1081  Bitcoin / Bitcoin Technical Support / Re: guidance on buying first BCT on: November 21, 2017, 02:49:02 AM
Coinbase is my usual recommendation to get started.
Isn't Coinbase similar to having a bank in a way? At that is what I have read. I was more going toward using Mycelium and was
trying to learn the base way to buy my first coin using that.  I'm not sure in what case I need to hire an Escrow. Looking at one example: localbitcoins.com and I think that has a built in Escrow. Not sure if I understanding hiring an escrow and how that would work exactly. Still researching.

Coinbase and localbitcoins are both good ways to buy a bitcoin or fraction thereof. Once you do at Coinbase for example, then you would transfer it out of coinbase to your own wallet such as Bitcoin Core or Electrum or Mycelium (I haven’t used Mycelium myself).  If you left it at coinbase, that might be similar to leaving cash at a bank, yes. 

Coinbase is easiest in my view, although some people aren’t fans.

Well it looks like the following:

- I'm using a Raspberry Pi
- 700 MHz/s
- 512 MB RAM (64 MB reserved for gpu)
- Debian Stretch
- 6 MBit/s Internet Connection
- System and Blockchain running on an USB drive

Is there a problem with the configuration, concerning the slow blockchain download?

Yes. Several.

512MB (-64MB) is very small. 700mhz is very slow.  USB may be slow for lots of io, (maybe not USB 3 or greater), but the others are particularly if Debian is using it for swap etc. And bitcoin for the block chain etc.
1083  Bitcoin / Bitcoin Technical Support / Re: Block size 1 MB on: November 17, 2017, 04:49:33 PM
...
The future is difficult to predict.  Those that are confident about the future are almost always wrong.  It seems unlikely that 1 MB blocks will destroy bitcoin (they've been limited to 1 MB for more than 8 years and it hasn't destroyed it yet), but I guess we'll just have to wait and see.  That's just one of the many reasons that Bitcoin is still considered to be "experimental".

...

My only note on this is small to point out that I believe the 1MB limit was added in 0.3.1 which was released July 2010 so it hasn't been at the 1MB limit for 8 years yet.  I only point this out because DannyHamilton's posts are always a great tool for people wishing to understand bitcoin and may be used as reference so want to ensure that even small things are correct.  ;-)

This sounds like an alt-coin, so you should move it to the appropriate section since it isn’t about bitcoin -they’ll be more likely to know the changes that have been made to the wallet.

You have to do nothing because it was canceled.

One group of miners is still doing it per their public announcements.

When will airdrop begin ?

Right now, it looks like about 9 blocks when it will occur.  So around 1-2 hours.
1087  Bitcoin / Development & Technical Discussion / Re: Questions on 'New Opcodes' to be implemented in elements on: November 16, 2017, 07:49:41 PM
Hi all,

I've been reading through the various element's projects that become a part of the sidechain. I've read through New Opcodes and I was confused about how the two use cases - double-spent protection bonds and probabilistic payments worked.

Doesn't Bitcoin already have considerable protection against double-spends and how are these protection bonds associated to it? Also I wasn't able to determine what probabilitic payments were, At the moment the source code page takes me to a 404 page (https://elementsproject.org/elements/opcodes/elements/opcodes/index.md) which I'm hoping might be resolved soon.

I hope someone which some knowledge on this would be willing to throw some light and help me understand?

This discussion may help with probabilistic payments:
https://bitcointalk.org/index.php?topic=62558.0

It is obviously an old discussion, but it might be helpful in understanding them although I think they have been fleshed out more.
1088  Bitcoin / Press / Re: [2017-11-14] Recovery In Doubt? Bitcoin Price May Not Sustain Above $6,500 on: November 16, 2017, 12:09:44 PM
All this TA stuff is just guessing and certainly isn’t news.  Just click bait articles.


Recovery In Doubt? Bitcoin Price May Not Sustain Above $6,500

Bitcoin is in recovery mode today.

As of writing, the bitcoin-U.S. dollar (BTC/USD) exchange rate is at $6,523, having reached a high of $6,559 so far. As per CoinMarketCap, the cryptocurrency has gained 3.54 percent in the last 24 hours.

Still, chart analysis indicates that BTC has retraced 38.2 percent of the sell-off from Nov. 8 high to Nov. 12 low. That's when prices hit a two-and-a-half week low near $5,500 – a near 30 percent sell-off from last week's record highs.

Largely believed to be triggered by the suspension of the Segwit2x hard fork, a software upgrade that might have brought a transactional boost for the cryptocurrency, investors had reportedly begun moving funds across to bitcoin cash (BCH) following its abandonment, resulting in a rally for the rival cryptocurrency.

In this way, the sharp recovery seen today has been accompanied by an equally sharp pullback for bitcoin cash, which rose more than 30 percent last week, and briefly overtook ethereum as the number two cryptocurrency by total value over the weekend.

Still, it is too early to say that bitcoin prices have found a bottom.

As discussed yesterday, the price chart analysis shows the current pullback could find a bottom around $5,000 levels. The latest chart shows the prices have moved above the key trendline hurdle, but continued gains are less than certain.

Bitcoin chart



The above chart shows:

   - The trendline from the May. 15 low and Oct. 5 low is capping the recovery in BTC.
   - The 5-day MA and 10-day MA adopted a short-term bearish bias last week.
   - The relative strength index remains below 50.00 (in the bearish territory).
   - On the 4-hour time frame, the 50-DMA has adopted a bearish bias, while the 100-MA is moving sideways (neutral).

View

   - A move above 5-day MA of $6,482 is likely to be short-lived.
   - As noted yesterday, BTC is likely to trade sideways in the short-run, before resuming the sell-off and eventually finding a floor around $5,000 levels.
   - Only a close today above $6,900 would signal a revival of the bull market.

1089  Bitcoin / Press / Re: [2017-11-14] When will bitcoin collapse and what stands behind crypto hype on: November 16, 2017, 12:07:56 PM
WHEN WILL BITCOIN COLLAPSE?
There is a widespread opinion often met in the media that crises taking place across the world increase the demand for bitcoin and other cryptocurrencies. Recently there has been some suggestions that confrontation between the US and Korea fueled interest in cryptocurrencies. Is the cryptocurrency market so sensitive to all sorts of political games, and is it true that it’s just a pyramid and that bitcoin will crash soon, Bitnewstoday figures out.

THERE IS TOO MUCH PR-FAKE IN CRYPTO NEWS
The talks about influence of political confrontations on the demand for cryptocurrencies are considered by most experts as a PR-fake. In their opinion, journalists and representatives of crypto startups with such positions just give out desirable for valid.

Considering that the total market capitalization of...Read more

This sounds like a poor Google Translate article.  One would wonder if you can’t even get language correct, why one would rely on their forecasts.

Clearly they have a love hate relationship with it -
But they NEED to adapt to it to keep up with it and ensure that they are able to still maintain their piece of the pie.

Do you think this will change the community that was built on this type of currency?

Any form of "cryptocurrency" coming from a major institutional player will be just another shitcoin and will share the same fate as all other shitcoins...

Agreed.  If there is only one or very few participants in this block chain technology, they can just use a database and a contract with merchants.

1091  Bitcoin / Bitcoin Technical Support / Re: Need help immidiately, bitcoincash got sent to wrong address (STILL UNCONFIRMED) on: November 15, 2017, 11:14:35 PM
im trying to send the money back to my wallet, i want to post a bigger transaction

It already has 18 confirmations so not much you can do.
And I don’t know what this “want to post a bigger transaction” means.

1092  Bitcoin / Bitcoin Technical Support / Re: Need help immidiately, bitcoincash got sent to wrong address (STILL UNCONFIRMED) on: November 15, 2017, 10:07:04 PM
Hey gyuys i know this is a rush but im on 12/20 confirmations nd need to solve this now. Is there anyway i can double spend my bitcoincash transaction with a higher fee and how!


this is the transaction:

https://blockchair.com/bitcoin-cash/transaction/560d47d646b1474d9d98b392864a68bda9519ce257682d8c145a20a1c2f3a0ba

If it has 12 confirmations, it is confirmed.  And looking it has 15 or more now.  Once it had 1 confirmation, it is confirmed.

What exactly were you trying to do?
1093  Bitcoin / Development & Technical Discussion / Re: Is there such a thing as time stamp service? on: November 14, 2017, 08:06:53 PM
How can someone combine a timestamp server with their own personal signature?

I found this online:
https://tsa.safecreative.org/

Then perhaps I create a work of music. I want to timestamp the creation of the music by combining a time stamp hash by 3rd party authority (as above) with my own public and personal key.

I illustrate as such:

hash(music work) + hash (timestamp) + hash (author key) = new hash of copyright proof of date/time creation

the important aspect here is the timestamp service has to be 3rd party.


Is such  thing possible? How to combine it with bitcoin or other coin? Or maybe entirely free (piggy backing on blockchain transaction times)



Perhaps something like this?:

or
https://bitsig.io

"This keeps the amounts transferred visible only to participants in the transaction (and those they designate)" -- ElementsProject.org

I would like to get more info about this, how do you designate someone to be able to see the amount of a transaction? pretty sure private key won't be involved. Also, what more advantages CT gives us, excluding the anonymity.




There was actually more about it on the Developer list this morning:
https://lists.linuxfoundation.org/pipermail/bitcoin-dev/2017-November/015283.html

1095  Bitcoin / Press / Re: [2017-11-13] Why Aren’t There More Women in Bitcoin? on: November 13, 2017, 11:28:31 PM
Gender is about as relevant as eye and hair color when discussing ideas. 

It is very condescending to women to imply that men have to try and get more women involved in Bitcoin. Women are free to become involved or not without having to have men try and encourage it, it is treating women as less capable to imply they need help.  Women don’t need men to hold their hands to get them involved, everyone has the same opportunities. 

What I want to know is the percentage of people who self-identify as female and the percentage that are cis-gender.  Are blue and green eyed people underrepresented too?   /sarcasm

1097  Bitcoin / Bitcoin Technical Support / Re: Timeout on un-confirmed transactions? on: November 13, 2017, 01:26:56 AM
So i have a transaction thats went 24 hours with zero confirmations. it had preference high at 96% confidence. now it looks like its been re-sent but only 42% confidence and preference low. If i never recieve this bitcoin, what happens? It's about $2000 worth.

You should probably start your own thread, but what is the transaction ID?  What wallet was used?

It will either confirm or not so will either remain where it is or go to the new address.  There is no limbo state where bitcoin isn’t somewhere (nothing like a check in the mail) since bitcoin is at a lower level built on inputs and outputs.  If someone was sending it to you, you can keep broadcasting it.  But without the transaction ID, it is difficult to give much concrete information.

Try pasting the address into a text editor to ensure that there are no hidden characters in the middle. (E.g. some will have the option to “show invisibles” or something).
1099  Alternate cryptocurrencies / Altcoin Discussion / Re: "BITCOIN CASH IS BITCOIN NOW." on: November 12, 2017, 05:22:38 PM
OP please put this in the news section next time.
And link the source!
You could have at least mentioned that this is a article from coindesk!

Please DON'T put it in the main bitcoin news section since it is about an alt-coin and doesn't belong there.

If you love centralized control by miners under the thumb of a authoritarian regime, go for bitcoin cash.
1100  Bitcoin / Bitcoin Technical Support / Re: password correct, but not working on: November 11, 2017, 03:53:15 PM
Suddenly, I cannot unlock my Bitcoin Core encrypted wallet. I was sending and receiving transactions only a few days ago. I am certain that I am using the correct password because I had backups of the password, and it is correct. My bitcoin remain in the wallet, but I cannot move them. I moved the wallet.dat file to another computer, but I get the same error on using the password. Is it possible that the recent upgrade to v0.15.0.1 affected the password?

What if you restore a backup that was made prior to the issue?  Does it behave the same way?
