81  Bitcoin / Bitcoin Discussion / Re: Bitcoin as payment system on: December 04, 2017, 11:13:49 AM
We all know that Bitcoin is one of the best ways to invest your money. However, we know that Satoshi wanted to change money as we know it rather than new investment model.

I think these are two sides of the same coin. Remember Satoshi's message from the genesis block -- a reminder of the bank bailouts and the threat they are to the integrity of money. Sound money is both an investment and a medium of exchange.

How do you think, will we be using bitcoin as payment system? Or it will stay as it is and this bubble blow up one day?

There will always be demand for robust, censorship-resistant, permanently stored public payments and data. For transferring lower value, I think that the Lightning Network (payment channels) will serve our needs well. Even if it turns out to be a hub-and-spoke model, it'll still be trustless. Since confirmations aren't required for LN transactions, fees will be much lower. Satoshi had payment channels in the original software, and now that we have addressed transaction malleability, we can start using them.

HODL bitcoin? why and why not?

It's easy to think you can beat the market, but timing and correctly trading price corrections is easier said than done. Often times, you'll just be selling the consolidation before new highs. The same goes for crashes: many people sell when it's most painful, right near the bottom. It's important to resist the urge to sell during these "capitulations." Because there's a good chance you'll lose coins in the process.

Long term, it's becoming clear that Bitcoin is here to stay. It's becoming economically relevant. Seeing the 2013 and 2017 cycles play out have me convinced that we won't see prices below $5,000 or possibly even $7,500 again. We're getting to the point where most of the world is getting priced out of owning a single Bitcoin!

Which are some new cryptocurrencies in the market which seems promising and can compete with bitcoin in near future?

I'm not sure that anything is competing with Bitcoin. The best developers in the space are working on it, its network size is unmatched (this can't be measured by transaction activity due to hodlers), and it has a big first mover advantage.

As such, the most promising cryptocurrencies are not directly competing with Bitcoin, but rather explore different use cases altogether. The main areas I'm focusing on are anonymity/privacy coins and decentralized exchange (DEX) coins.

For privacy coins, I like Monero, Zcash, Verge, Zcoin.... but more than anything, I am looking forward to MimbleWimble, which will apparently be launched as its own blockchain next year. For DEX coins, I'm interested in Blocknet, Komodo and Bridgecoin.
84  Bitcoin / Development & Technical Discussion / Re: Linking fees to fiat? on: December 04, 2017, 10:18:20 AM
Quote
The only thing we can do is to spread the word. Every time there is a temporary surge in transaction fees there are dozens of threads on this forum and plenty of people complaining in chat rooms. That's a good opportunity to educate people how it all works.

This seems like a good starting point and we can go from there. A more fast approach will be to contact the different wallet developers and ask them to make the move. Set the recommended fee to '0.05 Cents' per transaction. I know this will only increase the on chain transactions but Eventually the memory pool will clear out and a new standard will be set. Same can be done for priority transactions and set the 'fastest fee' to 0.50 cents. Don't know how many developers will be willing to do this.

It makes no sense to associate fees with fiat value. There's no decentralized way to link fees to fiat; it would require centralized coordination every step of the way. Bitcoin is meant to function via incentives through its native currency. Fiat should be irrelevant.

Fees are denominated in BTC, and Bitcoin's deflationary supply means that transaction fees will rise (as denominated in BTC) over time to replace the block subsidy. I'm actually annoyed that Blockchain.info shows $ value by default rather than BTC value. If you expect the price of BTC to rise, then you better get used to the cost of fees rising too. Block space is a valuable and scarce resource, so it's priced accordingly.
85  Economy / Web Wallets / Re: Fee too low on: December 04, 2017, 05:32:01 AM
Transaction is still pending! It's been nearly a month, I received a generic email response from support. Does anybody have any other ideas?

Odd, I figured that Blockchain.info would make the inputs spendable again by now. Three weeks? Their wallet is even worse than I thought.

The easiest thing to do is export the private key(s) or wallet seed and import them into another wallet like Coinomi or Ledger Wallet. You can then spend them again with a higher fee. If it's an HD wallet (created in the last ~2 years), you can go to Settings \ Security \ Wallet Recovery Phrase to get your BIP39 seed, which you can import into another wallet.

Otherwise, you can go to Settings \ Addresses \ Imported Bitcoin addresses. On the right hand side, there is a drop-down menu that will allow you to copy the private key for the address(es) in question. This should be in WIF format by default, which you can import into Electrum, Coinomi, or many other wallets.
86  Bitcoin / Development & Technical Discussion / Re: brain wallets - good or bad on: December 03, 2017, 08:28:01 PM
brain wallet is the most secure of all only if u don loose your mind

I can understand why beginners think this is true, because they only think of Bitcoin wallet hacks as "computer intrusions." The problem is that your mind is not capable of being truly random when you are generating the brain wallet.

Brain wallets usually end up being very low entropy because of the way the human mind works. In turn, you are always at a much higher risk of a dictionary attack or similar kind of brute forcing to decrypt your private key.

Also a few large databases of passwords have been leaked meaning so it is quite easy to hash all these passwords and then see if their corresponding address exists as an active address on the blockchain – if so you have the private key and therefore access to the funds.

That's interesting. It never occurred to me that the massive bitcointalk leaks, for instance, might be valuable as brain wallet decrypters. I wonder how many people generate a brain wallet based on compromised passwords/passphrases, only to have them immediately wiped when they fund them.....
87  Economy / Exchanges / Re: Australia exchange on: December 02, 2017, 11:56:26 PM
Have to say the exchange in Aus sucks..

That's right, so it is important for me to get another way to join in the cryptocurrency exchange.

I'm not sure about exchanges based in Australia -- Coinjar is the only one I've heard of and I don't know anything about it. But I have an Aussie friend and he does all his Bitcoin trading on Bitstamp. He wires AUD to Bitstamp and they convert it to USD to trade. They're one of the most reputable exchanges on the market, so if it comes down to them and BTCMarkets, I'm choosing Bitstamp every time.

For whatever reason, Aussies aren't allowed to trade on GDAX, which is probably the safest place on the market to dump USD while waiting out price corrections in BTCUSD. However, Aussies can buy on Coinbase. They cannot sell nor can they use the exchange interface (GDAX).

I've heard that some Aussie traders buy BTC on Coinbase, sell it on Coinjar and wire AUD back to their bank account.
88  Economy / Invites & Accounts / Re: need a Enhanced Verified Bittrex Account on: December 02, 2017, 11:48:22 AM

guys i have second thought.the issues is when i bought an account from someone and start depositing and trading. person whom sold me this account can contact bittrex with phone and take back his account, right?

im willing to go first and remove the authenticator if needed
authenticator is not the problem. the person can personally contact bittrex (via phone or physical) and tell them someone hacked my account and email.
and prove them she/he is the real person with identity document. then get back the account.
I don't know maybe i'm wrong. there is a lot of topic in this section that people selling verified paypal account!

Yes, it would be trivially easy for someone with enhanced verification to take their account back. The case would probably take weeks to process, but the account would be frozen in the meantime. They could claim their account and email were hacked, provide ID and recent proof of address that match the account, and their IP log will appear like the original account holder. It would probably be an open/shut case.

Also, most people willing to sell a verified Paypal account are probably selling hacked accounts. I assume the same applies here. If it were me, I'd be worried that the buyer would transfer darknet market coins or otherwise illicit/blacklisted coins into the account, or otherwise get me potentially involved with shady stuff.

I understand why there's a market for this, but I would be too paranoid to be either buyer or seller in this situation.
89  Economy / Service Discussion / Re: What's the current state of new Bittrex accounts? on: December 02, 2017, 10:59:18 AM
Why is verification a problem for you?

Would you rather to have millions of scammers hiding behind crypto and scamming people only to anonymously sell their coins on unverified exchanges?

If you re not a scammer, you ve got nothing to hide.

WTF can they do with my Name and my ID number?

It's more than that. For US users: Name, address, birth date, last four digits of Social Security number, scan of ID and selfies. It's not all the information required to steal your identity, but it's most of it. In particular, I am very uncomfortable giving out the last 4 of my SSN. The first 5 digits of someone's SSN can be predicted using other personal information (like state of birth). As such, giving out the last 4 of your SSN is dangerously close to giving out the entire number. And once your SSN is stolen, game over. You'll never get a new one.

Fraud and ID theft are rampant, and these exchanges are targets for hacking. They're not banks, either. They're shitcoin exchanges. Do you really trust them with your data? And who is this Jumio company that Bittrex contracts with to do enhanced verification? Why should I trust them?
90  Economy / Exchanges / Re: Top exchanges on: December 01, 2017, 08:10:28 PM
Just starting out...what are the best, safe exchanges to buy/sell bitcoin, ethereum if you’re in the US. What about trading for alt coin?

Keep in mind that no exchange is "safe" for holding cryptocurrency. Even reputable exchanges get hacked. That said, the safest exchanges for US residents are Coinbase/GDAX and Gemini. Bitflyer has also just launched in the US; they are the biggest Japanese exchange and appear to be obtaining licenses in every US state they operate in.

Altcoin exchanges are risky. Poloniex and Bittrex are the biggest exchanges, but they are now notorious for support backlogs, account/withdrawal disabling, etc. Binance and HitBTC seem to be the most popular alternatives for now, but you should be aware that as users flood these platforms, performance tends to significantly degrade.
91  Economy / Speculation / Re: Nasdaq Plans to Launch Bitcoin Futures in First Half 2018 on: November 30, 2017, 10:30:46 PM
I can't help but think the institutions are concocting a scheme to destroy bitcoin using these cash settleled futures markets somehow..

I'm very suspicious..

How is it that we can't get an etf no matter how hard we try but hey, they can just pop up futures markets like no big deal..

It's definitely clear from the CME and Nasdaq getting involved that Bitcoin is going mainstream from an investment perspective. That's definitely a positive development, but I'm concerned about the impact that regulated futures markets will have on spot BTC prices. As I understand it, these markets will be run during standard market hours (Monday-Friday) with circuit breakers and other volatility-reduction mechanisms. And I think we all recognize the amount of capital that Wall Street can introduce to the market -- that goes for both the long and short side.

Are there any ongoing discussions/threads about the impact that these new markets will have? The spot market used to follow China. Now it seems to follow Bitfinex/Bitflyer. I wonder if it will follow CME/Nasdaq in the future.
92  Bitcoin / Development & Technical Discussion / Re: Question on RBF on: November 30, 2017, 10:20:33 PM
I have a question, say I broadcast a transaction with an RBF flag, and then try to replace it with a new version at a higher fee.
Is there not a case in which some nodes that don't support RBF reject it as they see it as double spent.

I think this is the case, but you never know until a service (node operator) tells you so. During one of the recent spam attacks (when high priority fees were reaching 1000 satoshis/byte), I submitted a stuck transaction to an acceleration service on the forum. It was an RBF transaction that had already been submitted with a higher fee, since the network fee rate kept increasing.

I was told that the transaction was a double spend, so it couldn't be accelerated. I'm curious which pool the service was submitting to, but I can't find the original post now.

Now you have some nodes that still contain the original transaction ignoring the new one and is there not a chance that it could still get minded?

It's possible that either transaction could be confirmed, depending which pools mine subsequent blocks. I've seen two transactions spending the same inputs, where the lower fee transaction got confirmed (and the higher fee transaction got discarded by the network). Pools have transaction priority mechanisms that we'll never be privy to, and users on the network can always submit the lower fee RBF transaction to an accelerator service. In that case, fees aren't everything.
93  Alternate cryptocurrencies / Altcoin Discussion / Re: Tether: help? on: November 29, 2017, 11:47:24 PM
I go into my Bittrex account, and decide to convert my USDT into ETH through changelly.com, but I find out my account is not verified so I can't send shit. I did basic verification, I even used my real infos (which I'm not really happy about) and like I expected, they didn't find anything in the records as I am not a US Citizen. They invite me to do an enhanced verification, which is even worse than inserting your real infos, they even ask you to send them a selfie (fucking gay right?), I waited a day and sent them everything. After 10 minutes, they reply to me with "Name Mismatch", I look up the same error on internet and looks like it's a common issue so I email support as suggested. After something like a week still no reply, I log into my Bittrex account and apparently I was upgraded to basic user even thought I still get the same error when I click on basic verification, but apparently now I can withdraw 0.4 BTC which is perfect.

There's hundreds of people complaining about similar issues. It seemed like one of the common threads was that Basic Verification stopped working for people who are not US citizens. It's interesting that you had your withdrawal limit increased to that of a Basic account, given the name mismatch error.

I go on changelly, and as if I wasn't unlucky enough, I find out THEY FUCKING REMOVED USDT. So I go on shapeshift, I select usdt, and guess what? TEMPORARILY UNAVAILABLE. You gotta be shittin me.
How do I go about this? What the heck do I even do now? $770 trashed in the bin I fucking knew it.

I don't understand. Why don't you just trade the USDT markets on Bittrex? I have the Bittrex:ETHUSDT chart open, and it's ticking away normally. Why do you need to involve Changelly or Shapeshift? USDT is always unavailable on Shapeshift, anyway. I've never seen it available once over the months that I've used their service. Not sure about Changelly.

Anyway, 1 USDT = $1.01 at the moment, so no reason to panic. I would be much more concerned about the status of your Bittrex account. The third party enhanced verification service is dodgy. Lots of people with locked accounts right now, unable to verify.
94  Economy / Exchanges / Re: transfer to Kraken but no confirmation on: November 29, 2017, 11:35:22 PM
hi there about Coinomi, I took this wallet as it has access to many coins.

what online wallets would you recommend? as I intend to invest in more coins vs just bitcoin, ether and lite in the future?i do have blockchain at moment?

I don't recommend any third party web wallets. You should control the software that signs/broadcasts transactions. I also dislike mobile wallets, especially closed-source wallets. Most use centralized validation and have very poor privacy, particularly multi-coin wallets.

As mentioned, there are Jaxx and Exodus, but I've seen reports of vulnerabilities in both. I immediately uninstalled the Jaxx wallet when I realized that you literally cannot encrypt the wallet with a passphrase. You get a 4-digit pin number. No thanks!

You should look into a hardware wallet like the Ledger Nano. They are integrating more altcoins everyday, including low cap altcoins. This is the most user-friendly and secure option for dealing with multiple currencies and internet-connected devices.
95  Economy / Exchanges / Re: transfer to Kraken but no confirmation on: November 29, 2017, 10:21:16 AM
I set up an account with Kraken today, at a level one only. I then transferred after my account with kraken was approved and verified

transfer as a deposit of Ether from my Wallet to Kraken

transaction on coinomi went through  and I used proper address, no mistakes

You're sure that you deposited to an ETH address, right? Post the tx hash ID from your transaction history, so we can confirm. For example, it should look like this: https://etherscan.io/tx/0x05f71e1b2cb4f03e547739db15d080fd30c989eda04d37ce6264c5686e0722c9

Coinomi apparently confuses some people into exchanging currencies before sending. I came across a thread where someone thought they were sending BTC, but they ended up sending USDT to a BTC address. This was problematic because the broker didn't support USDT.

After we confirm that the transaction actually happened on the ETH blockchain, the next step would be to confirm that the receiving address was actually your ETH deposit address at Kraken. A screenshot will do, but be careful to crop/black out any other account information before posting one. 

however no confirmation on email, nor nothing showed up in Kraken
been a few hours now and nothing

what is wrong?

It's possible that their node is not operating correctly and/or that this is just a delay. But it sounds like something went awry. I would really advise against using Coinomi. It's closed-source, and its Shapeshift/Changelly onboarding seems to confuse people. In a pinch, I much prefer https://www.myetherwallet.com. To circle back to your other thread, they checksum addresses....
96  Alternate cryptocurrencies / Altcoin Discussion / Re: Wrong Address in a buying transacation? on: November 29, 2017, 09:55:13 AM
I use a coinomi app as my crypto wallet. Today I made a purchase of some ether. after making the transacation which actually got approved and I got email on it. I realized I type in my Ether Wallet wrong
missed 2 letters. but yet transacation went through to some place

I did not receive my new coin though? did someone else get it? or what can I do if this happens

or is my money gone? forever?

This flaw has always been frustrating to me. Your money is gone, and you don't control the private keys that will let you access it. If you are sweeping private keys, typing is fine. No harm done if you screw up. If you are sending/receiving ETH, a typo can screw up everything.

With Ethereum, it's particularly important to copy/paste or use QR codes. Ethereum addresses don't have checksums (not natively anyway). There is EIP55, but it's a band-aid. if the counterparty hasn't implemented the checksum algos, it does nothing for you.

I wish they'd address it in one of their hard forks. I don't understand why they haven't. Maybe there is some complexity/technical problem that I don't understand.
97  Economy / Services / Re: Nexchange.io Signature Campaign (FULL) on: November 27, 2017, 10:47:16 PM
at least indicate if this campaign is active,,thanks

The manager of this campaign probably goes to this forum every once a month just to send an announcement that the payment was sent and then goes back to being offline again.

No, he logged on yesterday. He comes online all the time. To be fair, it was bad etiquette to announce that there were five openings, and then neglect to fill them:

We now have 5 more vacancies.

Regards,
O.

It's now been 3.5 weeks since that post, and he didn't accept anybody into the campaign. Meanwhile, many people have added the signature/avatar/personal message based on the aforementioned vacancies. These people are providing ostensibly free advertising.

I'm fine with campaign managers taking a few days to approve new applicants. But 3.5 weeks? That seems unacceptable. It almost seems deserving of a red asterisk on your chart, if only to warn people against joining for nothing.
98  Economy / Web Wallets / Re: Blockchain.info change adresses on: November 26, 2017, 09:42:21 PM
Is there any way to export bitcoin change adresses from blockchain.info?
I had biitcoin in a "change adress" during the last two bitcoin hard forks and I need to get its private key in order to use the btg and bcd stored in this adress. In my wallet in blockchain.info i can't even view the change adresses even if my btc is on one of them now.
I tried finding the adress from the recovery phrase of my wallet, but I can't find that specefic adress or any used change adress from the list of the adresses linked to my wallet.

It sounds like you had those coins there for a while, if you're referring to the Cash and Gold forks. Prior to the Bitcoin Cash fork, when were the coins last moved?

Is it possible that you were using the Blockchain.info legacy wallet at that time? In early or mid 2016 they rolled out HD wallets, but there was a period of time afterwards (several months) where you could still use the legacy wallet. If your coins were in legacy wallet change addresses, you will need to export them one-by-one. In that case, go to Settings > Addresses > Imported Bitcoin Addresses. To the right of each address is "More options" > Private key.
99  Economy / Exchanges / Re: WARNING: Bittrex has converted Legacy Accounts to New on: November 25, 2017, 11:45:39 PM
However, without any notification they have terminated their "legacy" accounts and converted them to "new" accounts with a 0 withdrawal limit.  While I am just a hobbyist and don't have a lot of BTC I find this very upsetting and unprofessional to have done this without any notification.

Worse, when I tried to do a Basic Verification (which is all I really need) it failed instantly.  This does not give a lot of confidence about their verification systems or service.

I did Basic Verification on a new account a few months back. They weren't able to verify my details through public records. But instead of rejecting the verification, they allowed me to simply verify my mobile phone number via SMS. Did they offer you this option, or is that gone too?

So if you don't have a verified account at Bittrex I would advise against depositing until you do.

I heard recently of multiple cases where people with "enhanced" verification still had their accounts disabled and reduced to "new" account status. Bittrex is definitely making lots of changes (KYC, disabling accounts, new minimum/stale order policies and supposed policies against "pump groups") and they've been doing so ever since BTC-e got shut down.

I can't tell if they are being directly pressured by regulators or law enforcement agencies, or if they are just scared and doing everything they can to more closely comply with existing regulations.
100  Economy / Speculation / Re: We are heading $9,000 next week? on: November 25, 2017, 11:16:19 PM
What'd you think people? Bitcoin now has reached new ATH or it can surpass $9,000 and already heading to $10,000 that quick?

We are in the parabolic stage of this uptrend. One might even say that we are in "blow off top" territory, but even so, we can still go significantly higher before this ends with a very significant bearish correction.

As such, I expect the speed of the rally to continue increasing. At this stage in a trend, I'd also expect volatility in both directions to be increasing, meaning that we can expect the bear traps to be increasingly fast and brutal. The lows at $5400 and the subsequent bounce are characteristic of what I mean.

I guess what I'm saying is, the difference between $9000 and $10,000 is now very small. Bitcoin can do that in a day now.
