In some places spam calls like these are common and aren't a sign of a particular scam. Just remember to practice common sense and make sure that the transactions you're making are legit before you send any BTC.

Bitcoin Cash has implemented two way replay protection so any transactions created with a Bitcoin Cash wallet (e.g. Bitcoin ABC) will be invalid to the Bitcoin network and anything created with a Bitcoin wallet (e.g. Bitcoin Core) will be invalid to the Bitcoin Cash network.
You just mean if any new address is generated after August first or any address generated on a bitcoin wallet at all will be invalid to BCC after August first? I'm going to be dumping mine asap too, I will gladly be the first one to test the transactions  . Not addresses, but transactions. Let's say you have 1 BTC at address 1Addr.... After the split, you have 1 BTC on the BTC network at address 1Addr... and 1 Bitcoin Cash on the Bitcoin Cash network, also at address 1Addr.... What this means is that if you were to have a transaction that spends 1 Bitcoin Cash to address 1Xyz..., a type of attack known as a replay attack would't be possible. A replay attack is an attack where someone copies your transaction exactly, and uses it on the other network. In this example, if the replay attack was performed (it can't because BCC has features to prevent it), then your 1 BTC on the Bitcoin network would also move to 1Xyz... (BTC address), even though you only intended to send BCC to 1Xyz... |

Finally I got it working and got my bitcoin address as well. I really am an idiot..... the reason I couldn't get pywallet to work was because I had to write D: but I wrote D:\ by mistake. Thank you to everyone who helped me out.  Any chance you could list the steps you took to actually set up pywallet, for a novice computer user to understand?. I am in the same situation you were in, with potentially 32 BTC at stake. I will understand if you don't have the time or inclination to help. Cheers. Might be a really late reply. First of all, stop using the computer/hard disk that the wallet was on immediately. Every time you write to that disk, you lower your chances of recovery. Using another computer, create a live DVD or live USB for Ubuntu Linux by downloading the Ubuntu install disk file and using a disk burning tool (for DVD) or Unetbootin (for flash drive). Insert that drive into the computer with the lost wallet, and boot using that live CD. Pick "try Ubuntu". Once it's booted up, download pywallet and put it in the Downloads folder. Open a terminal, use the cd command to change directory (if it's in Downloads, cd Downloads will do the trick). Open up the Disks tool and identify the ID and size of the partition that the wallet was on. The ID is something like /dev/sda3. Back in the terminal, run the following command: python pywallet--recover --recov_size 30.1Gio --recov_device /dev/sda3 --recov_outputdir ~/Desktop/recov Replace /dev/sda3 with the ID of the partition you found in the Disks tool. Replace 30.1Gio with the size of the partition that you also found in the Disks tool. (note that pywallet uses Gio instead of GB to mean Gigabytes). If you need more details or live assistance, just PM me or email me at my username at gmail dot com and I'll try to help. |

Why don't you modify the miner program and recompile it, so that it reports data using a saner interface than trying to parse a user-oriented CLI?
|

So it's good idea to rename documents or folders which contain your private keys. Viruses can parse file and folder names but they can't open random files.
No, that's complete BS. A virus can make a system call to obtain a file handle for reading just like any other user-mode program can. If Notepad (or your favorite choice of benign program) can open files on the computer, what keeps a virus from doing so? |

With Vanitygen you can only generate addresses starting with "1", that only require one private key to spend (the one generated by the software).
But theoretically, you could begin constructing various scripts that only you can redeem (e.g. by using an ECDSA signature with a key you generate), hashing them, and seeing if they have the right prefix. |

Wow make sense Here is mine!  3BnY8CnsTWEtWywzhCfkNH2vBgesRKQDDU Looks like the address that you are using comes from an exchange site. You cant sign a message using an address that comes from an exchange site. If i am not mistaken that is from Coins.ph. Better get an address where you can sign a message like in Blockchain.info or Coinbase so that in the future you will not have a problem signing a message. How do you know it's from a certain exchange? It's just a P2SH address, likely multisig (which doesn't support message signatures due to technical limitations). |

You have to change the command line parameters to match those of your system and situation. /dev/sda3 should be the block device where the wallet was, recov_size should be the size of that block device, and output directory should be your actual home directory.

It can be very unsafe in Windows. If you are very concerned about security - use Linux, no network connected, same size USB drive and do low level disk copy such as:
dd if=/dev/sdX of=/dev/sdY bs=2M
where sdX source, sdY target. Be careful, that will destroy everything on sdY
What if /dev/sdX is a bigger drive than /dev/sdY and the key file happens to have been fragmented/moved to the end of /dev/sdX? And why not make bs equal to the underlying physical sector size? If running on a secure offline system you should just be able to use cp and skip the raw disk copy nonsense. |

Yes, I know that. But I need unlimited or more then 40 character pattern.
Lol. Trying to crack the Bitcoin richlist? Just your bitcoin address . Seriously, who has an unlimited version?  Nobody. It's impossible, man. Guys. I just need the programm. Don't tell me please "possible/impossible". I know that programmers can easily remove this limit. I'll pay a tip There's a reason for the limit, as you'll find. However, I can remove the limit for you, if you really want, at your own risk (i.e. results not guaranteed), I can send you source code or precompile for Linux. Send me a PM. |

Write constructive posts. Ranks are based on a score that's the lesser of your number of posts, and the time you're active (roughly speaking, number of separate 14-day periods during which you post, multiplied by 14).

UPDATE:
I create a couple of new addresses and necessary one has appeared after several attempts! great!
Thank you, everyone, for your support!
No problem, happy to have helped. I assumed that the address you were trying to recover was the first one in the pool, it must have been somewhere else in the pool of 100 addresses. |

please need help..
3.24E-5 = ? convert USD
please help me..
About eight cents. Convert scientific notation to standard notation if your calculator can't handle scientific notation, and then multiply by the current market rate (2508 USD/1 BTC). I was under the impression that schools still taught basic mathematics, scientific notation, and ratios. |

If your wallet is not hierarchical determinstic (HD), then there's a pool of 100 keys that are pre-generated and stored in the backup, so the next 100 addresses you generate after making your backup will protected as well. If it is an HD wallet, then every address (not just 100) is protected in this way. Try generating an address in your wallet and it should match the one you generated last time.
Thanks for the idea. I generated a couple of new addresses, but all of them are completely different.. I initially created wallet.dat many years ago with an old bitcoin core version. Unfortunately the address has not been properly backed up then. It was vital that non-HD wallets were backed up regularly, and the documentation didn't stress this clearly enough in my opinion. As jackg mentioned, there might be ways to perform data recovery; you should immediately stop using this computer if there is a chance that the file was deleted, but pieces of it still remain on the hard disk. |

Thanks for the response. Its true I am out of the Bitcoin Industry for a few years, I used to fork my own coin from Bitcoin and edit the genesis block, launch it etc. get it up on exchange and set up games.
But right now this ETH is puzzling to me.
1) It is easy to setup my initial supply and setup my coin on behalf of my company.
But i got this issue, because if I want to create a wallet for e.g 1000 members of my network, attach their wallet to their account (the import data or whatever), then could I achieve this with ETH network using CLI?
As not all of them download ETH program and sync it, they are not so IT savvy, what I could do is guide them on how to import their wallet to the exchange the coin is listed on.
2) If I set an initial supply of 100 million coin, and I would like to send coin to this "1000 wallet address " mention in (1), could this be done with ETH network smart contract token (A token created under ETH network), is the fees very expensive to send this 1000 transaction.
I know if I fork a coin under Bitcoin, I can do this without paying (gas) or whatever that ETH require when doing a transaction.
3) I would like to list my company coin such as Yobit by paying an exclusive fee, if a token create under ETH network, is it able to be listed on exchange easily (easily as in technically not in acceptance)
Thanks for helping answer my questions.
This could be done as an ERC20 token with some modifications. 1) Members can use a tool such as myetherwallet.com on a trusted computer, or a custom GUI you write that interacts with a geth node. You could even provide a node as long as you sign transactions on member devices. 2) It shouldn't be. Depends on what you consider a terrible level of fees. 3) If it's close enough to the ERC20 standard, exchanges should have no problem listing it since it would be a fairly standard operation for those exchanges that already work with Ethereum tokens. |

I see people talking about programs that steal your info off your usb. Please don't listen to these people they have no clue what they saying. Things don't run on your own without you rinning or installing them yourself end of.
Clearly you live under a rock, are illiterate, or didn't think before posting. I spot 304 hits for published CVEs mentioning remote code execution in Microsoft's products alone. Just search nvd.nist.gov for "remote code execution" and you'll see. There's being paranoid, and then there's taking appropriate precautions. Spyware that transmits sensitive data such as cryptographic keys from disks and USB devices is not unheard of. |

When you create a raw transaction, you can always set the fee since it's just total inputs minus total outputs. What language is it written in? I may be able to provide assistance over PM.

There are no such option anymore.  You can only IMPORT bitcoin private keys to it. So if you want to control your bitcoin wallet funds then generate new bitcoin address with private key everywhere and import it to blockchain.info. So if they go down in one day you will able to continue managing your coins Or export the seed and import it into another wallet. You get the added protection of securing all future keys derived in the wallet with that seed, since it's an HD seed (seemingly BIP39 compatible) |
