24261  Bitcoin / Bitcoin Technical Support / Re: hola my friends , need some help with a selling and transfer problems on: December 26, 2017, 09:18:22 AM
i cant be selling stuff for $13 and only recieve 6 this is crazyness.
At current Bitcoin fees, you simply can't use Bitcoin for small sales or purchases anymore.
If you would use your own wallet (such as Electrum) instead of Bitpay, and someone pays you 0.001BTC, you'll just see 0.001BTC appear in your wallet. But if you want to use that 0.001BTC by yourself, you'll need to pay a fee again. Bitpay instantly takes the difference, but in the end you'd have to pay it one way or another.
At the way fees are going, you're lucky if you still get $6 out of $13, if fees get higher again (like they were last week), your $13 disappears completely.

As a merchant, you have a few options:
-Pay the fees by yourself (which is what you're currently doing)
-Charge the customer extra when he pays with Bitcoin (which means the customer pays $13 to you, $7 for his own fee, and $7 for Bitpay's fee. This is what my food website did, so I had to stop using Bitcoin)
-Stop accepting Bitcoin (while many people speculate Amazon and McDonald's are going to accept Bitcoin, Steam stopped accepting it).

As much as I hate saying it: Bitcoin is useless for small payments now.

Bitcoin addresses can only be tracked through other addresses. https://www.walletexplorer.com/ is your best shot to start searching.

You could make a post in Scam Accusations with more details about the exchanger.
24263  Economy / Economics / Re: What month 2018 will bitcoin price increase by eight times, just like Nov. 2013? on: December 25, 2017, 10:07:54 PM
If the prices increase by 8x once more, then the exchange rates will be close to $120,000 per coin, and the market cap will be around $3 trillion. Is that even possible?
I'm pretty sure there is no hard upper limit. In other words: it's possible, especially in a hype.
I do worry about sustaining it though! Currently, Bitcoin has only 12 million addresses holding more than 0.001BTC. Anything less isn't worth the fee to spend it. Most people use at least a few addresses, so that leaves at most a few million Bitcoin holders/users.
Miners take about $30-40 million per day in block reward and fees. That's money leaving the Bitcoin ecosystem. The trade volume is about $10 billion per day. Even at 0.25% fee on exchanges, the exchanges take $25 million per day.
Miners and exchanges together take about $60 million per day out of Bitcoin! Divide that by a few million users, and it's (give or take) $10 per person per day. That's $300 per month, and that money has to come from somewhere.
This $300 per user is a substantial drain of funds that enter Bitcoin and are taken out again, and it has to be a continuous supply just to sustain the current price and trade volume.
A price increase needs an even bigger inflow of money. To sustain this, Bitcoin needs more users, but blocks are too full already.
If Bitcoin were to double (or more), miners and exchanges take a larger share too, so even more money is needed to sustain that price level.

Note that this $300 per month is an estimate, it doesn't really matter if it's $100 or $1000, my point is still the same: a continuous inflow of dollars is needed to sustain Bitcoin.
The total for all cryptocurrencies is even bigger: miners and exchanges take their share there too.

i hear rumors that the Segiwt2x fork is going to launch this week.
As far as I know, that's a fake SegWit2x fork, aka a scam.

How many users are in the BYTEBALL database now, if we proceed from this message: "The remaining 1% will be given away to the first 100m users who install Byteball wallet, 100 Kbytes to each user"? After all, we can already sum up the existence of this product.
It's $0.06 per wallet at current price. I don't know how Tony plans to do this, but I expect many people to start farming many wallets if there's no restriction. I alone already have at least 7 different wallets (most used for testing), and this was without trying to farm 100 kbyte.

what are this text coins?
none of them work for me
Text coins make it possible to send coins by email/Whatsapp/anything. If they're posted in public, it's first come first serve. So someone else used them. I'll PM you some.

Why does Bitcoin Core rewrite large parts of the chainstate after startup?
It checks some older blocks, without knowing all technical details I can tell it's to ensure it's on the right chain.

Quote
It happens even when very few new blocks were downloaded, and it takes a long while, sometimes 30 minutes (on HDD).
Is your computer very limited on RAM? It used to take about 1 minute with chainstate on my hdd, and it's reduced to just seconds with chainstate on my SSD.

Your nickname looks familiar, haven't we discussed Bitcoin Core's performance before?
Edit: we did. I still think your performance problems must be related to your computer (hardware or operating system).
24266  Bitcoin / Electrum / Re: Can't access or send the correct amount of BTC from my Electrum wallet... on: December 25, 2017, 09:32:37 AM
ViaBTC still works, but fills up in a few seconds every hour.

If you can manually go through your inputs, you can select which ones are worth using at current fees, but I don't think Electrum allows this. If you want to go full Bitcoin Core, you can import your private keys, download the full blockchain, enable coin control features, and go from there.
I would just wait it out until fees are much lower again. Fees already dropped 85% from the peak last week, if it's low enough you can consolidate your small inputs without paying $400 on fees.

I can't emphasize enough how important it is to consolidate small inputs when you can, instead of keeping them pile up until they're worthless due to high fees.
24267  Bitcoin / Bitcoin Technical Support / Re: How to export decrypted private key from Bitcoin wallet app? wil give you tip on: December 25, 2017, 09:24:34 AM
There's this guide, but it seems to only let you export encrypted private keys, and doesn't show how to actually read them.
Don't you just have the 12 word seed, which you can use (offline!) in https://iancoleman.io/bip39/ to get your private keys?
24268  Bitcoin / Bitcoin Technical Support / Re: What means spent in TXid on: December 25, 2017, 09:11:42 AM
U = Unconfirmed (input).
Spent = Used already in a new transaction.

A chain of unconfirmed transactions means it takes longer for the last one to confirm. If they're all your own transactions you can safe on fees if you send one transaction to multiple addresses.
24269  Bitcoin / Bitcoin Technical Support / Re: ViaBTC accelerator: Sorry, your TXID doesn't exist on: December 25, 2017, 09:09:35 AM
ViaBTC says TXID doesn't exist.  Huh
Try to broadcast the transaction again, it depends on your wallet how to do this.
Or copy the raw transaction and broadcast it from https://coinb.in/#broadcast . After this, see if ViaBTC knows it exists now.

I guess I could just post at the top of each of my posts.
I don't know how it could be considered spam since I give them away with each of my legit posts.

OH, you mean a post just to do give away bytes.  Yeah, I think it would be spammy and I would rather keep my posts with content.
So, I will move my giveaways at the top of my posts, because some people thought I was trying to give that specific person the bytes.  heh.
Actually, what I meant is other normal posts with normal content, like this one for example. Adding a link to Byteball there would be offtopic for sure, but it's much better promotion than inside this thread.
I just claimed your 1MBYTE (I can't resist it!), but this doesn't help promoting Byteball at all, because everybody in this thread uses it already. Or maybe it does help promote Byteball, as you have to open your wallet to receive it. Either way, giving it back with this post Cheesy

24271  Bitcoin / Development & Technical Discussion / Re: Why was there no hard cap built in for tx fees? on: December 24, 2017, 06:29:55 PM
0. How do you prevent malicious parties, especially malicious miners from gaming your system with spam attacks to raise the blocksize?  N.b. that a malicious miner with huge hashrate (such as Jihan) has relatively low cost for spam attacks, since any fees for the spam go back to him for blocks he himself mines.
I'm not sure how to stop that, but I doubt it's worse than paying $30 for a small transaction.

Quote
1. What does this even solve?  A blocksize increase increases linearly.  But Bitcoin needs capacity increase by orders of magnitude—I think at least 10000x, to provide adequate room to grow in the next decade or so.  An 8MB or even a 32MB blocksize would promptly fill today, with no room for tomorrow.  If BCH had Bitcoin’s popularity and demand, then BCH would have high fees, too (and if I had cybernetic wings welded into my back...).  The problem as you state it is really one of scaling.  Linear blocksize increase is a non-solution to scaling.
A blocksize increase gives breathing space, until a more permanent solution is in place. 1 MB blocks were sufficient for the first 6 years of Bitcoin, 8 MB blocks would give 8 times more space to grow.
I agree Bitcoin needs exponential scaling, but until that is available, larger blocks would at least make it possible to make transactions again.
Bitcoin.org still says "low processing fees". It's simply not true anymore.

Quote
2. How does your idea solve problems caused by increased blocksize, such as UTXO set growth, increased orphan rate, etc., etc.?  Blocks larger than 4MB would not be safe for the network.  With Segwit’s 4MB block weight limit, we already have the potential to approach that limit.  N.b. for those in the peanut gallery, increased disk use for a growing blockchain is the smallest problem with increased blocksize.
I wish I had all the answers Tongue It just hurts to see the Bitcoin I like being turned into something that I can barely use. I can no longer use it to order food, unless I pay 3 times more due to fees.
Something has to be done, but that "something" takes much too long.

Quote
Most people don’t realize that competition to increase hashrate (thus difficulty) assures Bitcoin’s BFT security.  I noted this above.  If Satoshi would have been the only one mining all these years, what would now stop somebody from spinning up $100k in EC2 nodes, instantly grabbing 99.999999% of the global hashrate (forget a “51% attack”!), and arbitrarily rewriting the blockchain on whim?  To describe only one obvious and easy practical attack vector.
I do realize the difficulty is needed to prevent attacks, but wouldn't Bitcoin be almost as secure with just 10% of the current hash rate?
Note that I don't mean turning off 90% of current hashing power and waiting for them to do a 90% attack, I mean the hypothetical situation in which 90% of current hashing power was never installed.

Quote
We don’t need for miners to consume less energy.  We need for them to consume more.  Part of the beauty of Bitcoin’s design is that the higher the total value of the network, and thus the higher its security needs, the competition and difficulty of mining automatically increases to adjust.  Satoshi’s home PC was an adequate miner when a bitcoin was worth 30¢.
I was speaking from an environmental point of view. The amount of power consumed is immense! If possible, try to get a tour in a power plant that produces "just" 1 GW, it's much more impressive than I can describe. You can actually feel the power.
If you're speaking from a network security point of view, I guess there is no upper limit of how much power you'd want to consume to secure the network.

Quote
Nowadays, anybody who could acquire ($$$) a majority of hashrate could steal a fortune—and worse, disrupt a market worth the current exchange eqivalent of $300+ billions
Thanks to the Bitcoin forks, there are now actually some parties which control enough hash power to disrupt Bitcoin when they switch to Bitcoin Cash. The Cash fork wouldn't have happened if Bitcoin would have had bigger blocks.

Quote
And the long-term solution is to see serious competition in ASIC production.

How many people even realize that something like 70% of all hashpower is from ASICs produced by Bitcoin’s current most dangerous enemy?
You mean the one with the remote shutdown backdoor?

Quote
I want to see stocking-stuffer ASIC toys which can be sold as a mass-market consumer item, and would each give (via a mining pool) about the same microincome as clicking ads on a “faucet” site.  Call that the ARM/Raspberry Pi level of ASIC.  One step up, I want to see ASICs as cheap and readily available as a commodity consumer CPU.  The equivalents of Celeron/i3/i5/i7 ASICS, for casual miners to moderate enthusiasts.  If ten million people each had an average of a measly 500 GH/s, the result would sum to 5 EH/s.  Current global hashrate is about 8.5 EH/s.  Jihan would cry.
Isn't that what Bitcoin Gold is trying to do (in it's own way)? I'm no expert on algorithms, but as far as I understand they switched to something that's more suited to mine on GPU again.
I'd love to see your idea implemented, and it's much closer to what Satoshi originally envisioned. If Bitcoin entirely relies on 10 million people each mining with a small device, each will mine 0.066BTC per year. In my country that's enough for approximately 350W of electricity (excluding the cost of the device itself).
But even if ASICS could be small and cheap for consumers, that also means they're cheap for large miners, who can then centralize them again.
24272  Bitcoin / Bitcoin Technical Support / Re: Can't succesfully broadcast -Bitcoin Core wallet on: December 24, 2017, 05:16:52 PM
Yes that was the only transaction I made the last few days that somehow went through! I have replaced the wallet with the oldest backup I could find and re-scanned it and made a test transaction which is now in the mem pool, so it all seems to work now (allthough core is very unresponsive). And yeah, I'm definitely thankful for the BTC I still have Wink
Now I'm confused: if you restored a very old backup, the change from your recent transaction may not show up in that one (old wallets are non-HD). If the change doesn't show up, you'll find it back in the backup you made before rescanning your wallet.

24273  Bitcoin / Bitcoin Technical Support / Re: Can't succesfully broadcast -Bitcoin Core wallet on: December 24, 2017, 04:19:41 PM
Okay as said before I'm somehow so stressed out and even a little paranoid about this all (even though there isn't even that much in the wallet!) that I can barely think straight...
Take a break, come back tomorrow after Christmas. Your wallet won't change on it's own.

Quote
I have just checked my old banking accounts and it shows that indeed I have sold some btc back in the days and those sales are in alignment with the dates on blockchain.info! My apologies for instantly thinking about being hacked and all ! Still my wallet seems to have many problems, but I am once again re-scanning. Will keep you updated, and thank you so much for the help so far!!!
I can't tell what's going on in your wallet, but by now I'd say export your private keys and import them into Electrum. After your break that is, you'll need to be able to think straight when you're handling private keys.

Cool Cheesy I'll pick $199 + $2 fee if that is at all possible, just to make sure it confirms eventually.

24275  Bitcoin / Bitcoin Technical Support / Re: Can't succesfully broadcast -Bitcoin Core wallet on: December 24, 2017, 03:50:46 PM
The -zapwallettxes completely removed everything.
Earlier you said: "One transaction (to coinbase) actually did go through". What happened to this transaction after -zapwallettxes?

Quote
*edit... OK with the backup it shows the old value again (my heart is still racing tbh!:)  ) , but what could have happened?
It's hard to say... Can you check which addresses hold funds according to your Bitcoin Core, and see if they actually have funds on blockchain.info's block explorer?

Quote
I do remember that it used to be a wallet without a password (I dont think it had the option back in 2011) and then somewhere in 2013 I used QT to put a password on it. It said something about that it would make a new one and I would not be able to use the old one anymore.
The old wallet unencrypted would still hold all old used private keys, but any new transaction to a new address would no longer be available in the old backup.

Quote
(currently I think I am using the new one).  Could it have something to do with that?
Considering the number of people with similar problems with old wallets, I'm very curious what could have caused this.
24276  Bitcoin / Bitcoin Technical Support / Re: Negative wallet balance on Bitfinex on: December 24, 2017, 01:46:31 PM
HOW CAN IT EVER BE that you start with 3 dollar, you see the next mornig that you have lost that 3 dollar because a flashcrash, PLUS the broker (Bitfinex) comes up that next morning with a 'fine' of 1000 dollar??
You took a loan to gamble, and lost!

Quote
Oke it is MY fault.But I never kwew that you can get a negative margin wallet (880 dollar!)
This will depend on their terms. I don't use Bitfinex (or margin trading in general), so I never read them. But it's quite easy to find:
Quote
You acknowledge and agree: ~; to be responsible for any negative balance in your account(s) on the Site;

Quote
Is this allowed anyway?I have read now (too late, also my fault) a lot about this but I still dont understand it when I read the policies of Bitfinex.
I assume they made you agree to the policies when you opened your account. You should never agree to anything you don't fully understand.

Quote
lost thousands of dollars that I urned of months of trading, but that is simply the risk.To trade again, I accidentally sent 400 dollar of my last money that I can afford to trade to that negative margin wallet (880 negative become now 480 dollar negative), so I'm not able to trade anymore the coming months.And when I ever can afford again a few hunderd dollar, I first have to solve the remaining negative balance(+/- 480 dollar) before I'm allowed to trade by them again.
This is where KYC comes in handy: they know who you are, and can come after you to get their money. Many people join crypto for quick profits only, but large profits come with large risks. Crypto markets are heavily manipulated by whales, with only one reason: to get your money.

I don't think this is the right board, you can move it to Trading Discussion.
24277  Bitcoin / Bitcoin Technical Support / Re: Can't succesfully broadcast -Bitcoin Core wallet on: December 24, 2017, 01:32:34 PM
one of your inputs probably invalid
In this case a rescan can help.

Thank you! Im stressing out over this so I have probably lost some iq points over here.
When all else fails you can always export all private keys and import them somewhere else, but Bitcoin Core should be able to do this on it's own.

Also I now see some older transactions which I was certain I had abandoned, their status has changed to : "conflicted with a transaction with 311 confirmations".
I'm pretty sure your wallet is messed up.

If I may suggest, backup your wallet for safety reasons then do rescan
Close Bitcoin Core, start it from a console with flag -rescan. Or to be sure, you could use -zapwallettxes to also get rid of any unconfirmed transactions you may have.

Quote
if it turned out the same, I think your wallet has forked chain... lets wait for what HCP or LoyceV says about this
I higly doubt it. Click Help > check Current number of blocks. Mine is at 500835 now.

Thank you again! (I couldnt respond to your pm because I can only send 1 per hour). Yes 1Nord.. is the adress I used a lot back in the days. It is a very old wallet from 2011, and haven't used it after 2013 until 3 days ago.
I've never had such an old wallet by myself, but I often read people have problems when they use an old wallet on a new client. I hope you have original ("untouched") backups, in case you need them.

Quote
BTW If I check all the addresses on blockchain,info and compare it to the balance with the wallet, there is a rather big difference. Perhaps this info helps too Smiley I'm currently re-scanning by adding the -rescan tag to the qt shortcut, but it has been on 1% for a while.
Although blockchain.info has it's problems, I trust the confirmed transactions they show are correct.
A full rescan from my hdd takes a couple of hours.

Do you think the btc is likely to be gone and unusable??
If you spent them in 2013, they're gone now.

thanks guys ive contacted bittrex to find out how to export my private key from my BCC wallet
It's not your wallet, it's Bittrex's wallet. That means you can't export that private key, only Bittrex can do that. But they won't.
A solution would be if they offer you to buy the private key to their deposit address at a fee, so you can recover any funds on your own. I haven't seen a single exchange that offers this though, so maybe it's not as easy as I think it is.

Good luck on your quest, post back here if you managed to recover your 0.09!
