Yes.

If Bob gives Alice a ChipMixer voucher, Bob can still access it. Alice should instantly redeem the voucher at ChipMixer. After that, she can get a new voucher that only she knows (or use ChipMixer to get private keys).

The only problem I see here is that Bob can never prove he paid Alice. An on-chain transaction can prove payment, a voucher leaves no trace. This is of course by design.

Vouchers can be any size.

You're new to Bitcointalk, and don't seem like the typical spammer. That's much appreciated, so welcome

Some advice:
If you're the last to post on Bitcointalk, don't add another post, just edit the first one and add whatever you wanted to add. It reduces spam on the forum, and complies with forum rules.

Now, back to Bitcoin:
Be paranoid! Many people want to get your Bitcoins, many people have had their Bitcoins stolen, and many more will fall victim to theft. There are a few people I trust, but in general it's best to assume people would steal your coins if they get the chance. Don't give anybody that chance.

This seems like a good approach to me. Stock market manipulation and inside trading is illegal. In Bitcoin, it just happens in plain sight! Bitcoin can easily go up and down 20% on a day. It took me a while to get used to it, now I just look at big drops as the rich (called whales) trying to get you to panic and sell cheaper. Many people who bought at the top sold $2000 lower last weekend. In case you didn't read that news: there was huge manipulation going on from the Bitcoin Cash guys, attacking Bitcoin by overloading the network with transactions, and in the end the manipulating party gets out much richer.
Trading is a high risk game, where the average inexperienced newbie loses his money.
My current strategy: every time Bitcoin goes up by a certain percentage, I sell a certain percentage of my holdings. I made a spreadsheet that tells me exactly when to sell. This way it doesn't hurt so much when it drops hard, and if it doubles again I still have enough left so I don't miss out on a big increase.

I would suggest to try out different services, see what's available, and see what works for you. Everybody has their own preferences, so you'll get different suggestions every time you ask.
In general, online services shouldn't be trusted long term.

I've never used Coinbase myself. A typical exchange charges about 0.25% fee on every transaction.

Electrum is easy and popular. Remember to be paranoid: Use the real Electrum website, there are also fake sites that try to make you install a compromised wallet. This will steal your coins!
Also remember to not trust just any link you find on the internet (including the link I just gave you: search for yourself, and verify for yourself it's the real site).
Also remember: if your computer gets compromised (which happens a lot to Windows users), your wallet is compromised too. There are computer viruses out there that replace an address between your CTRL-C and CTRL-V, if you don't check carefully, you'll send your coins to someone else.

Several exchanges have lost large amounts of Bitcoins in the past. 2FA isn't going to safe you when they lose your money. Also, many people lost access to their own 2FA, which is another problem.

To read more about wallets, go here: [General] Bitcoin Wallets - Which, what, why?
In general, the safest wallets are paper wallets (for offline long-term storage) and hardware wallets (for easy access). Each wallet has it's own specific pros and cons.

Bitcoin fees can get quite high nowadays. Think of Bitcoin as electronic cash: try not to collect many small coins, it will require a large fee to send them.

Don't let my warnings discourage you, learn the tricks and risks, and have fun!

There's millions of posts to view, I'm pretty sure you haven't viewed them all. Why do you want to "view more"?

Why?

If you can't view a thread, that means it's deleted. If it's deleted, that means it was breaking the rules. Did you read the rules?

This thread is breaking rule #1 already:

Why would Mark Karpeles need $245 million? Five days ago this was published: Mt. Gox Head Mark Karpeles May Gain Almost $1 Billion Despite Bankruptcy.

I don't know how they got away with this. Apparently, instead of paying back with whatever was available in the bankrupt company, he waited a few years until the remaining Bitcoins were worth much more than he owed people.
Basically, he got a loan in Bitcoins that he can pay back in dollars at the price it had in 2014!

Why do you think some fragmentation reduces your overall system performance? It only influences sequential reads, which is something you barely do, unless you're copying large files.
If you create a separate partition on the same disk, the read arm of the hdd has to travel to that location anway, in those cases is can be faster if the data is all closer together.
Your 200 GB partition will be filled soon anyway, after which you'll need to increase it again.

If you really want to increase your system performance, install a SSD.

Both parties simply agree on a certain exchange rate, that's all.

Say you have 1 Bitcoin and I have 100 Litecoins, we agree to exchange them. We can do that right now, but one of us has to trust the other party, or we can involve a third party (escrow).
Atomic swaps replace the trust-part, the exchange rate is still up to us.

You could send a message to https://walletrecoveryservices.com/, see if he can help you. If you have any idea what the password can be, he might be able to find the right combination.

If you're really done trying, you can just upload the wallet to a public location, post the link here, and whoever cracks it first "wins"! It will all depend on your password though, if it's strong enough, it's not worth the electricity you need to crack it.

Correct. Less accessible Bitcoins lead to a lower market supply. Estimates go up to a few million Bitcoins that have been lost, such as this hard drive holding 7500 Bitcoin. If he wouldn't have lost it, he would for sure have sold at least part of it by now, to live a life in luxory.

Stop spamming the forum for Activity!
I just reported a couple of your posts, expect to see it drop more.

Every lost Bitcoin reduces the number of Bitcoins in circulation. The scarcer it gets, the higher the value per Bitcoin. So in a way every Bitcoin owner benefits from this.

Even in Tor Browser you can set your preferences to remember history and accept cookies. This doesn't tell Bitcointalk anything about you, so you're still anonymous. A man in the middle attack is also not possible. If you make this your default settings in your Tor browser, it should work to stay logged in.

You're probably right that it compromises your privacy somewhat, but I don't know how to rate that risk. A simple solution to still have the full privacy when needed would be to use Tor in private browsing mode for sites other than Bitcointalk.

You can create a thread right here in Meta, like this.

That box is meant to report just one post, although I sometimes say "please check his post history".

If you write long stories in the report-box, it will be more work for Mods. If you have many different posts from one user to report, you can report them one by one. Just a short description is enough.

You should stop using your old computer immediately: every write action to the disk reduces the chance of recovering your wallet.dat. Plug the disk into another computer, clone it, and use data recovery from there.

Good luck!

An easy way to wipe it, is simply remove it and then fill the disk with other data. Just copy your music collection until the disk is full, then remove it again.

I have an SSD and HDD in my laptop. My wallet.dat used to be in my home directory, the rest of the Bitcoin Core data is on the hdd. Since the 0.15-upgrade though, Bitcoin Core doesn't allow the wallet.dat to be symlinked outside it's data directory.
I haven't tried to symlink the chainstate yet, if it improves speed I'll go that way. And you just gave me the idea to symlink the blocks-directory, so I can have my data-directory and wallet on my SSD again.
Normally, a program just follows any symlink the file system shows. I disagree with the way Bitcoin Core rejects a symlinked wallet.dat.

Normally, I just keep it running, but when it starts, it takes a while indeed. It does make sense faster access to chainstate can improve that.

I wouldn't be so happy storing it on a USB disk though, that risks unplugging and corrupting your data.

Test results
chainstate on hdd
When starting, "Verifying blocks" takes a long time.
Total time to start Bitcoin Core 0.15.1, and close it directly after popping up: 1m20.391s.

chainstate on ssd
When starting, "Verifying blocks" is much faster.
Total time to start Bitcoin Core 0.15.1, and close it directly after popping up: 0m22.246s.

For testing, I made sure my file cache was empty. All data has to come from disk while loading Bitcoin Core.

I'd say you're on to something
It's much faster, and as a bonus I can have my wallets on my ssd again. Thanks for giving me the idea!

The only drawback is that the chainstate directory performs many write actions, adding to the wear level of my SSD.

Basically, from your perspective, I did this:

You want to move your chainstate, so use some variation to this:
In ~/.config/Bitcoin/Bitcoin-Qt.conf , edit the location of your bitcoin data directory to point it at your USB-disk
You'll need to format the usb disk with a Linux file system to deny other users access to that directory.

Which program did you run on your new computer? I assume you have an old wallet.dat, which would load in a modern Bitcoin Core. This will take a long time to download 150 GB, but it will quite quickly show your transactions from 2011.
If your wallet.dat still works, this is the way to go. There are other possibilities (extract private keys for example), but without more information about what files and software you're using that's just guessing.

If your mykey.txt doesn't hold private keys, your only chance is your wallet. Start searching there.
In 2011 Bitcoin was worth $1 to $10, if you find a few in your wallet you're looking at $7700 each. What made you forget you had that wallet all these years?

This happens sometimes, it's an unfortunate side effect of the unique way ChipMixer works. Chips are prepared before you deposit, and sometimes all chips are withdrawn due to popularity. New chips will be funded soon.

I assume you got a voucher code, right? Just safe the voucher code and try back later.

I know how it feels to not be able to withdraw your funds (it feels bad!), but in this case I wouldn't worry about it. Your funds are not lost.

Hating? Didn't I say "I'm tempted to do this"?
I'm just curious what I'm getting in to, and before anyone can sign any message, you'll have to tell him what message he'll have to sign anyway.
I did misinterpret the part about signing a message, you want to have the wallet itself. Would a private key be enough, or do you want any specific HD-wallet?
As for the diploma part: I'm qualified for this job, asking questions in a job interview is normal. I can't imagine you'll pay 5BTC when someone moves 100BTC back and forth though, so how much are yoou looking for?

So the message won't be "Dear IRS, Trance104 owns this address filled with legit money"?

Who falls for that? I can't think of a single way where a signature from an empty address adds credibility, and if someone shows many different signatures from many different emptied addresses he has no credibility left.

If whatever you're planning to do accepts this, why don't they just ask you to sign from the original wallet?

I'm tempted to do this, 5% interest on my Bitcoins sounds very nice. But it seems very shady too. I guess you can't post what message you want to be signed?

Addition: I just noticed you didn't post for 3.5 years before you opened this thread.

If it's your own PC, you can tick the "Always stay logged in:" box. I can't remember the last time I had to login, that's how long it has been.
I don't use Tor so can't test it, but can't you just tick this box to remember your login? Unless you want to erase your browser history after every session, this should stop the captcha login.
