I'm looking for a website that gives me the Bitcoin price for any date, in such a way that it can't be debated.
Usage: I want to make a prediction contest, in which the price on November 1 at a certain time(zone) has to be predicted.

Coinbase allows me to export data, but it can be debated. If I compare the CSV for 1w to 3m, it is inconsistent: at the same time and date, the price can vary slightly.

Bitcoinaverage has a graph that I can read the price from, but it uses my local time zone, and depending on how far I zoom in, it gives a slightly different price again.

What website can produce this? I know there is of course no "exact" Bitcoin price, but as long as the site gives a clear answer and nobody can influence it directly, it's fine by me.


No spam
All my threads are now self-moderated to stop signature spam. I will remove all irrelevant posts. If you quote the entire OP, your entry will be deleted.

That's what they all say. Any proof?

Lol.

Give me one reason why they can't use an exchange.

Many scammers used websites similar to bitmixer's domain to lure people. They advertised on Google to trick people into using the fake website.
Since bitmixer closed, they're all popping up with different names now. On the one hand mixing is big business, bitmixer mixed more than a million coins last year, just 1% fee means they earned millions of dollars, so it's  an attractive market for new players to enter. On the other hand, they'll need to work hard on being trusted. Any Newbie who asks for a 0.01 BTC loan instantly gets red trust, but any mixer saying you can deposit 25 BTC can just do so.

The last mixer I criticized claims to own 2000 Bitcoin, but refuses to sign a message. Let me try here too: please sign this message:
If you send this by PM, I will publicly confirm the amount you signed from, without disclosing the address.

From how much to how much?

October 29: I never received any reply from MIXER.TO. They haven't even been online again after October 8.

I wouldn't be surprised if Bitcoin Gold's snapshot has already been taken (and they're premining now). That means you could be too late if you still hve to move your Bitcoins to an address for which you control the private key. But this is just speculation, caused by the lack of information from the Bitcoin Gold team.

Before you import your private keys into a new wallet, make sure you move your Bitcoins to a new address first, for safety reasons.

My strategy is simple: don't care too much

Think of it this way: first, there was Bitcoin. Then, people felt they "missed the train" to get it cheap, so they created altcoins. They hype their altcoin, make it go up in value 1000x, and sell it. That wasn't enough, so the newer altcoins used a premine: 5%, 10%, or even 90%. They earned a lot, until people started complaining about the premines and calling it shitcoins. Then, they created ICOs: instead of just premining and keeping it for themselves, they don't even create coins anymore, it's now "tokens" based on some other coin. The creator starts with not 5, not 10, not 90 but a full 100% of everything! And you can buy them. Take a moment to remember what you're buying: you're buying tokens created out of thin air with some unclear promise on future needs from a few unknown guys. I read ICOs earned $1.7 billion this year alone, it's the biggest hype in crypto ever! It's a great business model: earn money, forget about it, create the next ICO!
Now back to Bitcoin forks: it's the logical next step from people who want a quick buck: create something you have an advantage with, and convince people to buy it.

Bitcoin Gold seems even less trustworthy than the rushed Bitcoin Cash fork. There's not much information about it, but there's only one reason to create any altcoin: make a PROFIT! I've read speculation about it, and wouldn't be surprised if it's true: the creators already took a snapshot, and have been premining ever since. When they finally announce their official fork, they'll be loaded in altcoins to sell off to anybody who buys them.

On a proper Operating System, user directories shouldn't be able to touch eachother.
I don't trust many wallets, and keep most wallets in their own Virtual Machine. If you have enough disk space to add another full blockchain, and have some RAM to spare, I recommend to use VirtualBox for all (untrusted) altcoin wallets.

Roadmap:
And there's the problem: what good does trading crypto do you, if you can't transfer to and from your local bank? Because there's no doubt the government can close that connection.

Can you add an estimate of the value of each airdrop? I like airdrops, but I find it hard to keep up reading so many threads to see which ones are worth anything.

You can't "close" an address. When you put it like this, it sounds like you're talking about a bank account.
Just ignore the addresses you don't use, they don't influence the address you choose.

What you're proposing just gives a higher work load for forum moderators, if they have to check hundreds of threads on complience.
Wouldn't it be easier to require them to buy advertising on the forum? That way Bitcointalk actually benefits from the many ICO-threads, while it proves dedication to their project. And since likely scams aren't allowed to advertise, they're instantly filtered out.

ICO-websites all look the same nowadays, as if it's the same team pulling the same trick over and over again.

They don't care: new account, new name, new shitcoin with scamICO. They can do this over and over again.

Although this increases the chance of the airdrop actually happening, it doesn't turn a scamtoken into a real token. I for one wouldn't want to manage any campaign I don't believe in by myself.

Most of the day, I couldn't access Bitcointalk (like yesterday). But when I check http://downforeveryoneorjustme.com/bitcointalk.org, it says "It's just you. bitcointalk.org is up.".
Does that mean the DDOS cuts off traffic from certain geographical areas only?

When someone pays frequently, you wouldn't forget to inform him about his new deposit address, so I see no problem there.
When someone pays infrequently, and after 2 years just decides to make another payment without confirming the address with you, that's just dumb
Personally, I don't need it. Although I don't follow Satoshi's advice to never delete a wallet to the letter, the only way for someone to ever re-use an address I don't use anymore, is if he randomly finds an old used address on the blockchain and deposits to me. I doubt that will ever happen.

The article is quite technical, but while quickly scanning through it, the word "expiration" isn't mentioned even once. This one does:
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-September/015112.html

Yes you can. See How to read/parse blockchain and get bitcoin addresses having balance. for software that can do this.
But you'll need to download the full blockchain, and have quite a lot of RAM to run it. It might help if you say what you're trying to accomplish.

Much easier: use an older snapshot. Bitcore took a snapshot on April 23 this year. If you download the 140 MB .rar-file you have a list of all addresses holding 0.01 BTC or more on that date.

Lower case L isn't possible. That leaves these options, pick one:
Address: 1PauL5ig66XNwW1LGcbvrJBPv96SaGNKj4 (Balance: )
PrivkeyPart: 5K473hPryYjzccmqJ96HvE6c71wKPPkAxJpys6iUvHdoehJk86m

Address: 1PPSM1zNStmq6bSjPyCpSPFD9e3cvovX7e (Balance: )
PrivkeyPart: 5Kb9G1GvsNTBq9kDKo7wSMhU3iL6EgkQzJSEgc6GQABWv6BhDH7

Address: 1PAUL5NPPAHtvjRHmx8Y1ScRiA2Xwmuba8 (Balance: )
PrivkeyPart: 5KBguTwTy9tXkz58heTCXJYxFKkYqZVUj9UiVtRAdYy9i5PqHVU

You can also use more than one, but if one would get compromised, they all are.

Play around on Google a bit. Example:
I found a long thread in your history, your post pops up on this search.

Are you this worried to go a day without signature campaign?

You're looking at this from the wrong perspective. First, don't post crap. If you have decent posts, you can pick a campaign that will run long. I've been in my first signature campaign until the site closed, for about 18 months. Even though it didn't pay as good anymore at the end, I liked the site, which is worth a lot too.
When the site closed and the campaign ended, I took a few weeks to find a new campaign. No rush.

Let's put it this way: if you get rejected a lot, you shouldn't be in any signature campaign. Maybe that could be a new rule
I take pride of being in a campaign who's manager rejects shitposting. My former campaign even offered a reward if you'd report spam to him.

Agreed. My (our ) campaign manager easily takes 2 days to select 2 out of 20 applicants. This way he can cherry pick the best possible candidate.

I disagree! And this is coming from someone who hates spam. The reason: this will also take away any chance to create a thread from a knowledgeable person who doesn't spam the forum, while those are the people who create true value by posting.
You can't expect him to first spam enough posts to be Jr. Member before being able to open a real thread. I know these are a minority, but discouraging them takes away the last chance to get decent posters.

Deleting entire threads is a much better solution. It seems this happens more often recently, as I've seen many recent threads from people complaining their post count went down. Assuming their signature campaign pays based on the total number of posts, that hurts them financially.
Sure, they'll open another thread, but if a moderator can trash 2000 posts with one click, I'd say it's an easy solution.

A much better solution is of course stricter rules for signature campaigns. I recently checked the post history of a few people enrolled in a certain signature campaign, and most of them were posting in Spam Megathreads^*. This is just a small example, in my opinion they should all be deleted:

^* I'm not sure who came up with this term, I saw it first used by DarkStar_

That's what I expected indeed.

Pages have barely been loading for me since today only, the rest of the week it worked fine.
Now it varies from "performing a TLS handshake" to "busy try again (504)". And in between I can post.

I had to search the meaning of the word Reflation. Wiki:
While the European Central Bank largely increases the money supply, our national government (the Netherlands) has raised several taxes and increased the government's spending as a share of GDP since 2008. They also increased VAT, which further increases inflation. So they're doing one thing according to Wiki's definition, and the exact opposite on the other thing.

As a family with some savings, we don't need inflation. ECB is still printing enough money to slowly inflate away savings, banks give very low interests, taxes on savings alone are 5 to 30 times higher than the interest the bank pays. We don't have a capital gain tax, which is very beneficial if you're rich and own a lot of assets, but the common man sees his savings slowly evaporate.

This leads to the poor being okay, the rich being okay, and the middle class paying the bills.

I like reading BobK71's point of view, but indeed, it barely pops up without actively searching for his posts.

So what can we do to change this? I see this happen around me indeed. The low savings interest, high tax, and increasing inflation forces people towards risky investments with money they can't afford to lose.
The one difference we have in recent times, is much more free information. But most people (me included) don't get much further than watching the occasional documentary about it, agreeing to what I just watched, and going on with my life because I can't change it.

Social security is meant to keep people in line: give them enough not to protest, and enough to keep make them depend on the system so they don't attack the system.

For months now, you literally only post in Byteball-threads, and you only complain about it. May I ask why? If you don't like it, that's totally fine, leave it and forget about it.
What's in it for you to keep telling over and over again how you don't like Byteball?

So you're only complaining because your free Bytes went down in value?
