381  Economy / Service Discussion / Re: Nicehash, exit scam? on: December 06, 2017, 11:31:06 PM
They have been hacked and lost huge amount of Bitcoins https://bitcointalk.org/index.php?topic=2537342.0  They messed up big time. All of investors are screwed up. They have weak security that why hacker stole funds from them. I don't think nicehash will be able to recover that huge amount. This is bad. They've been down for many hours now or even a day now. They said it will open soon. But i don't think they will be back. This is their exit. This is why i don't trust cloudmining. It's a shady business. 

there is no way they can recover from this. and i find their announcement very disturbing. if i am reading this correctly, they kept most or all of their BTC in a hot wallet. what kind of legitimate operation stores thousands of BTC on an online server in this day and age?

for that reason, it appears to be an exit scam. they are trying to appear incompetent to make off with millions of dollars and go live on an island somewhere. this is the classic exit scam formula we have come to recognize in this space.

I think they want to perform BTC-e's trick by saying some coins and money lost forever. So offer us taking some percents of our balance and be satisfy! After that they will do their business by new brand.

i don't think it's the same as BTC-e. in that case, the US government immediately issued a press release about indicting BTC-e and arresting one of its alleged owners. i don't think BTC-e was an exit scam at all, and i was pleasantly surprised when they partially refunded customers. they've also refunded ~10% of the debt tokens they issued to cover the losses.

I agree that it looks kinda fishy to me. Coming from a group of people that have literally been re-writing mining software, which is no easy task, you would think that they would be competent enough to have good security.

Reading all this negative comments with high ranks is discouraging. I have planned to test Bittrex next week but it all change now. Thanks for this guys and I think it’s better be aware of this problem and those sweet propaganda machine should always be observe before doing that is regrettable in the end. I’m not a good trader so hearing or learning from experienced trader is always my priority.
I have nothing good to say about them anymore.
They have:
  • High static BTC withdraw fee (0.001 ~= $13)
  • Bad customer support
  • Requires verification to withdraw, but not to deposit (seriously??)
  • Higher minimum trade requirement

I used to use them, but they just got worse and worse until these changes pushed me away from them.
383  Bitcoin / Hardware wallets / Re: Hardware wallet - Claiming forked currencies on: December 06, 2017, 11:24:14 PM
There are quite a few reasons for ledger/trezor not to support every forked shitcoin, but thats a different story.
With ledger/trezor you will always be able to claim your coins by importing the BIP39 mnemonic seed (12/24 word phrase) into another compatible wallet,
and use the generated private keys to 'claim' your forked coins in their appropriate wallet.

But this should be done carefully. After typing your seed into your pc you should regard your wallet as compromised.
So to be on the safe side, first send your BTC to a new wallet, then import your old priv keys to the fork-coin-wallet software.

Important note that if a coin doesn't plan on supporting replay protection (like Segwit2x was about to) then sending your BTC out of your wallet first without splitting it would result in the loss of your other coins at worst, and at best you just moved both coins to a different address.
384  Economy / Gambling / Re: How many of these sites are legal? on: December 06, 2017, 11:21:53 PM
If you explain us what you mean with correct licenses, I could help you better? Based on my experience, there are no correct licenses! The license itself might be correct from a juridical point of view in some cases, but how does this help you if you get the runaround when help is needed?

Unlike more important is that the operator is since a while on the market and works correct.

I think you might find a few sites licensed out of a small country like Curacao for example, but honestly it doesn't mean much. What people should be looking for in Bitcoin sites (provable fairness) is different than what people should be looking for in regular casinos (regulation & licensing).

Ah, I misread. Self-exclusion makes sense and I'll make sure we offer a seamless way to do so in a future update. There is still the issue of how easy it is to create an account, and I don't want to lock-away player funds even if they want it so in case they end up needing it for another purpose.

You don't need to lock player funds from withdraw, just lock the games from being played.
386  Bitcoin / Bitcoin Technical Support / Re: Not seeing balance of segwit address in Bitcoin Core on: December 06, 2017, 11:17:59 PM
As for your last point, I wouldn't worry about it. I think it's likely that in the future, the wallet will be able to support segwit and will scan those addresses automatically, however once Bitcoin Core gains full segwit support they might use a different derivation path for segwit addresses. In that case, it would be best to make a new wallet and transfer all your coins over.

As for ImportPrunedFunds, here's a note that's on the command
Quote
The end-user is responsible to import additional transactions that subsequently spend the imported outputs or rescan after the point in the blockchain the transaction is included.
So after you spend it, the coins leaving the wallet might not be displayed, and if so you'll have to use ImportPrunedFunds on the outgoing tx also. ImportPrunedFunds takes two strings as arguments, the first being the raw tx and the second being the proof.
GetTxOutProof takes an array of txid strings as it's first argument and has an option second argument of the block to look in. What I would try using is the second command you typed in your image, but get rid of the block part, using just gettxoutproof ["yourtxhere"].
387  Economy / Gambling / Re: ⚖️ Crypto Gambling Foundation ⚖️ - Funding up to 5 BTC to new gambling startups on: December 06, 2017, 05:47:03 PM
...
All approved websites for funding will automatically become junior members of the foundation. This is not a fully verified operator as you will need at least 6 months of legitimate operation in order to become eligible.

According to your website, Bustadice is among the fully verified operators:
https://cryptogambling.org/

However, Bustadice was launched at the end of September and therefore has not even remotely been operating legitimately
for 6 months. I don´t think they are a scam, because of the people involved and their track record. Yet this is
basically a violation of your acceptance criterias for fully verified operators.

Regarding the actual topic of this thread:
Great idea, I really think provably fair gaming is one of the big innovations that has arisen alongside cryptocurrencies
and I welcome every approach to increase awareness for this innovation.



What problems do you have with bustadice? I've looked at their site a few times and run a chat bot for it, and nothing concerned me.

EDIT: Ah, you're saying they haven't been operating for 6 months, nevermind.
388  Bitcoin / Hardware wallets / Re: Use two nano s ledger wallets, separate wallet accounts? on: December 06, 2017, 05:45:17 PM
In the Bitcoin App (Chrome) you are also able to create several accounts. So, for your use case you do not have to buy a 2nd Ledger.

Mentioned here: https://www.ledgerwallet.com/apps/bitcoin
MULTI-ACCOUNT
All your BIP 44 Bitcoin accounts are managed within a unique interface, where you can send and receive, on-demand, in real-time.


But I like the idea of using two Nanos as they will be less used, less likely for hardware failure, and two different pins, and set ups, and seeds.
And I will spread the risk if something goes wrong with one of them, losing the seed, etc...


I wouldn't get a second ledger, you're just wasting money at that point. You might be interested in the plausible deniability options the Nano S offers. You should have a paper backup of your seed on the card that came with it anyways, so you don't need another device just to store your seed again. Even if your device breaks, if you still have the seed backed up (which you should), you can recover your funds without buying another device by importing it into a supporting wallet (source).


I have a seed card, but I don't want to store all my coins in one account with one seed. I want to spread out the risk.

So, is it possible to use two Nano S Ledgers with two separate accounts?



Yes it's possible, but there really isn't any reason to it. I suppose if you're really paranoid you can put them in different physical locations, but seeds are uncrackable, people can't just guess them.
389  Economy / Service Discussion / Re: BTC.com wallet shit Uh-oh, Your IP has been blocked. on: December 06, 2017, 01:31:08 PM
You should think about restarting your wireless router, that might set a new IP address, and you can visit BTC.com without a barrier.
If anything, resetting their modem would do that, not their router, but it's very likely they'll just end up with the same IP. I would either contact them, or use a VPN, or go somewhere else (cafe, library) where you could use a different IP.
Its possible to pass through by resetting your modem because it would really have an other mac  but if it doesnt work out then the last resort would be using VPN because this is the common thing that been used when it comes on blockage of IP because of some restriction but quiet odd why they are really strict.
Resetting your modem will not change your/it's mac address, and your mac address doesn't matter anyways because the online service can't see it.
390  Bitcoin / Electrum / Re: Address gap on: December 06, 2017, 01:25:22 PM
Typically you can use your xpub key generated from your seed to generate addresses and not rely on electrum to provide those addresses.
391  Bitcoin / Hardware wallets / Re: Is Ledger Nano S REALLY SAFE ?? Best Hardware Wallet ? on: December 06, 2017, 01:16:49 PM
Hello,
I did just buy a Nano Ledger S from eBay, from this seller : https://www.ebay.co.uk/itm/Ledger-Nano-S-CryptoCurrency-Hardware-Wallet-Bitcoin-Official-Distributor-UK/263120752907?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

If you look on https://www.ledgerwallet.com/retailers the seller from eBay, I purchased from is an authorised reseller. Also they have a online store: https://smoothbuying.com

The only reason I brought from eBay is because it is next day delivery for me, and I get no hassle returns if needed.



As long as it's an authorised reseller, i wouldn't worry to much... I bought a ledger HW.1 and a ledger nano S, and IIRC, the boxes were packaged in plastic, and if memory serves me right, at least one of them had a security seal (on the box). To be honest, i bought both devices when they first hit the market, so it has been a while since i did an official "unboxing". Anyways, if you use the official bootable usb image to initialise your ledger, and you make sure it has the latest firmware from ledger, and use the official ledger chrome plugin to open the wallet for the first time, i think you're very close to being 99,99% safe Wink

The ledger team even has an online guide for opening the case and checking that the hardware hasn't been tampered with.

Ledger Nano S have Anti-Tampering Seal but is highly recommended to buy from an authorised seller (eBay seller could open brand new Ledger and write down private keys then sell and take your funds in future)

This is not true. The wallet does not come with a tamper proof seal, as it is not required. The hardware checks itself every boot. See their support website here. An eBay seller could not write down your private key as long as you initialize your device before using it, generating a new set of keys.
394  Economy / Gambling / Re: 🔶 YOLOdice.com 🔶 FAST play/invest, maximum transparency, distributing BTG now on: December 05, 2017, 07:08:53 PM
Hi everyone!

There are some important changes coming to the leveling system that will hopefully make the sistem independent of the crazy BTC/USD price.

Anyway, I pushed a few important changes today which may (or might not) affect your accounts:

1. You can get XP (eXperience Points) from the people that follow you. This is still true, but from now on followers that wagered 0.0001 BTC or less do not pass any XP. Earlier even players with nothing wagered passed minimal amounts of XP and we found users that were creating thousands of user accounts to take advantage of this fact.

2. I have reduced faucet amounts for the low-level accounts. The amounts were set when BTC/USD was way lower than it is now and we had to make these amounts a bit more reasonable again.

Cheers,
Ethan

so,the actual amount of XP we had is not going to change? sometimes we don't see who is following us
at least I,frankly,was pretty oblivious to the fact that I had any followers at all,haha
as for the faucet size-all of the main dice sites have reduced the faucet and its pretty much unavoidable
since the price went four times up in a matter of three months
It's likely your total amount of XP will change. I lost a chunk when these changes were made.

396  Economy / Service Discussion / Re: Are Bitcoin services trustable? on: December 05, 2017, 04:24:01 AM
Typically if I'm about to use a new service, I:
  • Google their name and check for negative experiences
  • Look for a bitcointalk thread, and see if people with issues are posting on it
and anything else that I might think of, including just asking people in chat rooms. I'd stay far away from new services unless you know the creator/owner.
397  Economy / Speculation / Re: Is 50% correction on BTC possible? on: December 05, 2017, 04:21:40 AM
As a price correction due to the huge increase in price, I think 50% would be too much but not impossible; probably 20-30% decrease would be more realistic in my opinion. A 50% decrease in price isn't impossible though. It's only going to take a huge FUD spree or one huge FUD issue to decrease the price in half.

I say 20-30% would be the lowest that bitcoin price can get. Bitcoin has already gained trust from most investors, that a minor dip would mean a perfect buying time for them. Although I would agree that it isn't impossible to happen but for me its less likely. Yesterday, I saw the price going below $11K and I thought that this is the correction that we all have been waiting for, but look what happens, investors quickly jump on the opportunity and "panic buying" occurred pushing the price above 11K again.

That's what I think. I think we've seen a huge change in how people think about the price since a few years ago. People aren't as ready to smash the sell button when it drops a bit, instead there's more people with the mentality that just makes them buy more. Add that to the huge institutional money coming in and honestly, bar huge technical issues or more dissent in the ranks like we had with 2x, I don't see those kinds of drops happening anymore.

Hello!

I've got a few coins on the side and I'd like to make them work.
Which gambling site do you advise me to invest in the bankroll?
There was a time when investing in casino bankrolls was very profitable, but I'm not sure if now it is that good. Also, if you were holding your Bitcoin since last year, I'm quite sure the results would have been much better than those provided by bankroll investments.
The thing about investing with Bitcoin is you make money when the price of Bitcoin goes up, and you also make money when your investment is profitable. They're not mutually exclusive.
399  Economy / Gambling / Re: ⚖️ Crypto Gambling Foundation ⚖️ - Fair Gambling For All on: December 04, 2017, 02:29:03 PM

This is a really cool idea! However, the issue with most provably fair systems -- is that you can only verify your own bets but not someone elses. A casino can just outright lie and there's no way for an independent party to know.  Embarrassed


So one possible idea, would be that the Crypto Gambling Foundation runs an "seed server" for each casino. Basically like the provably fair of bustadice.com ( https://gist.github.com/RHavar/285c295f7906e03369cd66580a1b5f45 ) which allows an independent party to verify the games. So it could be run by the Crypto Gambling Foundation.

But even then, there can still ambiguities. Like person says "I didn't request that withdrawal" and the casino is like "yeah you did".

The only way I can see to avoid that too, is just pure on-chain gambling games. (Like when I made pevpot: It was provably fair, non-repudiatable and immune to miners tampering. However, like most on-chain games it kind of sucked and people didn't actually like playing it).


Huh

Maybe somebody could be the first to leverage the just-released testnet of RSK to create Bitcoin smart contract gambling (https://www.rsk.co/)
400  Alternate cryptocurrencies / Altcoin Discussion / Re: Replay Protection BTC/BCC on: December 04, 2017, 02:20:09 PM
If you send the 0.1 BTC to some exchange without first splitting the coins, you will send BTC to the exchange, and then your transaction will be replayed on the BCH network, sending your BCH to the exchange as well. The problem is the address used by the exchange will not be set up to receive your BCH and you will not be credited with it.
This won't happen. Bitcoin Cash has replay protection.

If you send 0.1BTC, you will only send 0.1BTC;
If you use a Bitcoin Cash wallet and send 0.1 BCH, you will only send 0.1 BCH.

So no, you must split your BCH before attempting to send to a wallet that you don't control (especially an exchange, as they are the least likely to help you if you mess up).
Wrong again. You don't have to split your coins. If you do not confuse things and end up sending BCH to a BTC deposit address (or vise versa), you'll be fine.

My apologies, I was not aware that BCH had since required SIGHASH making it fully replay protected. Sorry for the confusion.
