Hello.
I am able to install a Bitcoin Server on Ubuntu (Xubuntu).
I was able to install the "bitcoind" server successfully by typing: sudo apt-get install bitcoind.
When I type: cd /usr/bin, I see that the server "bitcoind" is installed in the / usr / bin folder. Then I created a new folder by typing: "mkdir bitcoin" and then I type mousepad "bitcoin.conf" to put the connection parameters to the RPC server of the bitcoin.
Now I try to run "bitcoind" in the Linux Terminal but nothing appears, ie the "bitcoind" server does not start. I wait for several hours and it is always negative. The server "bitcoind" still does not start.
But when I try to retype "bitcoind" in another Terminal, I get as Error: "Error: Cannot obtain a lock on data directory /root/.bitcoin. Bitcoin Core is probably already running."
Thank you for explaining to me how to successfully operate normally "bitcoind".
It sounds like it is running. What does this show (this shows running processes that include the word bitcoin): ps aux | grep bitcoin What about: bitcoin-cli getinfo |

Gold and bitcoin aren't mutually exclusive. Gold is great for some uses, bitcoin would be better if you were (for example) fleeing China or Venezuela and could get your gold across the border. A percentage in each is prudent for many people. And while bitcoin has been volatile, it has been volatile with a huge upward bias.

One other thing to consider in addition to the RAM issues is this, particularly since it is more than 3 years behind (based on the screenshot): Local Disk C: 22.7 GB free
Local Disk D: 19.4 GB free
Where do you have the block chain stored? If on a different disk than C or D, then that could be fine depending on the space it has. If it is on C or D, you may have a problem at some point there too. |

Hi. I was wondering if anyone has a rough idea how often full nodes reboot and/or how often they go offline for some amount of time (long enough to where they have to get blocks from peers and add to their blockchain)?
Is it common for a full node to be offline for an hour? a week? month? (and then download the latest blocks)
Thanks!
It varies by the node. Mine may be unavailable for a few seconds every so often when restarting bitcoind after building an update. Other people's nodes may be down for hours, days or weeks for a variety of reasons - connectivity issues, hardware issues, etc. |

It will probably come to nothing and is likely a CYA formality but anything is possible. It would be beneficial to many people to have an ETF.

The link mentioned in the one you responded to was bitadrress not bitaddress, FYI. One should always clone and run a local copy, OP. Hi all i have been using paperwallets created at bitaddress for years, but came across this post on reddit, any truth?

Well, you move the security of a 256 bit random down to a user selectable passphrase, which in hard crypto are worthless.
There is no way to memorize a bip38 paper wallet, so you lose the paper its gone.
Very dangerous to spend -> best to sweep the first time it is decoded, and be careful with change.
Lets not forget the most popular bip38 site, bitadrress, is in the control of known scmamers who are incentivized to play games with the random numbers.
The modern paperwallet is generated with paper and dice, and is a bip39 menmonic driving a bip44 wallet. you can easily memorize it and not lose everything with the piece of paper. There is no need for a second passphrase which will always be weak. And they are easy to import into a great number of wallets safely, without the risks of change loss or identity compromise.
Thanks
I haven't seen any proof that bitaddress is in control of scammers or that the source code is doing anything malicious, but I also haven't seen that anyone has inspected and reviewed the code. Also, the online page can be modified anytime, so if someone reviewed it last year and it was changed today, may be a problem. Paper and dice are a great way to go, because its unhackable. So the advice here is good. |

Now its syncronized with bitcoin network  What happens then, so i can use segwit signaling? Nothing. You don't have to do anything; by running Bitcoin Core you are signalling that you are ready for segwit and that once segwit activates, your node will be using segwit. You can't "use segwit signalling". I think OP may be thinking that he can signal SegWit support like he would if he were mining. OP, is that what you are asking or something else? Are you mining? |

Or people will realize that they can stay in bitcoin and don't need to cash out. This could be more serious than it seems at first. Brussels is the capital of the EU and the EU already has a pretty bad stance on cryptocurrencies. If Belgium wants to ban it, it could get through to the EU and other countries could be banning it left right and center.
Western countries banning cryptocurrencies could be a huge chain reaction. If one country bans it, the people who use it in that country will then mostly be using it for illegal activities, which would result in other countries thinking the same thing about people finding potential to be anonymous with it and then more and more countries could be treating it negatively. Belgium isn't a big country but this could have worse implications than we would think at first.

The Core wallet is not an HD wallet, so you can't.
Bitcoin Core creates new HD wallets by default now (since 0.13.x). It won't convert old wallets (yet) though. |

To add to what Danny says, what is your use case also? Are you spending from it often?
Do you have 0.1 BTC? 10?, 100?, 500? Etc. (I wouldn't recommend answering publicly). if you are storing a lot and rarely spending a different storage might be advisable.

The authoritarian Democrat regulators in New York don't seem to understand that innovation needs freedom. It seems unlikely that the lawsuit will end up being pointless given the political structure and judiciary in NY, but it is better to fight the battle than to not do so. |

So about a 400 x rise (400 * $1220) in 14 years. Bitcoin has done much more than that in the last 8 years. Even in the last 5-6 years it has grown more than that. So while it is purely speculation, it is entirely possible for it to happen.
Likely to happen, who knows, possible, for sure.

Remittance transfers are one reason. Bitcoin transfers to foreign countries have nearly doubled in the past 15 years and account for 0.75% of GDP, according to the World Bank.
...
There is a lot of nonsense in this article, notably the quote above. In the last 15 years, Bitcoin transfer to foreign countries have grown an infinite number of times given that 15 years ago was 2002 and consequently there was no bitcoin so 0 bitcoin transfers. 0 to anything is an infinite growth rate. Even discussing bitcoin 15 years ago just is nonsense. As far as price growth, certainly it *could* be $500,000 in 2030. Back in July 2010 you saw people who thought that $50 or $1000 was unreasonable and that it was a ponzi scheme, a scam etc. Anything is possible and if usage grows, it becomes more likely, but it is just speculation. |

what if someday when bitcoin has become the main payment instruments in the world. and how when the Internet network paralyzed. it means that we all can not perform various financial transactions? , is there any solution ?
Use cash. Or gold, silver, and other precious metals etc. If the internet was paralyzed, fiat might be experiencing disruptions too. |

What kind of malware was it? I am also using Windows and am afraid if this could infect my system also.
Can someone please elaborate how to prevent this from happening?
Check out this: https://bravenewcoin.com/news/bitcoin-stealing-malware-evolves-again/If you have malware, as others have stated, you won't get your coins back, there is no one who can "fix it" for you. As far as the "maleware" problem, if it was "femaleware" what would've happened.  Thanks for sharing this information but it is wrong to say that it cant be fixed.The same article that you direct me to explain the solution. Considering that the risk level of this trojan is "very low,” Symantec claims that it is "easy" to remove. The security company has already created and deployed the first threat definition for their software, which will detect and remove Trojan.Coinbitclip.Fixing the computer to remove the virus is completely different from returning the bitcoins. Removing the virus may be easy, getting the people who stole the bitcoins to return them will be very difficult since there is no central authority to contact who can "fix it" which was what OP asked. |

I have a wallet backup before it was online what is private key? is it the password i used on wallet creation - if yes i do have i expected to see balance = 1.806 in the wallet and a transaction there Ok, that is what is there, if you check the link above. This sounds like the bitcoins are "there" but that your installation of Armory isn't displaying them. (Always make sure you have at least one, if not several, backups of the wallet because without it you would lose the bitcoins). As far as the password, there is a password to protect the wallet and then the wallet itself has private keys which allow you to spend the bitcoin. If you have the wallet, then it should have the private keys which Armory (or another wallet) will use to control your bitcoins. I am no Armory expert, but it may be that Bitcoin Core (which Armory uses) is still synchronizing with the network and your coins will be displayed by Armory once Bitcoin Core fully synchronizes. |

I made three withdrawals today at * 13:05 * 13:47 * 14:22 Not one of them have been confirmed yet. Here is the blockchain address https://blockchain.info/address/1JmdS4rtxV1xjS7E2CUzR7zkEs56B2CPfyWhat is going on? How can it take more than an hour to get a confirmation. My coinbase account doesn't show any of them, even under pending. Also: What in the world do those red buttons with negative signs mean? I didn't send any money from my bitcoin address yesterday. Edit: Wow, I even included a transaction fee of 100 sat/byte. This is ridiculous Low fees mean slow confirmations - there are a lot of transactions ahead of you. Things like SegWit would increase the number of transactions per second, but some miners are blocking it. See: https://bitcoinfees.21.co |
