Hello Everybody !
I am a French Student in a Business School, and currently working on BitCoin
On a last topic, I asked if it is possible to monitor or at least reduce the price volatility of BTC, but it seems not to be the case (or in a very hard way so)
Now I have another question: are there ways to reduce / or at least to limit the risks for a company when a sudden fall in price happens ?
Like a financial package, or baskets of stocks ...
Thanks for your answer !
Quentin
Just like when there a fluctuations in value in the dollar/euro or euro/yen or whatever currency pairs, you can hedge against it. It is more difficult with bitcoin right now, of course, but if/when the bitcoin etf is trading, it will be easier. Alternatively, you could use a payment processor which immediately converts to fiat. It really just is a question of the amount of risk you want to hedge and the amount you are willing to pay to do so. |

Hello,
So I tried to send a blockchain transaction. It went successfully, but the only problem with that is there isn't a confirmation after waiting 3 hours. What could I do about it, to get the confirmation there?
Regards
Also, what wallet are you using? Did you mean using blockchain.info? It is unclear since all transactions that are confirmed with bitcoin are on the blockchain. |

It sounds like you are talking about the price of bitcoin and the number of bitcoins that are traded on an exchange causing a price drop. Exchanges don't trade their transactions on the blockchain until someone withdraws their bitcoin from the exchange, so you wouldn't see a surge in volume on the blockchain. In short, it is unlikely in the extreme that you would see a surge in volume on the blockchain coinciding with the surge in volume and drop in fiat price. (It seems like the drop was due to another PBOC meeting with exchanges, see e.g.: https://bitcointalk.org/index.php?topic=1782476.0) |

'an “un-American” policy'
Just calling something "un-American" doesn't make it so. A policy of ignoring the immigration law already on the books is arguably 'un-American'. If it truly was about a "belief system", why were only 7 (out of ~50) Muslim countries on the list? This guy seems uninformed.

You might give this a try: apt-get install libboost-all-dev
And see if that helps. I have compiled 0.13.x on Ubuntu 16.04 successfully. Is that the version you are working with? If not, you could try something like this (iirc): ./configure --with-boost-libdir=/usr/lib/x86_64-linux-gnu |

"Use the internet to find public data" - using TOR? New sessions each time? (to avoid someone monitoring your searches or your ISP monitoring your downloads)? Security through obscurity is worrisome. Seems complicated for the benefits.  I have invented a new way of gathering entropy, in order to generate keys from it, I it all described here in detail: https://steemit.com/security/@profitgenerator/generate-secure-random-passwords-or-private-keysIn summary the method is this:- Use the internet to find public data on it that has large information content: files,music, videos, etc.. , or add your own if possible
- All files kept as secret as possible, for obvious reasons, if we want this to be our entropy source
- We gather X number files from a search engine using random keywords, we gather another P number files , where X = P
- Instead of using XOR, due to fears of short key, we just encrypt all the P files with AES256CBC with separate keys generated with the OS's default RNG, the AES256CBC encrypted files will be E
- Then we take the 512 bit hash of the E files, add a random salt to each of them, and use these as separate AES256CBC encryption keys with which we encrypt all the X files separately with AES256CBC
- Then all encrypted X file are already a unique good source of randomness, then we put all X files in a .tar file, and this is our MAINENTROPY.tar file
So when we just want to create a password, we just take the SHA1,SHA256, or SHA512 bit hash of the MAINENTROPY.tar file and that will be our private key. After use, we just add another random file inside the archive, to act as a salt or nonce, and produce a new unique hash next time we use it.
What do you think? |

It is bitcoinfog.org...
The block chain was clogged with more than seventy five thousand unconfirmed transactions for the past fews days and so is the delay and more over the fees was really low and it looks like your case is settled . You can now close the thread....
Since you said you were using bitcoinfog.org wallet and i do think it is a bitcoin mixing site, i am not sure about it,if you are not seeing your money in your account then you should contact their support.Bitcoin transactions are reversable and the answer is no if you sent the coins to a wrong address.
Perhaps you didn't read the message, but that was not the issue. He stated that it had 400 confirmations, but the receiving site hasn't acknowledged it. Likewise, bitcoin transactions are NOT reversible. About the only things that the OP can do are: (1) try and contact their support, (2) wait, (3) hope. One person on the page linked above said they got their money, it just took some time. But, who knows. |

...shed with 11,000 bitcoins... Hmmm. Bitcoins are bulky and do take up a lot of space, I am surprised that they could fit 11,000 in just a shed. /sarcasm They were talking about the machines that were used in mining the bitcoins in this typical looking shed from the outside  : "Equipment Taken To Venezuela More than 14,000 of the bitcoin machines were available for sale in August 2015, of which 11,000 were acquired by Andres Carrero and transported allegedly to Venezuela, according to criptonoticias." Clearly. But they did t write that. |

Bitcoin is a ridiculous solution to the Venezuelan currency crisis. The people want to move to a stable currency, not a crazy one. Bitcoin may find its calling in the next few years, but this won't be it.
They definitely wouldn't want one like the "stable" bolivar fuerte. Anyone who can wants something that will preserve their wealth (if they have any left). Gold, goods, or bitcoin. Bitcoin's advantage is that it can't be confiscated by the totalitarians in charge. |

Hi, the subject says all. I have pywallet with gnuwin32 and pywallet.py with python, but when I click on them they start show a syntax error for seconds and the program close again. Here is a screen of the error I got:  What is wrong? What version of python are you running? What version pf pywallet? What does line 852 show? This? |

Economists who call bitcoin a pyramid scheme clearly disqualify themselves from any serious discussion going forward. (Particularly one like Krugman who is a propaganda tool of the totalitarians in power around the world).
Most "authorities" don't like bitcoin because it gives people power that they can not control..

The less a country believes in freedom, the more it fears bitcoin (and other p2p initiatives). When the authoritarians, socialists, communists and other totalitarians can't control money, they can't control people and that is their goal.
India, Venezuela and others are perfect examples. India has many smart people who must realize that India's authorities dislike gold and bitcoin for similar reasons.

Thank you Danny for all your advice.
Regarding hardware wallets do you perhaps have any preferences.?. I've just been looking at the Ledger Nano S.
Danny had great advice (as is usually the case). A hardware wallet can be another good option. |

Thank you for your quick reply.....I think I'll wait for the next version to see if moving to HD is any easier...:-)
Makes sense. Just keep backing up. 😀 |
|

I think I might know the answer to this but wanted to make sure.
I am running the latest Core wallet and have been making regular encrypted back ups....now if I were to change my encryption password and then make a new backup would that render my old backups non assessable and usable to someone who found them but only knew the old password and not the new one ?.
I hope that makes sense...:-)
If someone already had a copy of the wallet (or obtained an old backup of that wallet) that was encrypted with the old password and you changed the password to a new password, they would still be able to access the old encrypted wallet if they had the old password. |

Ah that's good news thank you for the replies....
I'm using the latest version of Core and have been backing up after *every* transaction which is obviously taking the ''back up regularly'' mantra a bit too far...!!.
Thanks again.
Did you create the wallet with the latest version of Bitcoin Core or a previous version? Be aware that if you created the wallet with, say, 0.10.x or 0.11.x or whatever, just updating to 0.13.x won't change your wallet to a HD wallet. You are right though, backing up after every transaction is probably overkill. I'm sorry I'm afraid I'm a bit confused ...the Bitcoin Core wallet I have is... V 0.13.1 ... and I have been updating this for the last few years whenever a new version comes out. So do I need to change to a HD wallet..?...and if so where do I obtain one from please ?. If you created the wallet with something below 0.13.x just updating to 0.13.x won't change your wallet to a HD wallet. It will remain the old wallet without the HD component. If you want to use a HD wallet, Bitcoin Core 0.13.x and higher will provide one, but you have to move to the one. There are some instructions here: https://bitcointalk.org/index.php?topic=1610647.msg16176943#msg16176943If you wait until 0.14.0 then the process for migrating to the HD wallet *may* be simpler. |

Do you think the price may reach $2000 a piece. I will not believe that until we reach the all time high. We almost reach the all time high the last time we pump. And the PBOC started to do some actions to regulate. But we really cant say whats the outcome of price and i dont see the connection of this political tentions between this two country that will directly influence the price of bitcoin.
People didn't think dollar parity would be reached, and then didn't think it would stay. And didn't think $10 was sustainable. Or $30. Or $100. Or $500. :-) Time will tell. |

Nigeria: An In-Depth Look at Using Bitcoin in a Currency CrisisThis case-study will focus on Bitcoin’s rise in Nigeria. It was partially inspired by a question from Bloomberg’s Joe Weisenthal about what benefits does Bitcoin bring to people living amid a currency crisis. http://bitcoinist.com/bitcoin-currency-crisis-nigeria/ Interesting...not to mention using bitcoin to preserve your wealth from being inflated away. |
