It's a feature, not a bug! Bitcoin is meant to be trustless, and it is. Bitcoin wouldn't exist without it, as this is the one USP it has.
If you're in a rush to buy Bitcoin from your creditcard, it's easy: go to an ATM, take out cash, go to Localbitcoins, pay cash for Bitcoins from a trusted seller.

They wouldn't last if they'd do that, scammers would be all over them with stolen creditcards.

This won't happen, since creditcards or Paypal can be charged back, and strangers on the internet can't be trusted.

You should also move this thread to Currency exchange.

I like to run a clean campaign, with strict rules, and zero tolerance for spam and cheaters. I only work for campaigns that I personally trust to be legit. Since you're mentioning an ICO, chances are you won't qualify, but if you stand behind what you're offering, feel free to contact me.

It's not allowed:

Apart from being a possible scam, his bumps are spam, and his thread is plagiarism, as his screenshot is a copy of http://confirmtx.com/.

Vod has recently started making a red list. The only problem with this is that they'll abandon the tagged account and create the next one.

It's kinda cool to see my own work like this!

Now, some comments:

• Post 1 = Post 21, Post 2 = Post 22, and so on. I think your scraper fails to reach the second page in post history.
• My Post 25 is missing entirely.
• You should exclude quotes, Post 2 for instance shows _Arnold_, which is the name of the person I quoted.
• Some of the small fonts are impossible to read. If you limit it to 4x5 images, they can be a bit bigger without getting wider, and it fixes my first comment at the same time.
• Post 12 shows AMSo, I can't see that in my original post.

I'll bite, do me please: ID 459836.

I've recently started using it, and so far, I'm happy with it. You can use in-app Shapeshift to convert it (which I haven't tried yet).
Note: sweep your Bitcoin (the most valuable one!) first. Once confirmed, do Bitcoin Cash, then Bitcoin Gold. After this, you can add BitCore to your list.

Slowing down your visitor's computer, heating up his hardware, and increasing his electricity bill sounds like a great way to give your visitors the finger indeed.
It's also a great way to get your website on browser-mining-warning-lists.

Forks are simply the next in a long line of money makers:
First, people felt they missed out on Bitcoin because they joined late, so they created their own altcoins (now called shitcoins). They were usually premined, so the creator earns 1 to 90% of all future value.
Second, they came up with random ICOs that promise a lot and produce nothing. Thanks to code is law master-of-forks Ethereum they now don't even need to create a coin, they just make up a token. After hyping it, they sell it. That means ICOs have 100% premine! Most ICO websites look a lot alike, I wouldn't be surprised if many are created by the same small group of people.
Third, now that most people know most ICOs are just scams, and authorities are cracking down on them, the next thing is forking Bitcoin. After many years of fighting about scaling, the community is divided. There's the very rich, who want very expensive blocks, and there's people who can't get their transactions confirmed. It started with Bitcoin Cash, created to FUD Bitcoin and give some very rich guys an opportunity to pump&dump.

Then Bitcoin Gold, which was only created to give the creators a 200,000 coin premine.

There's now talks about Bitcoin Silver, Bitcoin Platinum, and this Super Bitcoin is just one of many more in a long line. The 210,000 coin premine is of course a great way to become very rich out of nothing. The Bitcoin Gold premine is now worth about $50 million, even if Super Bitcoin just gets 10% of the value of Bitcoin Gold, it's enough to be set for life! Or to start preparing the next fork already.

If I remember correctly they didn't last...
I wouldn't trust any exchange that claims to do anonymous fiat withdrawals. That's very shady, and even if they're not trying to scam you, authorities would quickly shut them down.

If Forbes.com publishes an article, I don't think that necessarily means Forbes.com stands behind the article. This article for instance was written by Chris Kline ("Co-founder and COO at Bitcoin IRA"). Given his job description, of course he has high hopes for Bitcoin next year.

His number his arguments
(Forbes.com doesn't show the last 2 pages, so I can't see the next arguments)

Although I agree #2 can result in a large flow of money into Bitcoin, I don't expect #1 to happen. Bitcoin doesn't scale, blocks are full, transactions are expensive, and it simply can't handle more new users. Bitcoin currently has less than 25 million funded addresses. Most of them hold less than 0.001BTC, which currently isn't even enough to pay the transaction fee you need to use it.
That leaves just over 11 million addresses in use. I don't know how many addresses the average person uses, but it will be at least a few. That leaves at most a few million people who own Bitcoin, and this has pushed Bitcoin to it's limits for a long time already.
Without a scaling solution (Lightning Network?), Bitcoin's adoption simply can't grow much.

No.

(see what I did there?)

How did this happen exactly? Was it someone at your house, showing you his wallet? I've heard about fake banking apps (in the Netherlands), used to pretend to pay someone when buying goods. A fake Bitcoin app would be new to me.

The negative balance on blockchain.info only happened when they made the second payment (the real payment).

With the current high fees I wouldn't assume it confirms before it's dropped from mempool. I have an outgoing unconfirmed transaction for 3 days now, I'm curious to see if it gets dropped (in which case I'll rebroadcast it) or that it just stays unconfirmed until it confirms.

For some reason many people who invest in Bitcoin, still listen to bankers, while one of the best features of Bitcoin is "not needing bankers".
Of course they'll say anything to drop the price, it's pure manipulation. After people fall for it and sell their coins cheaper, the bank buys them. Now they own Bitcoins, they're entering the next phase saying it's "new gold" to pump the price.

Who cares what bankers or anyone else says about Bitcoin? Just realize one thing: they're out to get you to sell your coins cheaper. Or more in general: they're out to get your money, and they are very, very good at it!

JP Morgan is not "reputable", it's the opposite: Is JPMorgan Chase America's Most Corrupt Bank?.

Of course they didn't change their mind, this whole thing was a setup from the beginning.

I doubt it. From my experience: the more often you fail at solving a captcha, or the more captchas you've solved in a small time frame, the harder they get. When you use Tor, you're sharing the same exit node (read: IP) with other users, so all their captcha failures are added to your next captcha difficulty.

I've tried Tor, and it's terrible. And on top of the normal captchas, Cloudflare on many sites adds another captcha. The total process is slow and annoying.

Captchas by now are terrible to solve for humans, while computers get better at it. And a computer has much more patience to solve it!

As a partial solution (I say partial because Cloudflare will still serve you captchas): you can setup your Tor browser to remember your sessions. You could easily create a dedicated Tor-installation that you only use for Bitcointalk, or you can use a private browsing window in Tor when you visit any other site.

PS
I've seen your account in the Copper member thread, and this Copper membership turns out to be an easy way to distinquish between shitposters and serious posters. Not many Newbies post stuff worth reading, well done

This doesn't prove anything: Bitcoins that have never moved are not necessarily lost, and Bitcoins that have been moved can still be lost later on.

i used some standard (Linux) command line tools:
The first grep gets all lines that contain "5000000000", the second grep gets rid of the lines that have an additional zero (aka 500 BTC). The output goes to a txt-file.

Command line tools are very convenient to process large amounts of text, this line takes less than a second.

It's not even a double spend, it was never spend to TS.
If it's a double spend, blockchain.info shows a big warning. Now it shows this:

Note the negative Final Balance.

Blockchain.info has bugs: it is possible to create "transactions" that only show up on blockchain.info. I've seen it before. I don't know how they do it, it seems they only broadcast it to blockchain.info and not to other nodes. This typically shows a negative balance on the address, which obviously shouldn't be possible.
If you try to find the transaction in any other block explorer, it doesn't exist.
I don't know why blockchain.info doesn't fix this, it's abused by scammers a lot.

This scam could have been seen by checking another block explorer, or probably your own wallet too. I'm pretty sure this one didn't show up in your own wallet yet.
Satoshi recommends to wait for 6 confirmations before trusting a transaction. Unless you're dealing with very high amounts, I'd take 1 confirmation as enough.

The important part here is to keep the address "cold".

I've done this before:
1. Download Knoppix
2. Burn it onto a DVD
3. Reboot your computer from that DVD, unplug your internet, close your curtains
4. Start Electrum, import your private key, sign your message
5. DO NOT go online, write down the message, print it, or save it to a USB-stick
6. Turn off your computer, Knoppix runs entirely from memory, turning it off wipes it completely.

I don't think this is possible for the exchange: different order pairs run separate from each other. If they would set it up like this, I think (read: this is based on my current understanding, although I'm not entirely sure) it could be possible both orders are triggered at exactly the same time, and you end up $1000 negative.
