. The PC is long gone, and so is the HD... I might have mined some blocks, i might have dedicated a lot of cpucycles but never hit a block,... I'll never know.

Mijn vraag is aan alle miners, hoeveel euro zijn jullie alleen al kwijt aan electriciteits kosten per maand? Is het nog wel rendabel?
Ik denk dat je je vraag iets specifieker zal moeten stellen, er is namelijk een heel groot verschil tussen verschillende soorten ASIC's en evt met mensen die mbv een GPU altcoins minen. Ook de electriciteitsprijs is voor veel mensen anders. Je kan zelf héél makkelijk uitrekenen hoeveel minen kost... Er zijn tientallen lijsten zoals deze: https://bitmakler.net/asicBijvoorbeeld, op dit moment is de antminer S9 de beste sha256d miner op de markt |

1. It is very difficult to operate own miners. That starts with the availability of the hardware.
2. Cloud mining is another idea. But the real advantages are only on the owner side because otherwise they would use their own service instead of selling it. The risks are completely at the customer.
These points lead to the need of a better solution. I describe what Iam thinking of:
A crowdfunded project (via a TokenSale) could solve that problem.
If the complete profit is spread to the funders (and team, but the major part of the tokens go to the funders as reward), that should work fine and would be a win win for everyone.
What do you think? Wouldn't that combine the advantages operating own mining and of cloud based mining without the disadvantages?
Sure such an operation is always a risk. It could fail at start. But what if it starts correctly???
I fail to see the real difference between this setup and any other ponzi/scam "cloudmining"... The only difference is that the ponzi operator would be selling tokens instead of directly stealing accepting money. I might be missing something here, but i wouldn't trust this setup any more than i would trust any other cloud "mining" operation. Don't get me wrong, i'm defenatly not accusing you. Your heart might be in the right place, you might have honest intentions, i just don't see any more guarantees as any other cloudminer out there. |

I am new here, also a newbies in the BTC world please I really Wanna Know how I can mine without investing any money.
It is possible, there are few miners out there that you can mine for free but as you already know with free miners you need a lot of resources and time to earn few cents. You can try minergate, you can use your cpu or gpu. Goodluck OP  99.9% of the miners that give away "free" hashrate fall under the common denominators ponzi and/or scam |

Thanks for the post! I was wondering if there is a way I could post images as a Newbie. Thiis is the example: https://bitcointalk.org/index.php?topic=2078686.0;topicseen But I realized its a snapshot of a video, instead of the embedded video itself. Apologies for the confusion. Further, I realized scrolling down the page, there are embedded windows for codes. Mind sharing how I may do the same? Thanks again! the BBcode to insert code snipplets is (without the extra spaces) If you have additional questions on how to do this, googling a BBcode reference might help you  [ c o d e ] your code here [ / c o d e ] example #!/usr/bin/perl
use strict;
my $demo = 1;

excellent, this is what i am talking about.
So first I have to send my funds to the primary wallet let's say app wallet, then export the private key to another different wallet e.g. cold one.
thanks,
Indeed, however, it might be a good idear to first check if your primary wallet allows you to export private keys, and if your secondary wallet allows you to import them before transferring funds. If you're uncertain about anything, i always suggest to pick 2 testnet wallets, claim some testnet BTC and experiment on the testnet... Also it is important to tell you that if somebody is able to get their hands on an unencrypted private key, he/she is able to spent all unspent outputs controlled by this private key (in other words: he/she can rob you blind). Always keep this in mind while manipulating private keys!!! |

I have read posts and articles which suggest using sites like Imgur.com to post image links on Bitcointalk.
However, I have seen posts where nice images, and embedded links, even videos, instead of just posting the links. Can someone share how I may do that too?
Thanks!
For the images part: source of these images: post by Lauda: https://bitcointalk.org/index.php?topic=1689727.0Step 1: you have a problem, so it might be best to go the the Beginners & help subforum Step 2: at the very top, you see a post labelled "Newbies - Read before posting"  Step 3: search this post (Ctrl-F in most browsers) for the text "I cannot post images"  Step 4: read this post Step 5: read the rest of this thread, eventough it has nothing to do with why you cannot post images For the second part of your question (embedding videos): could you post a link to an example thread? |

Thanks,
But my query is to save same coin in different wallets at the same time so I can access it through app wallet or through Cold wallet, is this possible?
You're refering to storing the same private key in different wallets? If this IS your question, the answer is "YES", most wallets allow you to export your private keys in some way or another, and a lot of wallets allow you to import private keys... for example, if you create a wallet using bitcoin core, generate a new private key/public key/address, then send funds to this address => you can export the private key that was used to generate this address and import it into (for example) electrum. From this moment, you can spend those unspent outputs using bitcoin core and electrum, but as soon as you use either wallet to generate a transaction using the unspent outputs, the other wallet should no longer be able to use the same unspent output. If you created a transaction from both wallets, using the same unspent outputs, only one of the generated transaction could ever end up in a block, the other one would be invalid... A final note would be that not ALL wallets have the functionality to export private keys, and not ALL wallets allow you to import private keys, but there are several out there that do have this functionality |

what you CAN do, given you have a stationary PC with a fairly new GPU, you can do GPU mining, either mine the coin itself, or use nicehash miner and get paid in BTC. Thats the way to do it.
important notice about this reply: i'm pretty sure sikkan was not implying you could mine BTC using your GPU*, but was rather steering you towards the altcoin-mining subforum * i did the math once, IIRC a rig with 6 fairly decent GPU's would make less than $10/year, without substracting the power costs... I can't find the post right now, but it's somewhere in my posting history. |

Hello, I have seen a seller selling hacked accounts for really low on forum. Can I know is it possible to hack that many accounts without knowing password or emails? Is there any loophole on forum?  The forum's database was leaked in 2015, the databasedump contained the hashed passwords of all users at that time. Since the databasedump has been on sale on a couple of darknet marketplaces, some people started bruteforcing the user's passwords obtained from the database leak. So, if you have an account older than 2016, it was/is a good idear to change your password, cause sooner or later, one of the databasedump's buyers will probably be able to bruteforce your password. Other sources might be successfull phising attempts and the fact that a lot of people re-use their passwords. As for your last question: AFAIK, there is no current loophole in the forum. Only one or two people are able to access the database, that's about it. |

I observed that bitcoin price rose to $4,950.72 on september 1 and since then it has been dropping. As i want to investing in buying bitcoin, i need to know whether the price will still go up or it has started moving down.
There is no way of knowing... Everybody will give you his/her personal opinion, but nobody will know for sure. Only time will tell. I personally think (hope) BTC will recover and see +$5k in the near future, but i won't invest extra fiat into btc right now... |

I have mixed some coins just now, and I too received a voucher code instead of (a) private key(s). Is it because the reserve ran dry? Step 2 mentions that all chips are withdrawn.
So far, every time that you get a voucher instead of the private keys to your chips has been because of lack of chips. I assume that for some reason there is very high demand right now, as it is not usually this way. The only time this wasn't the case was back when the fork to Bitcoin Cash happened, which forced ChipMixer (and many other services) to close and wait for security purposes. You can always email them about it to be sure and try to save your session in case it takes longer than it usually does to top up the chips. Maybe the high demand can be explained by the recent price drop/JC morgan interview/china's ICO ban => people getting scared, wanting to hide the fact that they own BTC, or maybe wanting to mix their BTC before withdrawing? |

You should read about what requirements that Bitcoin wallet needs.
Requirements,
-High-end PC (Intel i7, 64-bit (Windows 7 with full updates), 16GB RAM or more)
-170GB+! You should ready your HDD (SSD recommended) capacity for that big amount of files (Blocks)
-Internet speed more than 50Mbps
-Internet Router setup (UPNP must be on, no firewall filters, no IP filters) for sync on peers
-Anti-virus, you should exclude Bitcoin on scan monitoring
-Encrypt your wallet, don't put any of your informations when making a passwords, some hackers lurking your identity, bitcoin address, etc.
-You should backup "wallet.dat" to your cold storage (USB, Memory card, Disc (Not recommended if not proper used))
-PC Maintenance (CCleaner, etc...)
When you leave your PC/Laptop opened with bitcoin opened, you should monitor it using TeamViewer (Remote PC by using Smartphones).
These specs could be the optimal specs if you want to run an unpruned version of bitcoin core (bitcoin-qt) smoothly (haven't checked tough, but i seems plausible to me), while having hundreds of unspent outputs and addresses and do dozens of transactions daily. If you run bitcoin core with a pruned database, the HDD space will be reduced dramatically, and if you don't mind the fact that core might stall for a couple of seconds once in a while, i'm pretty sure the other specs can be a bit lower to... A different sollution is to use a HD SPV wallet like electrum. I don't know the minimum specs, but i've ran electrum on a 10+ year old laptop without any problems... It uses just a couple of Mb diskspace and runs smootly on windows, linux, mac or andoid... I'm also a bit confused about the fact that somebody recommands to monitor your pc using teamviewer from your smartphone. It's the first time i hear about this... |

 $500,000 moved with a $5 cents fee in a decentralized network thanks to conservative blocksize. The mempool is not empty. We are nowhere near any level of usage as they are trying to make you believe (by they, I mean Roger Ver and Bitmain and whoever else is funding the unnatural spam cycles) Stay strong, hold, and with segwit and lightning network, we will be worth $100,000+ a coin in the next decade. Avoid failing for the hardfork trap by devs trying to offer you scammy solutions like segwit2x, BCash etc. I agree with most of your post, especially the fact that i truely believe over the last couple of months/years a lot of blockspace is used up on artificially created transactions, probably with a hidden agenda. However, the fact that $500.000 moved with a 5 cents fee means just as much as $5 moved with a 5 cent fee... As long as the transaction uses one input to generate 2 outputs, it does not matter how much the monetary value is, the fee should be roughly the same wether or not you're transfering 0.001 BTC or 1000 BTC... |

I'm inserting a picture as described in topics I've read previously.
(without asterisks)
[*img]https://i.imgur.com/QyGETg6.png[/img*]
But it is still inserted as link not as embedded image.
What I'm doing wrong? Thanks for your help.
This question gets asked several times every single day... The search function is in the top right corner, and would have resulted in threads like these ones, explaining everything: https://bitcointalk.org/index.php?topic=2167677https://bitcointalk.org/index.php?topic=1765784.0There even is a section explaining the problem in the stickied thread at the top of the subforum you were posting in: https://bitcointalk.org/index.php?topic=1689727.0The thread is called "Newbies - Read before posting", search this thread for "I cannot post images?" basically, this is your answer: [*img]https://i.redd.it/9h6cqme882cy.jpg[/img*]
How to fix it?
You're still a newbie so you can't post a photo. Make it to atleast a jr. rank. It might be a good idear to lock this topic, otherwise it will get swamped with dozens of people telling you exactly the same thing... |

I usually suggest a bunch of steps, but you seem to have already tried most of them...
- you already restarted electrum
- you tried to switch servers
Some other things you can check/try:
- 2.7.9 is pretty old already, have you tried to upgrade?
- is your disk full?
- are you sure the network connectivity is OK?
- are you running electrum with the correct permissions/user?
To give you some piece of mind: as long as you wrote down the seed phrase, your unspent outputs can't be completely lost, there are always ways to recover your wallet as long as you hold on to your seed phrase...
Thanks for your reply:) I am currently running electrum on a Debian operating system and I think that 2.7.9 is the latest version available for it? The other factors that you have stated to consider are all checked and tried. I have wrote down my seed on paper, I'm not exactly sure where to go from here? I've heard something about 'sweeping' but not sure whether this is available in my case? Thanks:) Not exactly: https://electrum.org/#download2.9.3 is the latest version, it's available for linux, windows, osX and android... On linux, it's actually rather easy to upgrade, just make sure you have pip installed and enter "pip install https://download.electrum.org/2.9.3/Electrum-2.9.3.tar.gz" Since 2.7.9 is almost a year old, it might be your best shot to do an upgrade before trying anything else. If you can't get it to work, i'll help you export your private keys and import or sweep them in an other wallet tomorrow morning (unless you've found somebody else who could help you out by then) |

Hi guys,
I had recently created a new electrum wallet in which I transferred bitcoins from my cold storage trezor wallet. It has been a few hours now and the new electrum wallet has been stuck synchronising? Ive restarted electrum, connected to various other network servers, restored wallet with seed, I don't have a firewall that would prevent any connection. Although, my original 'wallet_default' wallet connects green perfectly? Not exactly sure what to do now, according to blockchain the transaction from trezor to new wallet was successful. Any help would be greatly appreciated!:)
Thanks!

Bitsler username 2 accounts jon_mjay and jon_bank
Both account have been banned after I withdraw my profit from jon_bank account to my blockchain account. Any valid/good reason why? Right now I contacted the support and now waiting for the reply. The bitcoin I used is from my hard earn coins from mining so I seek a valid reason about this matter.
Sorry to hear about your problems, but you do realise this is just a bitcoin forum? The users on this forum are not affiliated with either bitsler nor blockchain.info Your best bet would be to contact their support dept (like you already did) and wait for their reply. If you don't like their reply, you can post all information (+ proofs) in the scam accusation of this forum, at least you can put a bit of pressure on an exchange by exposing them publicly. |

Hey there. So I need a bit of help today. The best I can manage with pictures is getting it hyperlinked through imgur. I want to be able to post the image in the thread so it actually shows.
How does one go about doing that?
you need to rank up first... you're currently a "newbie" and "newbies" can't post images... After you rank up, you can just use the [ i m g ] -tags to post images. If you want to post an image, you can do just that... If you post an image, it won't show up in your post, but if a higher ranking member quotes your post, the image will show up... Also, once you ranked up, the images will start showing on your older posts. |
