24101  Bitcoin / Bitcoin Technical Support / Re: accidentally transferred BTC to BCH not credited on: January 11, 2018, 10:28:41 AM
I have accidentally transferred BTC from bitconnect BTC wallet to Dekado BCH wallet. Hence it’s not credited in destination wallet. Bitconnect BTC wallet is deducted but neither Dekado BCH wallet or any other wallet is credited against this transaction. How to recover BTC?
Although I've never heard of "Dekado wallet", the procedure is the same as any other wallet: you'll need to export your private key to that address, and import it into a Bitcoin wallet (for example Electrum).
24102  Bitcoin / Bitcoin Technical Support / Re: 0.016 BTC stuck in Blockchain.info wallet (offering 15% to anyone who can help) on: January 11, 2018, 10:20:43 AM
We have 0.0163 BTC stuck in Blockchain.info wallet.
I assume you have many small inputs, is that correct? Fees aren't that high at the moment, so it might be possible. But if your inputs are smaller than 0.0004BTC, they'll be eaten by fees entirely if you want a transaction with any chance to confirm within a day.

Quote
We can offer 15% (0.0025 BTC) to anyone who can help us take these funds out and send them to that address.
I'd be happy to help you, but only the person with the private key can make the actual transaction.
Do you have different sending addresses (aka different private keys to export), or just one? Either way, can you share those addresses?

BitcoindException(super=com.neemre.btcdcli4j.core.BitcoindException: Error #-26: 66: mempool min fee not met, code=-26)
Your Bitcoin dusts isn't worth the fee required to send it. What I would do, is export the private keys, and make a low-fee transaction from another wallet. It may take weeks to confirm, or it may even be dropped from mempool again. If that happens, just keep your 0.0163 BTC and wait for fees to drop somewhere in the future.

If not just export private key to other wallet.

I'd use Electrum (upgrade first), it's the most common wallet, or Bitcoin Core if you have it installed already.
24103  Bitcoin / Development & Technical Discussion / Re: How to do micro payments with bitcoin? on: January 11, 2018, 10:04:25 AM
"I don't think the threshold should ever be 0.  We should always allow at least some free transactions." Satoshi Nakamoto.
I can sympathize with Satoshi's sentiment there, but he didn't build incentives for that into Bitcoin's design. The system relies on rational mining incentive: miners publish transactions because they are incentivized to mine for block rewards and collect the fees.
As far as I can tell, Satoshi never intended the current situation to happen. Back in 2010, he already suggested to phase in bigger blocks again, but this never happened.
When Satoshi created Bitcoin, there was no difference between nodes and miners: before asics took over, all nodes could mine. Miners currently earn around $30 million per day from block rewards and fees. I can only imagine how decentralized Bitcoin would be if millions of users could all run mining nodes on their own home computer, and all earn a few dollars per day from this.

Quote
It's the mining incentive -- and therefore the protocol itself -- which resulted in this situation. This is the only way the system can guarantee block rewards in the future, once most of the 21 million coin supply is mined.
I don't disagree with the fee-replaces-block-reward thing, but in my opinion it's too early for that. It would be perfectly fine 20 years from now, when Bitcoin has a billion users who each make several transactions per day. Now 300,000 users pay around $7 million in fees per day, which limits adoption to the point that services that were accepting Bitcoin in the past, are now abandoning Bitcoin.

The BCash guys are literally hanging on with their finger tips. They know the Lightning Network and SegWit will eventually render BCash obsolete, but they are using this temporary advantage in their favour, to push BCash adoption and to attack Bitcoin's current scaling problems.
All true, but none of these forks would have happened if Bitcoin would have allowed more transactions years ago, long before it became a problem, and long before any miner would reject an update to Bitcoin Core that makes this possible.

Quote
This was a stronger attempt, but Bitcoin is known for coming back in the last rounds. ^smile^
I really hope so.

Quote
Cheap micro payments with Bitcoin <Lightning Network> has been done on the Main Net, but it is still early days for this technology.
It's a very complicated solution that needs time we don't have. Larger blocks could have offered temporary relief for the network. Instead, we got RBF and CPFP to pay more for a problem that shouldn't have existed in the first place.

I don't like Bitcoin Cash and especially the manipulation from the guys behind it, but I can't deny it works just fine to send a transaction.
24104  Bitcoin / Bitcoin Technical Support / Re: Stuck transaction (185 satoshi per byte) for two days on: January 11, 2018, 07:11:30 AM
Two days ago I sent the following transaction: 6f917d372316dead7ada76fdc7f2f854c7344df7d31c8a7bd6e454ede1110806
Your problem is this unconfirmed input with 50 satoshi/byte, that transaction will have to confirm first.

Quote
I used the "economic fee" of 185 satoshi per byte (amounting for 5$ for an approx 50$ transaction).
I've seen lower fees than that get confirmed in the past hours, but your input's fee is still far too low.

Quote
Is there extreme traffic on the network at the moment?
There is, and has been for quite a while now.

I tried the first accelerator and I receive the message that "submissions are beyond limit". How could I find the right spot to submit? By trial and error?
I like to say "impeccable timing", it resets every whole hour, and you have at best a few seconds to enter your transaction. But you'll need to enter your unconfirmed input first.

Quote
As for the second, it asks for my mobile number, which I am not comfortable giving. Is there any other (free) way to push this forward?
ViaBTC is the best I've found. I've tried Antpool (just get a cheap prepaid simcard), but so far I can't say with certainty it ever worked for me.
24105  Bitcoin / Bitcoin Technical Support / Re: Can Bitcoin be fixed? on: January 11, 2018, 06:57:00 AM
You can make bitcoin transactions about 20-70% cheaper just by using segwit adresses.
Since I joined Bitcoin, fees (in dollar) went up about 1,000,000%. Just 8 months ago, this topic was opened: $0.85 transaction fee is absolutely ridiculous!, and since then I've seen "normal" fees peak around $30 for a small transaction.

Quote
and companies/exchanges adding way too much fees to their transactions.
Users are bidding against eachother for scarce block space. The net-result for users is we pay more and still wait, the net-result for miners is they earn $5-10 million per day extra, and the sad result for Bitcoin is it can't grow when we can't use it.
I've seen Bittrex pay $5000+ to store 32 kB on the blockchain.

I still have hope Bitcoin can be fixed, but the dropping market share isn't good. Once people use something else, it's hard to get them back.

An HD-wallet, such as Electrum or Bitcoin Core, can do this. But the wallets won't share your address book (and transaction descriptions), and you double the risk of losing your coins.
Depending on the amount you want to keep in your wallet, you could consider using different wallets on both locations.


You're posting this question on the wrong board though, you can move (bottom-left) it to either Beginners & Help or for more in-debt questions Bitcoin Technical Support
A better title helps too, for instance: "Can I use one wallet on 2 computers" describes your question much better.

The whole point of decentralized cryptocurrencies is getting away from big established institutions, and yet, the entire crypto-market responds sharply to opinions given by the richest people who benefit most from centralized power.

This is actually huge news. It sounds like he is trying to use decentralization for Facebook. "Giving people the power", as he says.
Zuckerberg used to say he puts the user-experience on #1. Then, he had his IPO, and now the stock holders (including himself) are #1. Paid advertising is probably #2, some other rich corporations #3-8, and the users are somewhere at the bottom around #200.

This is a great news for crypto. I hope Facebook will adopt bitcoin and existing altcoin than creating its own crypto currency. Nevertheless, I am sure more people will be interested in crypto with Facebook support.
If anything, I expect Facebook to compete with Paypal. Think of it like Microsoft using it's market dominance to kill compatition (does anyone even remember Netscape or ICQ?), just like Facebook destroyed other social networks.
If Facebook introduces it's own payment system, it doesn't matter whether or not it'll be decentralized, it will start out with a billion users instantly.

But if he decentralizes facebook, it will be a disaster.
What's with the decentralization hype? Facebook runs on millions of servers, there's nothing there to decentralize.
24112  Economy / Goods / Re: Coin Armor - steel cryptocurrency wallet on: January 10, 2018, 11:23:11 AM
How safe is the wallet if or when released? Obviously, using this wallet would mean trusting the wallet's developer or creator. And, most importantly, being convinced that such wallets are at no risk of being accessed via a backdoor system.

I love the idea of engraving both the public and private keys on the card, protected by a passphrase-protected Bitcoin private key. Is it really secure?
This thread gives a good idea of how strong BIP38 encryption is: I'm BIP38 curious, please help me out!.
In short: password zLwMiR was not cracked in 2 years for a 1 BTC (more than $1000 at the time) prize. It would cost more in computing power than it's worth.

I can think of one scenario to crack it though: suppose a hacker has access to a botnet of a million computers, that would give him enough computing power to crack this password without high cost.
This can of course easily be prevented by using a longer password.

That being said, I'd still have a very hard time trusting anyone with my BIP38 encrypted private key. It feels scary, even though the math says it's okay.
24113  Bitcoin / Bitcoin Technical Support / Re: Beginner question! Please help on: January 10, 2018, 11:14:25 AM
Please bear with me, I'm a complete beginner.
Welcome Smiley

There's some things you need to know: first, stop using GBP to describe amounts of Bitcoin. You sent a certain amount of Bitcoin, the fiat-value of it has nothing to do with it when you send it.
Second, Bitcoin fees have been very high for a while, and it doesn't look like that's going to change any time soon.
Your "5GBP" transaction was likely about 0.0003BTC, with 0.001BTC in fees. Basically, the transaction was smaller than the fee. More and more services are now setting minimum deposit amounts, because they can't send such a small amount anymore (it would cost them more in fees than it's worth).

My advice: don't make small transactions "as a test". I know this is very beginner-unfriendly, when I started using Bitcoin I could just play around with cents to see how it all works, but unfortunately those times are gone.
If you want to start trading, fund your account at once with as much as you're willing to lose. And double check the address before sending.
24114  Bitcoin / Bitcoin Technical Support / Re: Is it possible to refuse/delete a payment we received? on: January 10, 2018, 11:02:36 AM
With 20 sat/byte, and an unconfirmed parent with the same low fee, I expect the transaction to be dropped from mempool eventually.

Anyway this is unconfirmed, and we don't want to find ourselves again sending Bitcoin funds using our wallet and getting them stuck because of this potential "Parent" transaction
I'm not sure how blockchain.info handles this, but I assume you can opt not to use unconfirmed inputs in your own transactions.

Quote
If anyone wants those 0.001 BTC for free by all means come and take them, just let us know how to get rid of this transaction and remove it from our wallet please.
You'll need to hand over your private key to someone in order to "take it". That would give that person access to the remaining 0.00353186 BTC in your wallet too, so don't do this.

If blockchain.info allows you to select the unconfirmed input for a transaction, you can send 0.00002 BTC to 1BitcoinEaterAddressDontSendf59kuE and use the remaining 0.000101632BTC as fee. This way, it doesn't matter if it triggers CPFP and confirms, or the original transaction gets dropped from mempool. One way or another, it'll be gone for you.

24116  Bitcoin / Bitcoin Discussion / Re: Bitcoin Foundation executive director Llew Claasen said this is a bubble on: January 10, 2018, 10:38:46 AM
I think what he means is Bitcoin is rising too much too fast. It would be better for people to buy and hold for a long time and let the price rise slowly. Instead people are buying and selling fast. That will cause a crash.
I prefer to look at BitcoinAverage in log-view:

This graph has been going up steeper than average lately, just like it did before the previous drops. If there is anything you can predict from this graph, I think it's that Bitcoin will go up long-term.

A month ago "everybody" was predicting Bitcoin to go up to $50k, $500k or $1M! Basically, when it goes up, all "predictions" are that it will go up more, and when it goes down a bit, "everybody" says it's a bubble that will crash. And the beauty of all this: they'll all be right at some point in the future! How easy is it to say: "I told you so" if everybody is right at some point? Mark my words, I'll tell you "I told you so" later Cheesy
It's just in Bitcoin's nature to go up and down a lot, and the shitload of altcoins is accelerating this. High fees, miner's electricity bills, exchanges' commission and altcoins/ICOs are all draining money from the Bitcoin ecosystem, and yet, it's worth more than it ever was a month ago!

Of course Bitcoin has been rising too fast, and altcoins even faster. There's not much logic in going up 100x or more in a year.
Who here even knows most ICOs are actually ITOs? They don't even have Coins, they sell Tokens! Altcoins are created with only one goal: earn money for the creator, and Ethereum is the one that enables many other Tokens to be sold at high prices, meanwhile increasing it's own price.

I'm hoping that this bubble does burst so that we can shakeout the greedy investors that Bitcoin has currently groomed.
You'll never get rid of "greedy investors". I don't think many people joined Bitcoin (or this forum) for any other reason than trying to earn some money.

Using Bitcoin to top up my prepaid phone, or to order ebooks online... Those were the glory days.
It pains me to see this isn't possible anymore due to high fees, and I don't believe this can't damage Bitcoin. Bitcoin is designed to be electronic cash, but it's too expensive to use.

Quote
took the opportunity to start hodling and introducing friends and family to BTC
I know several people who are interested in Bitcoin, and would like to buy some, but I can't in good conscience recommend doing so at current fees.
Example: the most popular site to buy/sell Bitcoin in the Netherlands (Bitonic) sells a minimum of 0.01642589BTC for 200 euro. If you would want to sell it again (0.01562589BTC after fee), you get 170.58 euro back. That's an instant 30 euro loss (the site takes a few percent only, the rest is caused by fees). I hate it, but because of this I can't recommend buying small amounts of Bitcoin now.
I can imagine many people keep their coins on an exchange. This saves fees, but you risk everything to do so.
24117  Bitcoin / Bitcoin Technical Support / Re: Need help with 3 unconfirmed tx. There is a small reward on: January 10, 2018, 10:21:20 AM
The third transaction has 2 confirmations already, the other two don't show up on other block explorers. They've most likely expired from most mempools already. Any chance you can just re-send it with a higher fee by now?
24118  Bitcoin / Development & Technical Discussion / Re: How to do micro payments with bitcoin? on: January 10, 2018, 07:10:08 AM
At current fees, you can forget about micro payments. Even if you manage to send a payment at low fee to many addresses, those addresses can't use the Bitcoin dust, as it would require a higher fee than it's worth.
Lightning Network is supposed to solve all this in the future, I just hope it won't take too long.

It seems like you've used Electrum before, and it's trying to open your old wallet. Deleting Electrum and reinstalling it won't help.

It is a bit weird Electrum doesn't give you the option to create a new wallet, if the last wallet you used has a password.
Solution: you can just rename ~/.electrum to ~/.electrum.old and restart Electrum for a fresh start.

Quote
Could it have started to put something in a library folder somewhere that I need to delete to do a new install?
I wouldn't delete your old wallet without remembering what's in there. That's why I suggest to rename it, just in case you remember your password later.
