I agree. It is good, it is just that you can still do this just as well without using the blockchain, so there is no need for that. There are other ways that still have all of these benefits and have no such downsides.
642  Bitcoin / Development & Technical Discussion / Re: Which types of wallet better for bitcoin? on: December 09, 2017, 03:12:32 PM
If you don't use core, then they aren't your Bitcoins. It's the same as money deposited in a fiat bank.

If you don't want to tie up 200Gb, then run a pruned node. You lose a few functions, but save a lot of drive space. If you haven't got the drive space available, then use an external SSD.

Good line. I don't have enough knowledge on BTC core too, so that's it. I wonder if that core is consuming a lot of data, and what is the requirements of the PC to run that?
I'm willing to download this.

It is a good line, very eye catching, but a bit incorrect Cheesy
As I said, you and only you still have full control of your coins when you are using Electrum and the drawback is not that big to be honest.
But it is a lot better to run Core for multiple reasons and security,privacy and helping the network is one of these.

Bitcoin Core takes few hundred MB of RAM and couple of tens of KB/s bandwith. The blockchain is around 170GB now, but it is always increasing so I would count around 200GB. However you can have a pruned node that can take as much as space as you define. It doesn't take much CPU power either and when it does it is usually small spikes every 10 minutes or so, when the new block comes.
It will just take some time to sync first time you start it as it needs to download and verify the entire blockchain. This is largely up to your CPU speed and it often take around a week.

In the latest version all of these fork coins were added. You can see this in the release notes at GitHub https://github.com/bisq-network/exchange/releases/tag/v0.6.1.
644  Bitcoin / Bitcoin Discussion / Re: What's safer than Telegram to discuss about Bitcoin/cryptos? on: December 08, 2017, 09:08:49 PM
Telegram is not open source, as far as I know, so their claims are meaningless.
Signal is open source, so I would suggest that.

Email is absolutely not safe, your ISP can read all of it usually or the mail server you are using can.
Email is great if you use PGP encryption, otherwise it is really bad for security on it's own.

Email is not really for chatting however, so an app like Signal that is open source and has end to end encryption that you can verify.
645  Bitcoin / Bitcoin Technical Support / Re: [QuestĦon] Should I upgrade my wallet (is from 2011) or no risks? on: December 08, 2017, 05:35:17 PM
Thanks.

Yeah if there is no risk, then I'll keep my wallet. (Maybe I'll encrypt it in the future but it's always on an external disk, I'm scared of encrypt it and have issue with the password or something like that).

Regarding the tx, I like to have the history of transactions, because if sometime the price shoots (like 1 BTC = 100k USD) and governs inspect money that comes from bitcoin in transactions, maybe all this transaction history counts as evidence for a tax inspection, etc.

But just to confirm there's no risk of having thousands of transactions in the future with this old wallet, right?  (Also thought about creating a new wallet and keep the old wallet for the history).

Oh, your wallet is not encrypted? Well that is a problem right there. That is the biggest point of failure in the whole thing. External disk will not save you always, it is better to have it encrypted.

As for the storing txs, blockcain does that for you. Just keeping your addresses would kind of have the same effect and you wouldn't risk of reaching some kind of limit if there is some.

I assume that if there was any problem with keeping too many transactions that your client will delete the old ones, but I doubt there would be an issue. It is not like they are taking up a lot of space or nothing.

I would create an encrypted wallet if I was you, but again, no real hurry. Might want to wait for more features and lower mining fees.
You should always keep your old wallet. There is no point in risking a loss of money to save up on practically no disk space at all.
646  Other / Off-topic / Re: How do you overcome radiation in frequently using devices? on: December 08, 2017, 05:04:13 PM
I recommend using special foil caps. Excellent protection against electromagnetic radiation. I even did this for a cat.

I also recommend you wearing a tin foil hat. Especially in public, so people know what they are dealing with Cheesy
Just messing with ya buddy. But seriously, you are being paranoid. It is a common misconception that electronic devices, even wireless devices, emit radiation.
Technically that is called a radiation, the electromagnetic radiation and that is why this misconception exists, but this is just nothing like the radioactive radiation.

You do know that magnets emit electromagnetic radiation as well, right? And the Earth. And the Sun. And actually light is also electromagnetic radiation.
And heat as well. And lightning of course. And all of these things emit far larger amounts of radiation of a lot higher frequency (imagine it as density if you wish).

Electronic devices use this "radiation" to communicate, so they use a bear minimum, just enough to be detectable.
While many things in universe use this type of radiation to mainly transfer energy. Like a stove, fireplace, sun, flashlight.
These things emit so much pure electromagnetic energy that you can sense it yourself, that it can even burn or hurt you.

Trust me, your cellphone uses such small amounts of electromagnetic radiation that you are hurting it more then it is you.
You heat up your phone while it basically has no effect on you. Bananas also are quite radioactive. far more then most things you will find around your house.
Smoke detectors have radioactive elements actually and can be quite dangerous if you are close enough for long enough.

But of course all of this is just ridiculous compared to smoking and polluted air. You are more hurt by that one time you smelled tobacco smoke then all of these things put together. The truth is, you are far more likely to be killed by obesity then anything else. It is just that people tend to try and distract themselves in order not to do any hard work, even if that work is just stop eating once you are full.

Not a device nor terrorism nor anything else will kill people as much as obesity, smoking and cars will every single day.
Society's main problem at this age is simply greed and nothing else. Everything else is simply amazing.
647  Other / Off-topic / Re: How can you move on? on: December 08, 2017, 04:47:10 PM
I never saw the weirdest poll in my life. "Who is the hardest part of moving on? Boy,Girl,Lesbian,Gay" Cheesy
Neither the question nor the answers make any sense independently, let along together.

Did you mean to ask something like "For whom it is the easiest to move on from a failed relationship" ?

Also lesbians are also gay, by definition, if I am not mistaken. Also Lesbians are also girls, so that makes no sense either.
Perhaps you meant to list "Straight boy, straight girl, gay boy, gay girl" ?
Also adding the "Other" option might include more people, so that would be ok as well, but maybe you didn't care about that part, so I have no issue with it.
648  Other / Politics & Society / Re: Banks afraid of cryptocurrency? on: December 08, 2017, 04:40:40 PM
Well banks don't just deal with payment methods, but with storing your money, giving you credits and etc. Bitcoin is a currency, not a bank.
However, banks will probably lose a bunch of power because of Bitcoin. Some directly, by not being able to get the government to print money for them.
Some indirectly, by people not storing their money in banks, since there is no inflation and no way for banks not to charge you a fee for storing your money for you. As well as the fact that it is easier to keep money more secure when it is just a number then physical paper and etc.
649  Bitcoin / Bitcoin Technical Support / Re: [QuestĦon] Should I upgrade my wallet (is from 2011) or no risks? on: December 08, 2017, 04:36:31 PM
In theory there should be no risk in using the old wallet. Structure of the wallet changed since then, but your client should have automatically upgrade it, as far as I know. So there should be no risks.

However, your wallet might be getting to big for your liking, with all those transactions and you might feel better if you transfer your funds to a new wallet. So you might want to do that eventually. But since the mining fees are a bit high now and you are probably in no hurry, you could wait and switch to a new wallet when perhaps more changes are made to the Bitcoin Core client and perhaps segwit gets implemented and lightning network.

So I wouldn't worry, but there is no reason not to do it eventually.
650  Bitcoin / Development & Technical Discussion / Re: There can be only one! ... or well, maybe a few on: December 08, 2017, 04:29:16 PM
You are exactly right. When Bitcoin was designed it was never meant there to be multiple blockchains and there really is no need for that.
There are obvious security problems with smaller blockchains. Even the biggest one can be in danger if all the smaller ones leave their own chain and attack the big one.

Optimally there would be only one blockchain for each PoW algorithm and there pretty much isn't any reason to use your own blockchain if you are just going to use an algorithm that is already in use, since you can always host your own chain on top of it and increase the security on both of them by doing so.

Most ICOs are horrible and useless and by most I mean practically all if not all. My advice is always to stick with Bitcoin as there is nothing else that really contributes anything useful.
651  Economy / Scam Accusations / Re: Westerncoin has hacked my account twice until now. on: December 08, 2017, 04:15:00 PM
You know what they say...Fool me once, shame on you, fool me twice, well... I get it tho, you thought your account was hacked by someone else. But you probably used similar password for other websites and they didn't get hacked, so it should have been a bit suspicious to you.

Also doing just a quick search it seems like it is a simple ponzi scheme. Really shouldn't trust people with your money when they offer you AMAZING profit for no work. The greed got you into this one friend and they are the devils that tricked you.
652  Bitcoin / Bitcoin Technical Support / Re: Transfer stock on: December 08, 2017, 04:02:28 PM
but can i Transfer to the same address or press the "request payment" batten there to speed up the process ?

You can try, but that would be a double spend and it will likely not be broadcasted by the nodes. You can wait 3 days for them to clear their mempool, but still not a guarantee. Request payment does nothing at the protocol level, it is just a nice feature for users.
653  Bitcoin / Development & Technical Discussion / Re: Which types of wallet better for bitcoin? on: December 08, 2017, 03:59:09 PM
If you are looking for a wallet on your PC, then Bitcoin Core is the best if you got around 200GB free space of hard drive to spare. It is most secure and helps the network.

If you don't use core, then they aren't your Bitcoins. It's the same as money deposited in a fiat bank.

If you don't want to tie up 200Gb, then run a pruned node. You lose a few functions, but save a lot of drive space. If you haven't got the drive space available, then use an external SSD.

I do always forget about the pruned nodes. They are a better choice, but I wouldn't go that far as to say that you don't control your bitcoins. For online wallets, yes, but for open source light wallets like Electrum, you still control your bitcoins. Now the state of the network and the balance is not fully to be trusted, but using Bitcoin Core all your connections might be compromised as well. Not the same as new blocks would have to follow the difficulty for a while, but still possible.
654  Bitcoin / Development & Technical Discussion / Re: How to integrate a global exchange into the blockchain itself on: December 08, 2017, 03:44:14 PM
This just seems like a way to give advertise that you are selling or buying bitcoin using a blockchain with a reputation system without even checking if trades even happened before reputation was given. In other words, reputation system could be abused.
Also it would be cheaper to just implement a P2P network for this, as none of it requires a blockchain. Blokchain is good for timestamps, to insure what went first, so double spends can't happen. It doesn't really bring anything here.

So it is an interesting idea, but wrong use of it. To be reasonable you need something that requires ordering to be done. Blockchain is good at ordering things in a decentralized way.

It is centralized in the sense that everyone can agree that this is bitcoin's main decentralized p2p exchange.  It doesn't rely on any dev's or websites that can be shut down or anything.  It allows wallets to encode functionality to auto-trade mined coins if the user wants.

The reputation system I am proposing is a #FB (feedback) message that only is valid if the wallet signing the feedback message was the one involved in the bitcoin transaction.  So it is unhackable.

Then it is just like web of trust, which again, has no need to be implemented in the blockchain. It is too expensive and has no added value.

I don't like clicking links from random people on the Internet, so I am just going to say that you might be interested in a project like Bisq (former Bitsquare). They use multisigs and security deposits to make decentralized exchange (fiat<->crypto trades as well).

I read about bisq.  It is complicated.  It requires traders, contributors and stakeholders, and defines several categories of high-trust bonded contributor roles such as maintainer, operator, and administrator.  Also it is an application and depending on which platform you use (especially mobile) it can be censored by app stores potentially.  Also it has it's own token, so you have an entire other cryptocurrency involved.

The main benefits of the op_return idea is that everyone that uses bitcoin can just use a block explorer in a "google" fashion to access the built in exchange.  Not only would it be a p2p decentralized un-censorable, crowdsourced (no dev's) and private no personal info required exchange, but it would be the revolution that would make bitcoin and the blockchain mainstream.  Everyone would understand and be able to use it without the need for any other software and bitcoin will be much more widely used.  Also it opens the possibility for automating exchanging of coins and fiat since wallets can rely on the op_return exchange as it will never be deprecated and isn't dependent on any dev's.

Bisq is a serious project so developing it in a decentralized way requires DAO and certain roles. All those roles tho are mostly outside of the app, there is no one that has access to all trades or something like that. The app is decentralized it is just that Bisq has a forum,website,developers and many more that it also wants to decentralize, so they take on the roles in the DAO. The cryptocurrency BSQ is optional and it is there just like a app coin that is there to fund the DAO, other then that, you can ignore it's existence. It also doesn't even exist on mobile, just PC and it's distribution is the same as Bitcoin Core for example. You can compile form source, download from Github, download from website, etc.

It is a cool idea that you have, I just think that you are not there yet. There is really no reason to put this on blockchain. Sure it would be cool, but expensive and unnecessary.

Moже ли ми неко објаснити ситуацију.
Мој друг је копао бтц на нице-хашу када је хакован али с обзиром да није досигао 0.1 бтц и пре датума исплате, сајт је хакован
те су његових 50$ колико је накопо нашло негде између. Значи није ништа било на ваулту а показивало му је око 50$ током
мајновања. Тешко ми и објаснити то али можда његови бтц нису "покрадени", јер није имао тада ништа у свом ваулту.
Односно како да му украду када то још није ископано. Он је обрађивао блокове и ископао би тек нешто са 0.1бтц у блоковима.
Па ме то збуњује.

Evo glupe ali jednostavne analogije .... To je kao kada krenes da radis u novoj kompaniji i radis npr 8 sati dnevno. Ako si placen 5e po satu to je 40e dnevno, ti mozes da "vidis svoj balans" ali plata "leze na racun" kada te poslodavac isplati. Znaci posle 10 dana ti si zaradio 400e ali ih i dalje nema na racunu ... recimo da se onda kompanja zatovri i ti izgubis svojih 400e koje si "zaradio".

Ako nije dostigao minimum pre datuma isplate, sve je to izgubljeno. Recimo da je datum za uispaltu je trebao da bude juce 12/7, tako da i da je imao minimum pre haka - tek bi juce kripto balans bio upucen ka njegovom btc novcaniku.

Bas tako. Majneri u poolovima su placeni za svoj rad, ne za to da li pronadju blok ili ne. Ako kompanija nema bitkoine da ti plati, onda ti i nece platiti.
656  Bitcoin / Bitcoin Technical Support / Re: Transfer stock on: December 07, 2017, 07:12:18 PM
Unless this was a RBF transaction, which I assume it is not, then you can't adjust the fee.
If you can contact the person who is receiving these bitcoins in this transaction, then you can instruct them to use CPFP method to bump up the fees and get it confirmed quicker.

There are some transaction acceleration services provided by miners as well.

This transaction will eventually confirm on it's own, but it could take weeks.

Bitcoin Core is the best if you got around 200GB free space of hard drive to spare. It is most secure and helps the network.

I can't believe i just read that.
In which universe is bitcoin core the most secure wallet? - definetly not in this one.
Every desktop wallet contains the huge risk of being vulnerable to malware of any kind.
Whether if its malware which is directly aimed at this wallet, waiting for you to unlock it just to steal all of your coins, or
if its the 'every-day-'malware (steal clipboard, copy/paste virus, search for wallet files, ... ) which is going around in the wild for quite some time now.

A desktop wallet in a safe environment is fine when storing some coins.. but for anything which exceedes a multiple of the price of a hardware wallet
i wouln't trust any desktop wallet (or any (especially) windows pc).

For everydays use:
Mobile wallet / Desktop Wallet

For anything above X coins (replace x with the amount of coins you would not want to lose to a stupid script kiddy because of a windows or java exploit):
Hardware or Paper wallet
Hardware wallets cost about 60$+ but are pretty handy for everydays usage and Paper wallets are basically free but not that handy when spending funds from them.

My post clearly starts with "If you are looking for a wallet on your PC, then" Cheesy
That is literally everything that is said before the quoted part, that you just sniped out and now the quote is out of context.
Context matters, bro. Don't snip out parts of my posts.

Bitcoin price pretty much goes only in one direction and that is up. At least in the long run.
In gambling you always lose if you play enough, the house only wins. In Bitcoin everyone wins and if you got into it more, you profited more.
If you bought bitcoins ever in your life and didn't sell them, you earned money. In gambling the opposite is most often true, it has to be, that is how it works.
660  Bitcoin / Development & Technical Discussion / Re: Bitcoin to Bitcoin Cash How Can I get it back? Wrong Transaction on: December 06, 2017, 04:31:42 PM
Do you control the Bitcoin Cash address you sent the coins to? Can you get a private key for that address?
If you can then you have nothing to worry about, if you can't then you will need to beg those who can.

Why do they allow it? Well perhaps the wallet you are using can't tell the difference. Bitcoin addresses and Bitcoin Cash addresses are identical, as it was a simple fork that kept the address format.
