2. Exchange Cash for BTC in person. (without using Facebook or a way or that person to track who you are)
Although I've never used it myself, Localbitcoins is the place to go for this. Find a trusted seller, deal in cash. Some even offer "cash by mail", which requires your complete trust in both seller and postal service. Note that sellers will also be very careful when dealing with first time buyers. Scammers work on both sides of the trade. taking someone with you is also a good idea.
For the seller on the other hand it's a big red flag if you arrive with 2 big guys  |

Allow me to be sceptical! So you've spend a few hours on a website and a whitepaper, and want to sell made-up tokens. Once you've received $17,000,000, you're going to create a blockchain and give 1 made-up token each day?
I am familiar with the term basic income. I'm also familiar with random ICOs created for the sole purpose of earning free money. This looks like the latter to me, and has nothing to do with a basic income. Well, maybe for the creators themselves.
Meanwhile you use popular big names like Musk and Zuckerberg, who have nothing to do with your little project.

You guys are fucking hilarious. All of this over a spot in a signature campaign. Don't you have other things to do than making alt accounts and shilling a manager. In my experience, you must be doing something right if butthurt people start chasing you like this. Lauda has the same problem on this forum, I experienced it too being a Mod at Rollin. @DarkStar_: this is the reason I changed my threads to self-moderated. That delete button is lovely for every offtopic post (including this one from me, I realize that). @The drama: as DarkStar_ said, create a thread in Reputation if you want, this isn't the place. I love reading some good drama while eating popcorn, I just didn't expect it in a Signature Campaign thread. |

A PC updated and maybe even using linux and nearly 99% offline for maybe 5 or so alt coin types with lower levels of investment and using only the dev recommended wallets. 1% online is enough for trojans to patiently wait and send all your money away the moment you go online. Any wallet that has ever touched an online device should be considered a hot wallet. That being said, I keep my altcoins in a Virtual Machine on Linux. My altcoins aren't worth enough to go through the hassle of offline security. From your description, it sounds like you want to use your PC the way I use USB disks: online 1% of the time only. If that's the case, why not use a different USB-disk/stick for each wallet? At least they can be separated and used only one at a time. Needless to say: always ensure you have sufficient backups. |

What you're asking is like saying you want to send an email to a post office box. You can't.
Send an email, ask for their Bitcoin address, send the Bitcoins there. That's how Bitcoin works.

The fee is much lower than required for a fast confirmation. See https://btc.com/stats/unconfirmed-tx . Usually, fees get lower on Sunday, so I expect it'll confirm within 48 hours. |

In june & July I bought Digibyte & Stratis & Siacoin with all my bitcoins, till now I lost almost 80% You should realize why altcoins are created: they're created to get your Bitcoins! Whoever sold you their made up altcoins got his profit. What can I do, HOLD or Sell or What!
I've got some alts too (but luckily mostly Bitcoin), and I too saw 80% of the value disappear. I'm holding. History shows altcoins usually go up again at some point. Unless the altcoins are totally forgotten, as the creators can just create the next hype to get your Bitcoins. |

I have a physical bitcoin I would like to use as cold storage and it would be nice to memorize the priv key. I assume a physical Bitcoin has a random private key, instead of derived from a seed. So this wouldn't work anyway. |

Read Bitcoin Address start with 1 or 3 for the answer to your question. Seriously, Exchanges addresses are not real Bitcoin addresses because you haven't the private key.
Then, they can made addresses they want, whithout Bitcoin protocol rules compatibilities.
You couldn't be more wrong. |

my goal is to generate a seed for Elctrum that contains a private key that is already known. You'll need a brute-force attack. With 2048 possible words, and 12 words in total, that gives roughly 5*10 39 possibilities. You won't find it. As far as I know, having 1 derived private key doesn't help you find back the word seed, it wouldn't be as secure if that would be possible. |

HumbertDice was last online on September 25, he tried to sell his account, and his password and email address were changed recently. I don't expect him to answer this thread anymore. Some tips:Check https://btc.com/stats/unconfirmed-tx for the current best fee, or for a reasonable fee if you're not in a hurry. Free accelerators:1. Use ViaBTC (usually only available every hour on the hour) to accelerate any transaction with a minimum fee of 10 Satoshi/byte. 2. Use http://confirmtx.com/ for every transaction of no more than 500 bytes, the fee on the transaction can be lower than ViaBTC accepts (I haven't tested this service by myself yet). Update: confirmtx.com works for me. |

I've come across with some post about using virtual machine to store your private key and make it as a cold storage wallet for your crypto coins. I've never read this. I use VMs to install altcoin wallets I don't trust, to protect my host OS (and even this is said to pose a risk to the host OS, as malware might escape the VM). My question is, it is safer to use VM instead of your original OS? Once your host is compromised, it's best to assume your VM is compromised too. So no, it's not safer. is it advisable to store my bitcoins to a VM? I wouldn't do it. increasing my immunity against the hackers of the private key and wallet? If you want cold storage, you should start at it's definition: "Cold storage in the context of Bitcoin refers to keeping a reserve of Bitcoins offline." The keyword is "offline": any private key that has ever touched anything online, can't be cold storage anymore. Unless your host OS has never been online (in which case hackers are not a risk), you'll have to re-think your setup. Easiest and cheapest cold storage: print paper wallets offline, from a LIVE Linux DVD, on a dumb offline (laser)printer. |

random forks boosting bitcoin, important is what happens after this settles...
At the previous fork (early August), the price went down before the fork. Many people must have panic sold out of fear what the fork might bring. Right after the fork, the price went up a lot. With this in mind, it seems many people are expecting a rise after the fork, which means it rises already before the fork. I'm curious to see if the price will continue upwards after the fork. If all upward pressure is now released before the fork, it could go down again after the fork. Then again, in crypto, I'm getting used to that. Up and down 40% happens so often, it's just "normal". |

but things are now different. This is a very dangerous assumption in any investment! More people into Bitcoin = more strong hands. I've counted 5 big drops (in Bitcoin) this year, and each time Bitcoin reached a higher point after that again. Realizing the whole dumping thing is manipulation to get people to panic sell at a lower rate makes me feel much more confident it will just bounce up again eventually. You cannot compare it with history. If history taught us one thing, it's that history repeats itself. Bad thing is that alts are suffering, but as I said - the ones who deserves it will eventually flourish as well.
I too got into alts at a very bad moment, right after many alts went up 10 to 100 fold. Since they've lost more than 80% already, I just keep them. Another thing history has taught me is that alts go up every few years, and once they do, I'll sell some. Not all, just a bit. |

I believe my thread makes more sense now. Bitcoin is skyrocketing and alts are being dumped.
I kinda expected Bitcoin to shoot up a lot once it really broke the $5k barrier. It had been stuck just under it for a long time now. The same happened at $3k, and the same happened at $800. If it follows the same pattern, that would mean $8k soon. |

Imagine I want to consecutively mix some bitcoins. I mix 1 BTC, then after a week another 2 BTC.
How can I be sure that the 2nd time I won't receive my own bitcoin from 1st mix? You can't be sure about that, but it doesn't really matter. I've asked a similar question before, this was the response: There is no guarantee, there is chance and receipt. Chance means that if you send 1 BTC out of 100 BTC pool, you have 1/100 chance to receive the same coins. Even if you would receive the same, there would be no proof they are the same. It is like throwing a dollar into cup of dollars. Even if you pick the same one, they are fungible and there is no difference whenever you pick any of them. Receipt is a signed proof you have received funds from ChipMixer. bitmixer.io had "codes" that would tell them not to mix my previous bitcoins with following.
Or so they said, but they also said to delete all data. Read this comment in their thread about it: <playin' devil's advocate; not critical of service but seek answers> https://bitmixer.io/faqs.htmlWhat is a Bitmixer code?
After your first exchange you will receive a special Bitmixer code. This code makes sure that you will never receive any of the previous coins you have added to our reserves in any subsequent transactions you make with Bitmixer. In other words this ensures that you remain untraceable. Day 1: I mixed U$100 worth of bitcoins and received a Bitmixer code so that when I mix subsequent coins I won't received what I previously mixed back. Fine! 48 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two days prior. Fine! 36 Hours Later: I mixed another U$100 worth of bitcoins and received bitcoins back which none were of what I've mixed two transactions prior. Fine! Question: How were the last two transactions achieved given the following? ... http://themerkle.com/news/interview-with-the-owner-of-bitmixer-io-a-high-volume-bitcoin-mixer/Our servers are located in a country where US authorities can’t get access to the server without a local court order. Bitcoin is not considered as money here, so we can’t be a money-laundering service. We use encrypted disks. We delete all order data after 24 hours. We completely erase old bitcoin addresses from our wallet after coins are sent out. Even if the server is seized, they will find nothing. Clearly, my Bitmixer code remains on file attached to bitcoin wallet addresses I've previously used, else there would be a strong possibility of me receiving some of the coins back that I may not want attached to me, but that would be an impossibility given that ALL order data is purged from your system within 24 hours, as stated above, resulting in the 3-LAs et al. finding nothing. Further, I'll be paying you a fee to mix coins stemming from a nefarious act with the strong possibility that I'll be receiving coins stemming from a nefarious act tens of times worst than what I'm tryin' to hide. Surely, wouldn't that bring the feds to my door a knockin' a helluva lot quicker? It'll be pretty embarrassing for me to defend myself if accused of running a underage goat brothel when in fact I ONLY pimp out adult chickens and occasionally a matured goose (soon to pimp ducks - drakes and hens). Humor aside, I look forward to your reply, devs. Bruno Three weeks after this comment, BitMixer closed. |

Native Dutch here. See LoyceV's Hero Campaign/Services Portfolio for my previous translations on Bitcointalk. I do not use Telegram, if interested, please contact me here. Many Dutch translations are wrong on context. Example: blockchain.info uses the Dutch verb "Blokkeren" instead of the word "Blok". In English this means the verb "to block" is used here when they mean a Bitcoin block number. In English it's the same word, in Dutch "it depends". If you pick me, please provide enough context if loose words need translating. |

should i split my btc from bch before the bitcoin gold fork?
I'm not doing it. When I want to spend them, I'll spend them in this order: 1. First move all Bitcoins 2. Import private key into Electron Cash on a Virtual Machine to move Bitcoin Cash 3. Import private key into whateverclient on a Virtual Machine to move Bitcoin Gold 4. Never use that address again, but keep the private key just in case. If the premining-rumors are true, it could be Bitcoin Gold's snapshot has been taken already. In that case splitting coins now makes no difference. |

I have throughput to download it faster, so this is not my bottleneck. If you're using an old HDD, that's the bottleneck. Using an SSD is much faster. Depending on your system, CPU power can also be a limitation. Check your system load to see what is limiting your download. Would be great, if there was an official pruned blockchain available for download.
The pruned version could be made for example from block 450000 and correctness could be verified with a hash sum. Who would you trust on this? You could end up on a side chain without knowing for sure. It would be quite easy to set up though, get a VPS and take a daily snapshot. The beauty of running Bitcoin Core is not having to trust anyone else, if you don't want to download the full chain, why don't you use for example Electrum? At some stage we will have to go that way or the blockchain will grow too big to be practical.
I tested a pruned version to a ramdrive less than a year ago, it was mainly limited by my (not so modern) CPU speed, and took 24 hours. It was a lot faster than pruning to disk. At current growth rate, disk space and network speed increases much faster than Bitcoin's blockchain grows. |

Can i ask only about one thing - is it safe or not? I mean do the private key is safe and only i can see it or...?
Vanitygen is as safe as your own computer is. If your computer is compromised, so is your key. To go full paranoid, you can generate a random Bitcoin address offline, from a Linux LIVE CD, and use split key to generate a vanity address. Full instructions: Step 1: Goto https://www.bitaddress.org/ move your mouse/type in the field until it shows 100% and wait a second. Step 1.5: Download the page, verify the download and run it locally *. Step 2: Click Vanity Wallet click the Generate button next to Generate your "Step1 Key Pair"Step 3: Save the private key somewhere safe. You will need it later when I generated your partial private key. Step 4: Once you create your partial private key on your online computer, go back to bitaddress.org and click on Vanity Wallet. Step 5: Go to step 2 Calculate your vanity wallet. In the first field put the private key you saved and in the second field put the partial private key I gave you. Click Add and Calculate Vanity WalletStep 6: Copy the Vanity Private Key (WIF) and import it into your preferred wallet. Credits to shorena for most of these instructions! If something doesn't work as expected, have a look at this example. |
