I think that the options are too rigid. Nobody wants all those graphs together.
I think that you should take a look at cryptrader (I don't know how good it still works, but the graphs are there). There the user can select the exact (exchange and) pairs he wants to see, plus other useful options like depth or order book.
9724  Other / Beginners & Help / Re: What sets the price of Bitcoin? on: December 23, 2019, 08:21:53 AM
The exchanges purchase a bulk lots of Bitcoin that they can sell on there exchange, or do they have a list of traders/wallets willing to sell that they transact with when I click the buy button?

There are multiple types of exchanges.

The biggest exchanges are simply platforms to connect users. They don't store anything. Some users will put some asking prices. If the prices are unrealistically big, they will not sell, because others will sell on smaller prices. Some other users will want to buy. If they offer too low prices, nobody will want to sell to them, since others will want to buy at higher prices. When seller and buyer prices match, the sale is done and the platform will get a small fee.

On these exchanges you can also sell/buy "instantly". In that case you'll match the highest buyer's price or the lowest seller's price plus the platform fee.

There are also exchanges where you can "trade" directly with the exchange, not other people. They have bigger fees and how they work is their business. They keep a stash, but I think that most have it small and have some money waiting on some of the biggest exchanges and when you initiate a trade, their bots will also make a similar trade on the "normal exchanges" to replenish the stash.

Do the miners somehow set a 'reserve' price at which they are willing to sell, or is the price of one BitCoin defined somewhere else by someone else?

Any trader tries to sell.buy at a price - bigger or smaller. They don't necessarily trade at the current spot price, they may wait the price rise (if they sell) or fall (if they buy). Maybe you should read about limit sell and stop loss.
I said traders. Not only miners trade.

How do the various exchanges determine the price? Whats to stop one exchange selling at $5000 and another for $3000? How do they synchronise their pricing and why do they differ slightly?[/li][/list]

The price is determined as I wrote, by the buyers and sellers expectations.
Also there are plenty of trading bots, some are arbitrage bots which will "equalize" the price between exchanges as soon as one has much different price than the others (by buying from one and selling to another).
9725  Bitcoin / Electrum / Re: electrum - watch only - how to use? on: December 23, 2019, 07:55:48 AM
A watch only wallet is something you create without seed or private keys. So you cannot spend. One great use is to build transactions which you'll sign later with the cold wallet.
A watch only wallet can be created with the address or the master public key. Tutorials are here: https://bitcoinelectrum.com/creating-a-watch-only-wallet/
The watch only wallet has no info at all about the private keys.

When you'll have the private key or seed, you'll just import into a new wallet. If it's a private key instead of seed, you'll go this path: https://bitcoinelectrum.com/importing-your-private-keys-into-electrum/
(I have the feeling that you went this path already and instead of pasting there a private key, you pasted the address)

About the creation date, I don't think you have that. Maybe the file date can help though.

Do you mean about his comment on twitter saying he will eat his D on television if his price prediction didn't come true?

Yep, that's the one. I clearly hope his prediction comes true, but realistically I think it won't. And then it should be interesting (if he keeps his promise, of course).

Are you using some tools to make this work?
How did you manage to make it work?

From what I know this works https://api.blockcypher.com/v1/btc/main/addrs/1BitcoinEaterAddressDontSendf59kuE?after=520000&before=550000
But you have to test/make sure it works for you (afaik it returns only a max number of tx) and you have to know the block numbers for the period.
9728  Economy / Gambling discussion / Re: two gambling games that are players favorite on: December 22, 2019, 06:19:00 PM
There are two games gamblers like this are card games and dice games ive seen people who look for this games everywhere , because this games are easy to learn and dont need too much effort how to do it, at the same time there is a bit high chance to win, aside from other games do you agree with me, feel free to share ypur opinion thanks

No. There's roulette, there are the slots, both easier than cards and many users love them. And there may be others I don't remember now.
Also don't forget those who got bored by the "old fashion" games and want to try out something new.

especially in card games like poker that it always gives me a thrill whenever i play it at the casino

Card games (and here Poker is a top choice) are - for many - much more interesting when playing face to face with people and in many cases even with people they know (!).
They can be an option in offline casinos, but in many cases not so interesting online.

9730  Bitcoin / Bitcoin Discussion / Re: Bitcoin Halving Block Reward Countdown on: December 22, 2019, 06:00:22 PM
May be you need little adjustment?

The halving will happen at a certain block (630000), we know that. The actual date/time.. is harder to calculate.
The date/time is estimated based on current block and the average block time.

Let's see..
Current block is 609,325
Blocks to go 20675
Average time 10 min
This gives ~143.5 days to go.

Now... if the block time is estimated in different way, the result can differ.
Since the difficulty adjustments were mostly upwards, shorter average block times are a good move.
I think that maybe OP took into account shorter period for these adjustments and according to the graphs in the last month the adjustments were staying under the value from Nov 25. Is this a new trend? I doubt it. And maybe here's where OP could adjust his algorithm. Or maybe he's right and he knows something I don't expect.

Too late the damage is done.

Indeed, the damage is done. But I think that the move will revive a little that exchange.
It's something I was expecting (hoping?!) with their move to Seychelles.
Although it's indeed a shady location which could cause other problems, let's be at least a bit optimistic.

If nothing else works, another idea could be to make a symlink with the name Bitcoin expects and which points wherever you want.

9734  Other / Beginners & Help / Re: Can someone post examples of unusual transactions to help me understand.. on: December 20, 2019, 10:56:39 AM
Unconfirmed transactions after many days of the payment (does this even happen)?

Normally a transaction not confirmed after 2 weeks is dropped from the mempool.
Since lately there was no huge congestion, afaik there are not so old transactions to show.
https://sochain.com/ tells that the oldest transaction in its mempool is 17h old.


A transaction which showed confirmed till 4 or 5 blocks but then was 'reversed'? (if I read right, after 3 confirms this is rare but possible)

Afaik "reversing" a transaction happens only if the block which included the tx got orphaned.
This means that soon enough nobody will have anymore that block, so there will not be any record to show you.
If it helps at all, this statistic shows that there were no orphaned blocks lately (1.5 years).

The only thing I could find myself is here https://tradeblock.com/bitcoin/explorer/ this has the feature 'Conflicting transactions'. Some are from very old blocks e.g. from 2015:
https://tradeblock.com/bitcoin/txout/e276d10865d7780f2ef6436cfe49874131a53ad4199df7c7ee47cd883c29ac5b/0
What are these? Double spend scams?

Most probably double spends. Scam or mistake.
Such a conflict occurs if at least one input is no longer available, afaik.

What is more absurd is that cryptotalk signature barely have a design. It is mostly composed by big letters without any art, just with fancy colors.

He could at least change the colors, nobody would accuse him,.

Actually it's not absurd. I think that the user intention is that others click his link by mistake and get some traffic to his website.
Quite childish behavior, however...

9739  Economy / Web Wallets / Re: Blockchain info not displaying balance on: December 18, 2019, 03:23:03 PM
I created another wallet on blockchain info wallet and it works fine though. I put my 12 word seed in electrum to restore the wallet there but its been synchronising for 5 minutes. If that works does that mean I can access my coins on my blockchain info wallet ( if it works again ) and on electrum at the same time?

I keep telling the same all over again: you coins are not in the wallet, they're on the network; the wallet (usually) handles the keys.
This means that you (and others!) can have many instances so the wallet. Whoever has the keys can spend (so don't just fool around with that seed, since if you have malicious software on your computer/laptop somebody may steal your coins; write down the seed and keep it safe).

So yes, you can spend from blockchain.com or electrum.
(I hope that you have a clean / correct Electrum from electrum.org)
9740  Bitcoin / Project Development / Re: All Bitcoin Addresses With Balance on: December 18, 2019, 03:12:08 PM
There used to be such lists available here and there, but most are outdated, not available or simply not for free.

I've found a post with links to tools that may give you what you want, although they may need adaptations (and the chain data!), the may not work with pure SegWit addresses and so on. If you have the skills and the wallet with the blockchain, this is a good direction.

There are also sites like https://bitkeys.work/ where you can find all the addresses with balance, for free, but they're in web page you have to check page by page.


PS. The most usual use for such lists is to attempt whatever brute force. If you want to do that, please read more, since it's a task that will waste energy with no results.
