1  Bitcoin / Bitcoin Discussion / Bitrefill has received more than 1[btc] in payments through Lightning Network on: May 23, 2018, 04:26:23 AM
Bitrefill is a service which you can use to top up your phone, pay the bills, and a lot more... using bitcoin and it has been accepting payments through Lightning Network. the testing started before Dec 2017 and they have been accepting payments through LN ever since Mar 15 [1]. now they have set a new record: 1BTC received through Lightning Network as payments.

more than 2000 nodes are already running on Lightning Network.

Katy Perry talking with Warren Buffett about cryptocurrencies.
Warren is sad because Berkshire Hathaway is tanking hard and Katy is thinking "this dude doesn't understand bitcoin at all".



after a heated debate Warren whispered in Katy's ear that he is a bitcoin whale.



later on Katy decided to go back, this time with Crypto Claws™

3  Bitcoin / Electrum / Version 2.9.4 on: January 23, 2018, 05:02:04 AM
11 days ago there was a release on Electrum's github repository [1] tagged with version 2.9.4 (the latest 2.9.x version was 2.9.3) and based on the 2.9.x branch it seems to have backported the JSON-RPC vulnerability fix [2]. there are no binaries for it though [3].

so i was wondering if "as the last resort" if someone could not install version 3.0.5+ on windows, is 2.9.4 a viable option?

4  Bitcoin / Bitcoin Discussion / 2018 bitcoin milestones: 2.2 MB block and 81 LN nodes 171 channels on: January 21, 2018, 05:14:23 AM
Block #505253 is the biggest block mined yet on bitcoin with 2217.342 kB in size.

i find it very interesting that the number of transactions in the biggest blocks ever are extremely low compared to the usual number of transactions per block!

then i look at this chart and things become even more interesting. seems like somebody has been very busy in the past 30 and the past 3 days Wink




and of course the size matches perfectly:


5  Bitcoin / Bitcoin Discussion / Buying coffee with bitcoin... on: January 01, 2018, 04:32:22 PM
Enjoy...

In this video Laolu (co-founder of Lightning Labs) demonstrates a multi-hop payment on Bitcoin's mainnet which travels across the 3 major Lightning implementations. In the demo Laolu (a.k.a roasbeef) sends a payment from our Lightning desktop app (https://github.com/lightninglabs/lightning-app) to Starblocks, a coffee payment demo. This payment marks the first multi-hop, cross-implementation payment on Bitcoin's mainnet. All transaction performed in the video were performed completely off-chain, instantly, and with virtually zero fees. Lightning allows instant, low-fee payments on Bitcoin, enabling the system to scale further for the next wave of adoption. Additionally, Lightning unlocks a new class of use cases for Bitcoin enabled by the ability to instantly send low-fee payments on the system.

6  Economy / Speculation / Bitcoin setting records, $19.8k and half a million blocks milestone on: December 19, 2017, 04:33:46 AM
these past days we have had a new ATH $19,892 for price on Coinbase which is a phenomenal record in history of bitcoin.

but that is not the only one. in case you missed it, recently block #500,000 [1] was mined. that is half a million blocks mined. and with Genesis block [2] on 2009-01-03 that is nearly 9 years of bitcoin being around and still going strong despite all the naysayers and doomsday machines repeating obituaries for bitcoin all this time.

congratulations to all of us pioneers. the early adopters who are starting at the ground floor.

7  Economy / Scam Accusations / [Bittrex] account downgraded, 1 month no answer from support, funds blocked on: November 15, 2017, 05:34:21 AM
as i said before in their announcement topic [1] i have a very old account with https://bittrex.com
bittrex had an account type called "Legacy" which meant you didn't have to verify your account (give any kind of information/documentation) to be able to trade or withdraw large amounts. my limit was 2000BTC daily which was reduced (site-wide for this type of account) down to 1337BTC when price went up a lot this year.

about a month ago, with no warnings or anything they downgraded my account to "Basic" and now they are asking (forcing) for my personal information which i am not willing to give them.
and now my money is blocked in their website and i am unable to do anything about it.

1 month ago i created a ticket with their support team (303970) but to this  date i have not received any answer apart from the automated ones telling me to wait and not make duplicates.

this is unacceptable and clear example of robbery.

8  Bitcoin / Bitcoin Discussion / There has been 667 forks from bitcoin (altcoins), 3 this month on: October 20, 2017, 04:56:06 AM
i just found a very interesting website (http://mapofcoins.com/) which has interesting information about forks from different cryptocurrencies.
the bitcoin fork map (http://mapofcoins.com/bitcoin) specially took my attention.

according to this site there has been 667 forks in total, 3 of which belong to this month alone.

you can click on the names of these coins and see the code and their website. a lot of them didn't even bother making more than 20 commits in years! or even change anything meaningful when they fork!
9  Bitcoin / Bitcoin Technical Support / (0 fee transactions) does amount matter when nodes reject tx?! on: October 10, 2017, 05:23:36 AM
for the past 10 days i have been trying to broadcast a tx with 0 fees and it is being rejected.
i can't share it for privacy reasons but it is a normal transaction has 1 input and 1 output.
the coin age is ~1000 blocks
amount is >0.01 & <0.1BTC
fee 0
* this is being rejected by all nodes that i have tried. at first i thought it is the new change in Core v 0.15.0.1 regarding minrelaytxfee and removing priority,... but even core v 0.14 rejected me
also tried blockchain.info and other explorer's push option and didn't work (all rejected me).
hence the question: does amount matter?


p.s.
https://blockchain.info/tx/8f85f5b941d02c0c249dd6445f73557d4c1838c16b9f9220d63ec84af983ce90
went through like a charm! amount is 0.157BTC pushed using https://blockchain.info/pushtx but pushing the above tx gives me the following error:
Code:
Validation Error: Insufficient fee. Minimum fee is 1 sat/B.

no node rejected it either!
10  Bitcoin / Bitcoin Discussion / US to remove taxes on bitcoin! more bitcoin=currency stuff on: September 17, 2017, 01:06:26 PM
the news is 10 days old but i have not seen it here so far, so here is goes:

finally US is catching up to the world!
in Tax Fairness Act of 2017 it proposes that customers do not need to report transactions less than $600 worth. this is great but it is while Japan and Australia have completely removed taxes from any bitcoin transaction no matter the size.

#baby_steps

Cryptocurrencies can be used for anything from buying a cup of coffee to paying for a car, to crowdfunding a new startup and more and more consumers are choosing to use this type of payment.  To keep up with modern technology, we need to remove outdated restrictions on cryptocurrencies, like Bitcoin, and other methods of digital payment,” said Polis.  “By cutting red tape and eliminating onerous reporting requirements, it will allow cryptocurrencies to further benefit consumers and help create good jobs.”

“Individuals all over the world are starting to use cryptocurrencies for small every day transactions, yet here in the States we have fallen behind and make cryptocurrency use more of a challenge than it needs to be,” said Schweikert.  “With this simple legislative change, anyone can make digital payments to buy a newspaper or a bike without worrying about tax code challenges.”

“While Bitcoin and other cryptocurrencies are technologically innovative payment methods, today you have to keep track of and report every transaction you make using them, whether it’s a $10,000 investment trade or whether you’re buying a 99¢ song online or a latte at a café. This obviously creates friction and puts cryptocurrencies at a disadvantage relative to other digital payment methods,” said Jerry Brito, Executive Director of cryptocurrency think tank Coin Center. “We applaud Representatives Polis and Schweikert for their leadership in introducing the Cryptocurrency Tax Fairness Act, which would treat cryptocurrencies similarly to how foreign currency is now treated and relieve users from having to keep track of small personal transactions. Not only will this create a level playing field for digital currencies, it will also help unleash innovation on applications like micropayments, which can consist of dozens of transactions per minute and thus are difficult to square with the current law.”
11  Economy / Speculation / China banned bitcoin: 2013 VS 2017. market maturity? on: September 11, 2017, 04:31:48 AM
this is not the first time that the news, um i mean the lie about China banning bitcoin comes out. because in fact China has never banned bitcoin!

on 5 December 2013 China prohibited their banks from investing in bitcoin, the FUD said China banned bitcoin and all the things you are seeing today.

the price took a dive about 33% in the first hour and in about 4 days bitcoin lost half its value (-50% drop) before it started recovering as the FUD cleared up.



in case above pic didn't show up: https://bitcoincharts.com/charts/bitstampUSD#rg60zig2-hourzczsg2013-12-04zeg2013-12-09ztgSzm1g10zm2g25zp

now in 2017 we have had the same thing. first the ICO thing which didn't even have anything to do with bitcoin, and then this new FUD about China banning bitcoin again!

this time however, bitcoin barely dropped 5% in the initial hours and the total drop was about 10%



in case above pic didn't show up: https://bitcoincharts.com/charts/bitstampUSD#rg5zig2-hourzczsg2017-09-07zeg2017-09-11ztgSzm1g10zm2g25zp

is the market getting more mature that the FUD is less effective now?

13  Bitcoin / Bitcoin Discussion / did the BCC fork already happen or what, i'm confused! on: August 01, 2017, 03:14:43 AM
according to the specs the bitcoin cash hard fork should happen on epoch 1501590000 which is equal to Tue 1 Aug 2017 12:20:00 UTC.
according to https://time.is/UTC it is 3:12!

here is the confusion. Yobit credited my account with the same BTC amount i own in their new BCC market!!! (i had 10,000 satoshi by the way Tongue)
i am guessing it is their shitty service that doesn't even know what is happening. but thought i ask here in case i am missing something.
14  Bitcoin / Electrum / [WARNING] be careful about Electron Cash or the fork of Electrum for BCC on: July 31, 2017, 04:36:38 PM
the http://www.electroncash.org/ website which is being blocked now by my Antivirus as a malicious site (Eset Smart Security 10.1) so i can not and will not check and see if the GitHub repository that people advertise is also listed there or not (don't have a sandbox to check).

but i see people advertise this as their repository: https://github.com/fyookball/electrum
this is the same person: https://bitcointalk.org/index.php?action=profile;u=261027

and there is a Warning issued by ThomasV (the creator and maintainer of the original Electrum repository) which i will share here:

WARNING: "Electron Cash" will copy all your Electrum wallets to its own directory, and their binaries are anonymous:

this is the linked commit: https://github.com/fyookball/electrum/commit/0fc02cceee9d3465849dcecb2c1126de7cf65550

Note: the BCC version was renamed to "Electron cash" instead of "Electrum cash". and it is just a rename. so don't be confused.


Plain English aka Newbie friendly
do two things:
1. if you wanted to use Electron Cash, download and compile from source code NOT the binaries.
2. follow https://electrum.org/bcc2.txt you can use a live linux for your "another machine"
15  Alternate cryptocurrencies / Altcoin Discussion / [GUIDE] How to claim Bitcoin Cash on: July 30, 2017, 04:00:53 AM
Make sure to see this topic by theymos also: https://bitcointalk.org/index.php?topic=2059111.0

Note: I do not condone this behavior but it is happening and many consider it as "free money" or "airdrop" so i've made this to help prevent loss and possibly help those who want to sell as fast as possible to get the best price as it goes down.

On August 1st, a small group of people are planning to implement a non-compatible upgrade to the network, raising the blocksize limit to 8MB and removing SegWit. As this upgrade does not have a wide backing of the network, this "hard fork" would split the Bitcoin network in two. After this split whatever amount you have in bitcoin you will have the same amount in their chain known as Bitcoin Cash (BCC for short).
These are the ways you can claim it and be the safest possible:

According to this [1] and [2] BCC has a two way replay protection. This means if implemented correctly and honored by miners any transactions made in BCC chain should be invalid on bitcoin chain and vice versa. This makes things a lot easier.

Ways to claim your BCC:

Method 1, using an exchange before August 1:
Risky, for the Lazy, Easy
Some exchanges have promised to credit their users their BCC tokens in case the split on August first happened. this means if you have any balance in your account there you will automatically receive the same amount in BCC.
Risks:
1. Your account can get hacked, the exchange may get hacked, the exchange can run away.
2. You don't control the private keys so you are trusting the third party to do it for you. and they may mess up and lose the tokens.
3. It may take a while before they credit your BCC tokens, or add a market for you to be able to sell them, or let you withdraw them to sell elsewhere and every second counts in case you want to act fast to get the highest price.

Benefits:
1. It is easy and suitable for the lazy.
2. If the exchange has the market already or adds it fast on August 1, you can be the fastest to sell without missing a second. So you will get the best price before it crashes.

Important
Read the risks and understand them before you decide on doing this.
your time is running out, some exchanges will close their deposits on 31st. Make sure it is not yet closed, you don't want your coins in limbo!


Method 2, using a BCC client After August 1:
Harder, Safer
This method requires you to do everything, this means separating your coins yourself and then spending them. It is not hard, but it takes some time to do it. You also are taking the risk of using a new untested code given to you by people we don't know and have no track record to check.

Risks:
The BCC clients are new and unknown, and we do not know who is releasing them (do not confuse the similar names such as "electrum-cash" with the original client "electrum" they are different[3]). They are rushed and nearly untested. They may have bugs or worse. Extra care should be taken (explained in summary below)
The replay protection may not work (Don't think this is true, just a cautious assumption IMO) (explained in summary below).

Benefits:
You control everything!

How To:
Summary: My approach is to separate the coins first and then spend them, this way you don't have to worry about replay protection or the wallets you download (because it is a new wallet created by a small group of people we don't know or trust and it is rushed and untested).
This is all After August 1 and the split.

1. First split your coins by spending them on bitcoin's network. Simply get a new key and send all your funds to it with the wallet client that you already have and is running on the main network.
Extremely Important
If you are using a deterministic wallet (ex electrum with seed) you must create a new wallet with new seed not just a new address from the same seed. (edit: Read about Electrum WARNING)

2. Download a BCC client to import your old keys (which are now empty of bitcoin but still have BCC) and use them as you wish.
I am aware of 2 clients (download at your own risk):
- Bitcoin ABC: You can download it from "releases", compile the repo or download binaries from their website.
This is a full node.
Link: https://github.com/Bitcoin-ABC/bitcoin-abc
- Electrum Cash (This is a changed/edited version of Electrum by other people than Electrum team [3])
This is a light wallet (SPV)
Link: http://www.electrumcash.org/

Important
It is best if you do all this offline and on a separate computer and preferably on a live linux with no persistence and no access to any of your hard disks.
Suggestion: Ubuntu[4], Tails[5]
- Burn them on a DVD or make a Live USB [6][7]
- Disconnect internet (if you do it, you need to make a raw unsigned transaction online and transfer it to offline system to sign)
- Boot up into that Linux
- install BCC client and import your private keys (or seed if it is electrum-cash)
- spend.

If you found any mistakes or lack of explanation help me fix them.

18  Economy / Speculation / My bitcoin speculation for August... Only rise is possible... on: July 12, 2017, 04:28:33 AM
we all know that this dip is because of the fear of August 1st and the possibility of a chain split because of the deadline that BIP148 has set.
while many believe that BIP148 is going to fail, i say although it will fail but it is not a failure. the best result of it was the SegWit2x which currently has 91% of the miners support. whereas BIP141 (SegWit) has 46% support.

now the speculation. Grin

i say we are going to have SegWit activated on August 1st by SegWit2x (which needs only 80% support and now has 91% support) and that will lead to a big price recovery and another bull run.
we saw the same thing about activation of SegWit on litecoin. they delayed the activation as much as possible, also caused a big dip after LTC's big rise and then it was activated with nearly 100% support and price jumped another time.

this following chart is happening all over again. this is the same fear. the fear of a hard fork and a split. the difference is that the picture below was because of BU split and now it is the SegWit split. and both of them are because of drama and had a very small chance of coming to reality.



i will expect $3000 be broken if things go as planned. buy the dips then

but it will probably only last about 4-5 months until the second deadline which will be 6 months after activation of SegWit (in 2018). and we may see another one of these.

now by that time either SegWit has lived up to the promise (and it is good enough time to see) and they give up on the 2MB hard fork or we will see the drama all over again over hard forking to a 2 MB base block size.
19  Bitcoin / Bitcoin Discussion / removal of taxes on bitcoin and recognition as currency is booming in the world on: July 02, 2017, 04:02:59 AM
Japan exempts bitcoin from Consumption Tax

The exemption from Japan’s 8% indirect tax regime recognizes bitcoin as a private currency used for the exchange of goods or services, and that the currencies hold no intrinsic value. The measure has come into force from 1 July 2017.

Traders of bitcoin will though remain liable to tax on their gains – capital gains tax or corporate income tax.

Australian's New Budget Includes a Bitcoin Tax Cut

Australia has officially confirmed it will treat Bitcoin “just like money” from this year and it will no longer be subject to double taxation.

20  Alternate cryptocurrencies / Altcoin Discussion / a friendly warning about "advertisers" on: June 13, 2017, 08:00:35 AM
... mostly towards newcomers

i see an increased activity in people advertising altcoins as good investments which are going to be such and such in the future and do wonderful things! specially in the main board. and it is only going to increase as the bubble of said altcoin grows bigger.

just remember to think before investing in any of them, don't fall for the emotional hype.

also a good idea to educate yourself. start by reading this: http://www.investopedia.com/terms/b/bubble.asp
