481  Alternate cryptocurrencies / Altcoin Discussion / Re: What happened to NEO? on: August 12, 2018, 02:30:32 PM
If we leave aside the current bearish sentiment of the market, NEO seems to have additional problems. The community is currently caught up in a debate as to whether their NEO token should remain indivisible or not.

They are about to release the next version of the NEO software, and some team members, including one of their co-founders are pushing forward the idea of NEO being divisible, which could solve governance problem and generally inactive token holders.

The other issue that could be solved with this move is price related. If the price rises again to $160, a divisible NEO could be more accessible to small investors.

I don't know to what extent the community is polarized with respect to this move, but it will be interesting to see how they deal with this dilemma.

Take a look at the following link:

https://github.com/vergecurrency/VERGE/issues/524

The guy seems to have a similar problem to yours (cx_freeze error). Maybe the discussion there could help you.

havnt changed or edit any files only keep trying to connect to different servers whats my options? a different pc?
If you still have the Electrum seed (12- or 24-word phrase), then you can try a different PC. Or you can even try to reinstall Electrum on your current PC and import the seed (again, before doing that, make sure that you still have the seed written somewhere).

I suggest to try to follow the campaigns of these anti-spam bounty managers.
OP won't be accepted in any anti-spam campaign.
Right. I see what you mean, and my advice is useless to him. I should have checked his posts before replying to his thread.
484  Other / Meta / Re: Real Bounty Campaign VS Fake or Scam on: August 11, 2018, 05:30:55 PM
It's not always easy to tell what campaign is real and what is fake. Especially at the beginning they may look the same. And it is not up to the admin to estimate the validity of the campaigns. For example, if Ethereum doesn't care what kind of ERC-20 tokens run on its blockchain, what right has this forum to do so?

In addition, from what I've seen, there are very active users of this forum who try to fight scam actively. Just take a look at the Scam Accusations board, and you will see what I mean. But, at the end of the day, each participant has to do their due diligence before joining a campaign as well.

Another useful thing is to pay attention to the campaign's manager. If the manager is prominent member of the community, your chances of getting paid at the end are considerably higher.

I suggest to try to follow the campaigns of these anti-spam bounty managers.

Let's think together, how can we protect our money in the future, so that hackers had no chance to steal them? Can there be any wallets?
You can install metamask, which generally offers better protection than MEW:

but prior to that, you have to make sure that your computer is virus free (either thorough cleaning or brand new OS installation).
487  Bitcoin / Development & Technical Discussion / Re: Consolidating Unspent Transaction Outputs on: August 06, 2018, 04:16:52 PM
I do. Every now and then, I consolidate the UTXOs into a single one with a very small fee. I don't need to use it anytime soon and it has opt-in RBF anyways.
Consolidating your inputs while fees are low should definitely not be ignored, especially if you are receiving a lot of small payments.
1 sat/B transactions do get confirmed pretty quick currently. But make sure to have the RBF-flag set to increase the fee in case of an unexpected spam attack.
Never crossed my mind actually. Great tip. It makes sense that if I'm consolidating, then I'm not in a hurry (to make the transaction) so I can afford to pay low fee. And the "replace by fee" flag should be set just in case.

The UTXO database isn't the largest concern since its still relatively manageable. Its roughly 2.6GB right now and the blockchain itself is more than 10 times bigger.
Somehow I thought the database was bigger. For today's standards, it is very acceptable even if it's entirely loaded into the RAM.

RAM is non-persistent memory. Each data has to be stored on the hard drive and has to be loaded into the RAM while reading/writing to it.
I see. So, should I assume that normal nodes keep the data on the hard drive to be loaded when needed to make validations, while miner nodes try to have it in the RAM most of the time to be as fast as possible in their calculations?

I usually only consolidate unspent outputs funding the same address... In any case I never consolidate unspent outputs funding "anonymous" addresses together with unspent outputs funding "public, known" addresses.
That's a great point to keep the anonymous addresses separate from the publicly known addresses.

If privacy is a concern with address association, another option is to use a consolidation spend to another service's wallet: an exchange you trust when you want to buy some other coins or simply when you want to trade/sell your Bitcoin? Or even to a mixing service - Then, not only do you consolidate, when you withdraw back to your wallet, it comes from a completely unrelated wallet (at least, in the case of a good mixer, this is what should happen).
That's another great tip. Also, never really thought of that, but it makes good sense.

Personally, for low-privacy wallets, I use every actual transaction opportunity I can to consolidate, since it's a tx I need to make anyway and the fees don't cost that much more just to get 3 or 4 extra inputs in. I imagine people seeing that wallet could analyse my spending habits Wink
Well, as a newbie who doesn't hold much bitcoins, I'm not really concerned of privacy or anonymity, but it is good to have an idea of how experienced bitcoiners are managing their bitcoins.

Thank you all for the great tips. 

488  Bitcoin / Development & Technical Discussion / Consolidating Unspent Transaction Outputs on: August 06, 2018, 01:15:20 PM
I was wondering what's your way of dealing with multiple income that you receive in your bitcoin wallet.

Specifically, how do you manage your wallet in case it contains a lot of smaller unspent transaction outputs (UTXO)?
This could happen if, for example, you are getting paid smaller sums, regularly sent to the same or different bitcoin
addresses you control. Do you make an effort to consolidate these smaller values into a big one sent to
a single UTXO that would hold the total value of your coins?

You could consolidate your funds, for instance, during times when the transaction fees are low and the network is
not congested. What do you think, is there any advantage to this, other than possibly having to pay lower transaction
fees (fewer inputs, smaller transaction size) once you decide to spend the funds in the future.

In fact, for the global UTXO database, an obvious advantage would be reducing its size, becaue you are spending
multiple transaction outputs and consolidating them into a single one. It wouldn't make a huge impact if only you
were doing this, but if the majority of users adopted this practice, maybe it could reduce the size of the UTXO database?

By the way, I'm not sure where the UTXO database is stored. Is it stored on a hard drive, or in the computer's RAM?
I suppose the miners should store it in the RAM (they have to be fast in validating the transactions). Either way, I guess
this practice could save some space.

I can think of one disadvantage too: probably you are leaving a bigger fingerprint that could weaken your
anonymity and privacy. Because, by consolidating into a single UTXO, you are connecting addresses (payments) that
have been potentially unrelated before.

What are your thoughts?
489  Economy / Trading Discussion / Re: What is your trading style? on: August 05, 2018, 05:06:21 PM
Up until now, I have been trying to be a trend reversal trader.   I mostly try and use RSI divergence on various timeframes (however prefer 4h), as well as using the MACD and the histogram as complimentary tools.
I've tried to use RSI divergence in combination with other trading indicators, but with little success. When you learn how divergence works, the lessons usually show you examples in hindsight. When you try to apply this knowledge in practice, it's not so easy to identify these signals on a "live" chart. As someone already mentioned in the discussion above, these trading indicators don't really work so well in the crypto markets. They originate from Forex trading, which is a much more regulated domain, without huge pump and dump events. At the end of the day, for me at least, it all comes down to instinct, trying to buy cheap and sell when the price is up.
490  Alternate cryptocurrencies / Mining (Altcoins) / Re: Whats is best option for me - auto changing algo mining os like nicehash on: August 05, 2018, 04:43:59 PM
I am searching for mining os. I dont think that Windows can do it so probably it will be linux.
I've never used linux for mining, but I could imagine that scripting is way easier in any linux OS vs any Windows OS. However, I'm not sure how good and how optimized the Linux GPU drivers are, and generally how good the manufacturer's support is. If you are a newbie, this may pose a problem.

Also, I have no idea how good the linux overclocking utilities are. Is there an equivalent to msi afterburner?

It might be worth checking specialized linux-based OS, such as simplemining and similar solutions.
491  Economy / Trading Discussion / Re: At what point can we say a coin has mooned? on: August 05, 2018, 03:00:40 PM
Going to the moon is to describe the linear increase in a short time so that the vertical line "Intersection of time and price" is as long as the moon's distance from the earth.
This is true of course, but there is one important additional requirement. This huge increase has to be maintained. Too often I've seen an equally steep decline back to earth short after the "moon landing".

We are trying to grow the community for IlumX in popularity so it can be listed on exchanges.
Your coin doesn't have to be ultra popular to be listed on an exchange. Last time I checked, most exchanges require to be paid in order to list a new coin. But, sure, if you are targeting the bigger and more important exchanges, than you also need popularity.

You just need to do a google search. There are plenty VPS providers that offer DDoS mitigation on top of their normal packages. From what I can see, the prices depend on the attack traffic.

Nice guide. I used to mine shield with the X17 algo and ccminer (if I remember correctly). I didn't know they incorporated x16s as well. Is it a recent move to include the x16s ASIC resistant algorithm?
497  Economy / Trading Discussion / Re: Can BITCOIN may cross ATH in 2018 ?? on: August 04, 2018, 01:30:14 PM
That's anybody's guess. IMO, depending on a number of factors, bitcoin could reach a new ATH at the beginning of 2019. But with these huge imbalances between supply and demand, you can never be sure. What one can be sure of, is that bitcoin (as a store of value), will continue to attract investors and capital. This means that in the long run, bitcoin will grow several orders of magnitude over the 2018's ATH. Even many financial experts are bullish when it comes to this long term future of bitcoin. They speak of price predictions in the range between $100,000 and $1,000,000 within the next couple of decades.
498  Economy / Trading Discussion / Re: Binance Founder, Zhao Changpeng Interview! on: August 04, 2018, 12:37:50 PM
This is higher than the same quarterly profit of Deutsche Bank, which has 148 branches and more than 100,000 employees.
Anyone has an estimate as to how many employees Binance has? I know that you cannot really compare a bank with a crypto exchange, but it would be interesting to contrast the numbers.
499  Bitcoin / Development & Technical Discussion / Re: Explain SHA 256 Algorithm on: August 04, 2018, 07:01:43 AM
And i have another question why bitcoin uses double SHA256,and how does double SHA 256 compared to normal SHA256 exactly work?
This is an old dilemma as to why exactly Satoshi used double SHA256. It has likely to do with preventing possible length extension attacks:

https://crypto.stackexchange.com/questions/779/hashing-or-encrypting-twice-to-increase-security/884#884

Also check out this BCT thread devoted to this subject:

https://bitcointalk.org/index.php?topic=45456.0

So is it impossible to hack double SHA 256 ? because Sha 1 was tamper proof too until someone proved they were wrong.How many years can we expect double SHA256 will be reliable ?.And thanks for providing the link of thread let me have a look at it.
It has nothing to do with hacking SHA-256 (probably by hacking in your post you mean brute force attack ). The kind of attack that this double hash prevents is called length extension attack and it is something different from brute force attack. You can read more about the way this attack is done, for example, here.
500  Bitcoin / Press / Re: [2018-08-03] Bitcoin & Cryptos Not Real Money - Dutch Central Bank on: August 03, 2018, 05:10:45 PM
This is a quote from the linked article, something a Dutch Central Bank official had apparently stated:

Quote
“If something wants to be treated as money, you have to be able to spend, save and calculate with it.”

I find this laughable and it shows how little understanding these people have of bitcoin. Because you can clearly spend bitcoin, save bitcoin, and calculate with it!
