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. However if you want a light wallet, you can just use Electrum. They are both open source.

Seems to me like you should just restart your computer and try again. If it doesn't work after an hour or two then delete the blockchain and resync again. As long as you keep your wallet, it ain't a big deal. You can use Electrum wallet until you are resynced if you need to send some bitcoins or something.

You should check out Greg Maxwell's talk on Youtube about confidential transactions.

I don't believe that would create any such value overflow problems. As a softfork this is allow transactions to be confidential, but you could still use old software with the non-confidential transactions and confidential ones would still be valid, this is done by miners agreeing that even tho according to the old protocol anyone can spend coins locked in this way, they will not accept transaction that don't offer extra proof. The bitcoins locked in these confidential transaction chains would be limited by old nodes as well that wouldn't be able to account for the extra coins, as for them they still see the same coins existing, just locked in a way that anyone can spend them.

The vulnerability you mentioned is very very old (2010) and really has nothing to do with this concept, so it is unlikely that the problem will be possible in any way if confidential transactions are implemented.

I am unfamiliar with the Bread wallet, but in most wallets you can go to something like "Receiving addresses" or something like that, where your wallet will give you a Bitcoin address that was generated by that wallet. Then you will need to go to your exchange and withdraw the funds (again unfamiliar with the exchanges), where you need to place your Bitcoin address where the exchange will send you your bitcoins.

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).

Practically no, there is not way. Sorry buddy, a rookie mistake. I assume you didn't actually use an online website and downloaded the code of the website instead and ran it locally. It would be insecure to use an online website hosted by someone else for this. But if by any chance you weren't careful enough and actually used an online website, I would email the owner of the website for a chance he keeps the logs and offer him a reward.

Perhaps this is something you should raise a Github issue on or create a topic on Bisq forum, that is usually used for support. Perhaps the devs will ask you to PM them some logs or something like that. You can find Bisq forum at https://bisq.community

Exactly. PoS can make a lot of problems. In PoW anyone can mine bitcoins and there will be always bitcoins that you can buy by selling your computing power, even when the block reward goes zero, you will still earn from mining fees. They would be just increasing the price of Bitcoin by not buying stuff with them.

Satoshi is hoarding a lot of coins and might not get to spend them while he is alive (if he still is). This is with best intentions. Holding Bitcoin is helping the network. Don't let years of government propaganda convince you that inflation is necessary and that you need to spend you money for the good of economy. This is just what rich folks that own big consumer companies want, it is not in your interest to do so.

Just hold bitcoins until you need to buy something and convince other people to do the same.

Sure, just take Bitcoin and hardcode difficulty to 1. That will make confirmations instant and there will be plenty of space in the blocks, so the fees will be low.
As you can see, this will make plenty of problems and you must ask yourself on how much security and stability you want to sacrifice for speed. Bitcoin was created to be what developers thought the best option. (10 minutes for one block on average)

Naravno da ce mu cena rasti, jer ne moze da opada osim ako ljudi ne pocnu da prodaju svoje bitkoine da bi kupili nesto drugo u masovnim kolicinama.
Pa ce i biti ljudi koji umiru i ostane im bitkoin zarobljen i izgube novcanike i tako dalje. Ocigledno je da kad nema inflacije da ce biti deflacija, ali zanemarljivo.

Kako mislis ko ce mu odredjivati cenu? Pa niko mu nikada nije odredjivao cenu, niti ce. Slobodno je trziste, odredjuje se samo.

Kao sto rekoh, previse ste zamislili buducnost slicnu sadasnjosti. Kada prestane da se bitkoin kopa, to ce biti za vise od 100 godina.
Bitkoin ce se idalje kopati, ali ce rudari uzimati provizije od transakcija kao glavni doprinos, to je uvek bio plan.
Nece bitkoini imati cenu, oni ce biti ono po cemu se cena odredjuje, to ce biti valuta, globalna stabilna valuta.

Broj ljudi ce da raste, inflacija nece biti dovoljna da to izbalansira, pa ce vredeti da cuvas novac, a ne ko sada da moras da ga stavljas u banku, i to opet ga izgubis iako dobijes kamatu. To je tako namerno. To nije problem, to mu je snaga.

Tako da bitkoin nikada nece "presusiti", uvek ce ga biti dok ga ljudi koriste. Uvek ces moci da rudaris dok god mozes da ubacis transakcije u svoj blok.

Of course Bitcoin isn't perfect yet, perhaps still best for international payments, but still not what it can be and that is currency.
Many people here claim it is not good as currency because the price is not stable or the fees are too high, but neither of these things are here to stay.
Some here say that no one will spend bitcoins, because their value rises, which makes no sense at all, even if it was true forever.

Lightning network is being tested so soon fees will be almost non-existent and transactions will be instant.

Price is not stable because it grows due to higher adoption and then it has correction. Once it reaches high worldwide adoption, there will be no increase in the value as the demand would stay the same. Fiat will be less stable then Bitcoin, because it has higher inflation and it depends on politics, Bitcoin is preprogrammed about it's monetary policy and highly predictable supply.

Once people adopt it and most of people use it, there will be no increase in price so it would be useless as a store of value, but it will still be the best system out there to be used as a payment method.

AI and ML helps absolutely nothing currently in terms of hacking. The increase in hacks is due to increase in dependence on technology and lack of quality software.

Mislim da malo gresite kada zamisljate Bitkoin kao nesto sto je sada. Jednog dana ljudi nece ulaziti u kriptovalute, vec ce biti placeni u njima.
Nece gledati koje postoje, a koje ne. Sta koja daje. Bice stvar drustvenog dogovora. Sta ce se koristiti za valutu.

Mogu ja ovde da pricam milion problema koje ima Ether i zasto nikad nece pratiti Bitkoin u njegovom rastu, ne do kraja.
Ljudi nece ulaziti u kriptovalute da zarade na kopanju ili investiciji, koristice ih zato sto im treba. Da bi kupili hranu i platili racune i zato ce raditi za njih.

Sto se stabilnosti tice, razmisljaj na duze staze. Stabilnost ce doci kada se masovno bude koristio Bitkoin, to je ocigledno. Sada je nestablinost uglavnom samo nagli rast pri rastu Bitkoin korisnika i onda korekcija. Kada nece biti toliko novih korisnika, cena ce biti stabilna.

Ove stvari koje sada vidite u kripto svetu nisu sustinska karakteristika kripto valuta, nego karakteristika neceg novog.
Zato ljudi ga i zovu bubble, zato sto se ovo desava svaki put kada se nesto novo izmisli sto je korisno ili ne.
Desilo se za Internet, desilo se i ovde. Ali Internet je uvek rastao, jer je vredeo. Sajtovi si pukli (dot com bubble), ali Internet je ostao (amazon je isto ostao i sada je jedan od najvecih). Posebne karakteristike kripto valuta je ono sto ja tvrdim da ce da odrzi cenu Bitkoinu, ali nece i altkoinovima.

Bitkoin zahteva bubble, on je tako napravljen. Jer Bitkoin vredi samo kada ga dosta ljudi koristi, slicno kao Internet, ali ne i kao neki sajt na Internetu.
Tako da kako bubble raste, sustinska vrednost takodje raste, to je karakteristika mreza i valuta generalno, a Bitkoin je oboje.

You can also use a bank and never bother with Bitcoin in the first place If you don't control your private keys, you don't own any bitcoin.


Who's to say that year ago the fees were normal? Fees grow exponentially as you approach the maximum capacity of the network. There needs to always be space for more transactions, that is when you can see fees as stable.

I think Bitcoin will prevail as a payment method. A lot of people are focusing on Bitcoin price, but Bitcoin is still a good technology. It is the best system out there for payment transactions and store of value (in other words, currency).

You don't need to register, you just need a secret number to receive bitcoins. A lot easier then other payment methods.
You own your money and no government can take it from you with inflation or a failure of banks.
It is decentralized and open source, so it is secure and private. Security of every Bitcoin transaction is independent and of each other and at highest level.
In other payment methods, you hack one entity and you hacked all their users. (Paypal just had a breach this Friday).

It is simply objectively the best. Fairest, fastest, easiest to use, private and most secure. It isn't just the best, it is 10 times better then anything out there.

Not possible. You can make it cheaper by using segwit and bundling transactions together, but don't expect to get an amazing discount.
This is a issue in Bitcoin right now and we all hope that Lighting Network will fix this, at least for long enough until Bitcoin reaches high world-wide adoption.

Cena jednog tokena ne znaci nista. Taj token mozda jeste skuplji ali ih onda sigurno ima manje. Bitkoina ima 21 milion, 42 koina pretpostavljam da ima samo 42 Ono sto se gleda tu je sto ovi zovu market cap. A to je ukupna vrednost svih koinova (tokena) na trzistu.
Bitkoin ima veci market cap nego svi altkoini zajedno, a kako se bude vise koristio pretpostavljam da ce samo da raste.

In a world full of idiots and religious lunatics, should it really be illegal to punch people in the face?
Should it be illegal to stab loud drunk people in the streets? What about those people who call your house to advertise something?
Or store clerks with a shitty attitude? I don't know, seems pretty logical to me that it should be legal to strangle any baby that is screaming in the airplane.
It is like they are asking for it.

I would say it is soap and toilet paper.
If you only knew what life was in ancient Rome like...I would take no wheels, no fire and no electricity any day over toilet paper and soap.

Any open source wallet will allow you set your own fees, so there is no cheapest. You can pay 0% if you wish, it is just that the miners will likely never confirm it and as a result other Bitcoin nodes won't even relay your transaction if it is bellow certain amount.

Electrum is a popular light weight open source wallet and Bitcoin Core is a backbone of the entire network which stores, validates and replays all transaction on the network.
