Re: [ANN][Airdrop][$LOK] Loki - Private Transactions & Comms
I heard lots of good things about this project but it looks like there is no ICO and only private sale for rich investors, this sucks for normal people like us...
Hello Dirk! Sorry to hear you could not participate. The upcoming airdrop is for our community!
There are currently three ways to obtain Loki currently:
1) Mining when Mainnet launches later this month
2) Participate in the upcoming Airdrop
3) Solve the Twitter puzzle
Is there a date for the start of the airdrop yet?
Watch out for the Airdrop!
How many coins does each person get from it?

SWAP REMINDER
The last day for the 1:1 swap ratio for HTML:HTML5 is February 12, 2018. This is true regardless of where or how the HTML5 coins are held. As everyone, including Yobit users, have had ample time to swap their coins, there will not be any exceptions to the swap ratio timeframes.

What have you done with the unswapped coins? Have you burned them?
Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
all I see right now
is a 6-months long cup and handle formation
How about double top with the lower second peak?is a 6-months long cup and handle formation
Is this a sole "contrarian view", or are there more who expect a proper correction right now?
I think the price doubled because of the halving, and it's not going back down because the miners don't have as many coins to dump. There have been double tops without corrections, and cups without handles. Chart formations don't always work, unless somebody has coins to dump the price isn't going back down.
Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
No targets. I'm just showing that lots of traders are going to playing a support roughly in the vicinity of 650 and you might want to watch out if that fails.
It's frozen at 700 for now. The walls look evenly balanced on stamp, but on finex there is a wall at 720 that looks ripe for being demolished. The impression I get is that it's going up so it might be going down because I usually get it wrong. I'm hodling for now because I normally lose on short term trades. Whatever it does in the next few weeks I think in the long term it's going up.
Re: Consifering US dollar is very strong recently, breaking 700 means a lot
The Swiss national train service making Bitcoin purchases available through all its ticket machines means a lot. Breaking 7000 isn't inconceivable next year with mainstream companies like that taking Bitcoin seriously. Bitcoin's all over the news again, and for the right reasons. The news of the Bitfinex hack held the price down, but once good news started again the price started breaking upwards.
PS
The OP ihas a typo in it, "Consifering" should be spelt considering.

Re: Netflix Executive Wants Bitcoin as Global Currency, Considers It Cost-Effective
Isn't this old news? and netflix haven't started accepting bitcoin yet. 
That's what I thought too. I seem to remember this being mentioned a relatively long time ago.
Netflix "opened the possibility of accepting Bitcoin payments" on January 6th, but I couldn't find an option to pay with them on the Netflix website yet.

On January 6th, during the Citi 2016 Internet, Media & Telecommunications Conference, Netflix CFO David Wells opened the possibility for Netflix to accept Bitcoin payments.
Like so many other businesses, Netflix relies on people not being bothered enough to cancel their subscription. If I had to manually do it every month I'd certainly think twice. I wonder how they plan to get around that little bit of psychology.
Netflix would probably use the same prepay system for Bitcoin that it has for gift cards. It deducts the monthly charge from a gift card balance each month, and I assume stops providing films to anyone with an empty balance. For Bitcoin it could ask for payment once a month, then stop providing films to anyone who doesn't pay.
Although Netflix relies on people not being bothered enough to cancel their debit card subscription it seems to terminate gift card subscriptions when a gift card stops paying.

Netflix Gift Cards in Asia-Pacific
You can use Netflix Gift Cards to prepay for a Netflix subscription or to give as a gift to friends, family, teachers, and more. These gift cards are available at most major retailers in the following Asia-Pacific countries:
Australia and Japan.
You can purchase a Netflix Gift Card at many retail locations, and apply the gift card to your new or existing Netflix account. We will deduct the appropriate amount from your gift card balance based on the plan you've chosen. If you're new to Netflix and haven't had an account before, you will receive a free month of service, in addition to the amount of the gift card. After the free month, we will start to deduct the monthly charge for your plan from your gift card balance.

Re: Winklevoss bitcoin etf coming soon...maybe by oct 12
Current situation seems awfully similar to hype before previous project of Winklevoss - Gemini was announced.
People were saying back then - after Geminin will go live it will dominate market and price of BTC will skyrocket for sure.
And we all know what happened. Gemini is online and I personally don't know anyone who used it. Also it had zero impact on bitcoin price.

Gemini's volume was pathetic to begin with, but it's now at 6th place, above bitstamp and bitfinex. I had written it off as a failure, but it's taking off now. I had also written the ETF off as a failure, but might be wrong about that too. It could take a long time, but turn out to be successful.
Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
That is one big f'g tree, but getting back to topic - usd collapses, USA falls as a power, etc etc etc... not gonna happen in our lifetimes you nutballs, but it will happen eventually I would think.
Here's another one that's so big you can drive a car through, but cutting the hole didn't kill it so it doesn't have any trophy kill pictures.
As for a USA and dollar collapse, I don't think it will happen this century, if ever. Bitcoin will get new all time highs, but not because of a total USA/dollar collapse.
Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
Margin Trading has been active for the last 6 days. All the API keys were all revoked after the hack, so anyone using a bot has to get new ones to start trading again.
After 6 days most bot traders who intend to start using Bitfinex again will have sought new keys, but a few stragglers might rejoin over the coming week and increase the volume a little more.

At this point, we cannot completely attribute the cause of the loss of volume - yet a fair inference does come from loss of confidence. On the other hand, before the "hack", quite a bit of Bitfinex's volume seemed to have come from margin trading, which appears to have not been re-enabled, yet.

Is Electrum still safe to use?
It's help window says it connects to a single server to get your transaction history, and I assume that server is backed by a single Bitcoin core node.
In addition, its help says it connects to several nodes to get the headers and uses them to verify the transaction history sent from the single server.
Even if the server and all nodes a wallet uses were compromised I can't think of a way your Bitcoins could be at risk of theft if you sign Electrum transactions offline, and only transmit them through a watching only wallet connected to the internet.

A decentralized exchange is a good idea. The methods we currently have implemented are not. There have to be ways to independently verify the occurrence of an exchange, similar to how miners verify transactions through mining. If we can get something like that working (but it moves quite quickly), then we might see something of value come out of this idea, but there are still some things that have to be worked out. Not all of it is good enough yet for it to be implemented.
The concept of a decentralized exchange is good, but the first one to get high volume will become the target of the same hackers that go after centralized exchanges. Any bugs in the code will be exploited, and there will probably be bugs at first. I suspect the first decentralized exchange to get high volume will get hacked, just like the decentralized exchanges do. Making it decentralized doesn't make it invulnerable to hacks.
I cant be hacked, the money is stored on your PC, and the hacker to go after 1 person is stupid. The risk is distributed, there is no central wallet to steal from.
That is the point, the bugs will only do minor damage in my opinion, and can be quickly corrected.
The money is stored on your PC when you aren't trading, but after you start trading it would be under the control of whatever code the decentralized exchange runs on. A hacker who found a bug in that code could make a bot to exploit it through thousands of different trades simultaneously. Anyone trading at that time could have their Bitcoins stolen.
I think you could use the wallet on two separate devices simultaneously. If you tried to spend from both separate devices simultaneously both transactions would be broadcast, and the network would accept one which would invalidate the other.

I doubt accepting unconfirmed Bitcoin transactions as payment would cost a machine operator much in double spends. It's too much work to attempt a double spend for a bar of chocolate.
double spends are actually easier then you think.
small items are treated as dust. so send a payment with zero fee to the vending machine. and also on a phone send the same inputs to yourself with a fee.. 98% of the time the tx with fee going back to you gets accepted. and the zero fee drops off the mempool unconfirmed.
all it takes is 2 transactions.
to make it easier. if you know the PUSHTX addresses of pools, to API call your tx (with fee to yourself) to the pool direct, and know the ip addresses of the vending machines block explorer to send the zero fee tx. you can time it right to send the zero fee tx to the vending machine. and get ur food and send the other tx (to yourself) to the mining pool to get the better chance of both "businesses"/nodes not seeing the other tx first
it doesnt require any expensive equipment. just good timing
I think that what he's trying to say is that no-one will be bothered to. But in actuality, you could even make a script for double-spending.
That's what I was thinking, but after reading franky1's comment I'm not so sure.
Is there a simple way to minimize the risk of double spends through a machine? Would requiring a minimum fee, or getting the machine to API call any tx to all possible pools direct work?
How does Bitpay manage to accept zero tx payments? Couldn't a machine copy Bitpay's methods?
Bitcoin vending machine owners have less chance of losing money through Bitcoin than if they had a cash vending machine.
People are constantly inventing new ways to trick vending machines by putting fake coins into them. Sometimes vending machines have registered low value foreign coins as high value coins of a different currency. There have even been some machines that accepted washers as real coins.

There was a way to trick some machines by using a 10 baht coin (worth only 0.25) as a 2 euro coin.

A slug is a counterfeit coin that is used to make illegal purchases from a coin-operated device, such as a vending machine...
By resembling various features of a genuine coin, including the weight, size, and shape, a slug is designed to trick the machine into accepting it like a real coin.
Though slug usage is a violation of the law, prosecution for slug usage is rare due to the low value of the theft and the difficulty in identifying the offender.

The 2 euro coin is similar in size to the 10 baht coin (worth only 0.25). Some vending machines used to accept this coin as 2 euro. They have since been upgraded and will not accept it anymore.

6.14 blocks per hour, hashrate rising slightly ... so much BS FUD and failed doomer-mongering around the halving, what's the next propaganda meme they'll try bashing bitcoin with? ... every cheap shot and underhand trick they try only makes bitcoin more resilient , diminishing returns, soon it will be cheaper to just buy bitcoin and get on board, just like mining at some point it is more profitable to be an honest miner.

The big dump near halving time could have been due to a manipulator trying underhand tricks to suppress the price because he shorted the halving. If it was he failed, it floated back to near where he dumped within a few hours.
Re: Wall Observer BTC/USD - Bitcoin price movement tracking & discussion
wooooo please tell me again how great brexit is for bitcoin.
Although I don't believe politics like BREXIT will be left unmanaged by the Elite, let's see something here that most people overlook: Assume you are british.
What's best for your networth? Local fiat (GBPs) or BTCs?
The pound's going to take more of a beating, and any Brits who are aware of Bitcoin will start thinking about buying some. If they do well out of it they will tell their friends who aren't aware of Bitcoin. Also if the euro starts taking a beating the same could happen all over Europe. That demand could push Bitcoin over $1000 before the Autumn even without the approaching halving.
Re: PayPal Stops Operating in Turkey, Online Payment Sector Turns to Bitcoin
Wishful thinking. 2.7 million is still somewhere around nothing in a country of that size even if some growth is encouraging. If the Turkish government shut them down then the Turkish government is gonna provide a local alternative.
China has alipay which is its largest third-party online payment solution. Similarly Turkey might invent its own alternative to paypal. However, if that alternative integrates Bitcoin into its system it could be bullish.
