8801  Bitcoin / Bitcoin Discussion / Re: Fidelity opens $0 commision trades, a possible alternative to dealing with abuse on: January 07, 2020, 11:51:39 AM
0 trading fees are not sustainable.
I prefer to pay a reasonable price and have a good service, like Binance.

If they are charging 0 on fees, they are probably going to offer a bad service soon.

I really hate withdrawal fees, which are usually very expensive for BTC. I wish there was an option to use 1 sat/byte transaction even if it too 2-3 days to complete in those exchanges....

You shouldn't be asking random strangers in the internet which stick to buy.
There is plenty good materials in the internet about how to analyze stocks in your own and choose the ones that fit your needs and investing style. There are also funds of stocks focused in dividends,  where you pay professionals to choose the stocks for you.
8803  Bitcoin / Legal / Re: GDPR Compliance in Europe is enough for users to trust with KYC info? on: January 06, 2020, 10:17:01 AM
Unless the user really need to make fiat transactions to your exchange,  there is no reason to do kyc (as anyone can make kyc free trades in binance)

So, there is only one good reason to trust my documents to someone.

Even though you are licensed now in Estonia, you can move to another country later which may be not regulated by gdpr compliance  (and our documents would be at risk).
Only time will make people trust your exchange

in contrast, it would be virtually impossible to impersonate vitalik buterin. the trade-off for ethereum is they forever have a "benevolent dictator". that trade-off isn't worth it IMO.

This is one of the things I find most amazing about bitcoin: The creator is totally anonymous.

Unlike Vitalik's Blockchain, where he is alive giving opinions and acting like a central planner, bitcoin is growing wildly without any central planner.

If satoshi was a real person, everything would be centralized on him.
8805  Bitcoin / Bitcoin Discussion / Re: Project Anastasia: Bitcoiners Against Identity Theft on: January 05, 2020, 11:30:22 PM
Welcome back nullius.

What I find ridiculous about all those fake satoshis is that they never prove to be him
 And it could be so easy.

Satoshi had many known public addresses.  Until someone just sign a message from one of those addresses, I.e. providing a cryptographic proof to be satoshi, they are just fake.

Calling them liars out loud isn't just like "feeding the troll"? I don't get how Craig got so much attention,  he even created the "real bitcoin cash". Lol
8806  Bitcoin / Bitcoin Discussion / Re: Google’s Censorship Of Cryptocurrencies Goes Way Beyond YouTube on: January 05, 2020, 11:20:39 PM
Yet cryptocurrency builders are facing traditional monopoly problems on the other side of the Google marketplace (Google and Facebook captured 63% of online ad spending in 2017 per a Wharton study) that do conform more closely to traditional anti-trust principles, facing elevated pricing on ads and pricing discrimination or even exclusion of service because there quite simply aren’t very many providers, if any, that can provide the services Google can with advertising beyond Facebook.

If the two coordinate to discriminate against a certain product category, that product category already faces headwinds to succeed. This may not be as politically fraught territory as lowering prices for the average American — but it can be a duopolistic and now anti-cryptocurrency element worth exploring.

What is interesting is that brave (and therefore cryptocurrencies) is competing to google in both browser and in the advertising industry .

Brave is for now still an unknown browser, used only by cryptocurrency enthusiasts.  But the idea is disruptive.a

Google may see bitcoin as a threat as well. Yesterday I saw a restaurant which accepted payments using Google pay. If the owner only knew that bitcoin is so much better.

The problem is the lack of regulations which is allowing google to do whatever it wants.
8807  Other / Beginners & Help / Re: Satoshi's own short summary is a great TL:DR of what Bitcoin is on: January 05, 2020, 09:11:53 PM
This forum is also an amazing place to collect more informal out the beginnings of bitcoin, as this forum is part of bitcoin history.

This thread is an interesting summary as well.

8808  Bitcoin / Bitcoin Technical Support / Re: Integrating Open Source Wallet on: January 05, 2020, 05:45:09 PM
I'm not a developer myself, so would have to hire one. I guess my concern was twofold:

1) The ability for a developer to act malicious and somehow put a backdoor in my app? Which seems unlikely if open source software is used?
2) The expense of developing & branding the actual open source within your own app. I'll be adding additional features, but that's the more straight forward part. So I guess it's not too difficult an undertaking in that case - to develop an open source non custodial wallet within your own app?

I am  not a developer neither. But I think your idea is pretty simple to do.

As long as you don't hold users private keys it is a non custodial wallet.
Adding new features is not  big deal, depending on the features ofc.

Many multicurrency wallets like coinomi and atomic wallet offers a few services  like an integrated exchange within the wallet. But those ones are closed source.
8809  Bitcoin / Development & Technical Discussion / Re: Will Bitcoin EVER have a bigger blocksize? Is there hope? on: January 05, 2020, 05:37:10 PM

Plus to have their cake and eat it too, they declare THEIR altcoin as the "real Bitcoin" because "Satoshi's Vision"/whitepaper.

That simply, doesn't how it works.

It got real crazy when bsv became the real bitcoin cash lol

It is pitiful to see the state of our ecosystem. Too many scammers , just trying to make quick money from people who are not very informed about the subject.

This whole fork drama is bad for bitcoin. But now both "real bitcoin" and "real bitcoin cash" look dead so we can move on.
8810  Local / Português (Portuguese) / Re: 64% do total de BTC em circulação não são movidos há mais de um ano! on: January 05, 2020, 05:30:09 PM


essa imagem ficou muito boa. Eu já conhecia essa ideia, a primeira vez q vi foi num post do Twitter em 2018. Infelizmente 2019 começou na mesma baixa de 2018 daí o gráfico não ficou tão bonito.

Quanto ao tópico principal:

Acredito que em breve o bifcoin irá realmente migrar para soluções de escalabilidade off Chain, como a lightning.

Em breve estaremos tendo transações praticamente gratuitas e instantâneas off Chain. E quem quiser transacionar grandes quantias fara on chain mesmo pagando uns centavos  e esperando 10min.

Isso na verdade foi previsto até pelo hal finney bem nos primórdios do btc.

8811  Economy / Web Wallets / Re: what derivation path coinbase is using? on: January 04, 2020, 10:02:45 PM
Huh

Coin base is not a wallet. Their "wallet " is not a wallet but a custodial service.
You don't have a seed for every user,  but mostly a derivation path for every single user or something like that.

It doesn't work like any other real wallet. You don't even have your private keys there.
8812  Bitcoin / Bitcoin Technical Support / Re: Integrating Open Source Wallet on: January 04, 2020, 09:58:07 PM
My question is building a non-custodial wallet using existing open source tech, how practical is this? I don't want to build a wallet from scratch if possible due to possible vulnerabilities etc, my budget is'nt big enough to make sure a custodian wallet is 100% air tight. So that's why I had the idea to build upon an existing widely used open source non - custodial wallet.



Technically custodial wallers are not wallets. All wallets should allow users to hold their private keys.  A wallet is an interface that allows you to sign transactions with the private key, just that.

Technically it is simple to use an open source wallet like electrum and modify its code for what you want. There are other good options like Samourai.
Do you want to support more coins? If you do, you can't do that with open source wallets (I don't know a single multicurrency open source wallef)
8813  Bitcoin / Electrum / Re: cant send BTC with electrum smart wallet connected to ledger device on: January 04, 2020, 08:33:10 PM
You can just follow this guide to use electrum and ledger nano. It is pretty much straight forward.

Realmente o que aconteceu tem nada a ver com   a ledger

O cara escreveu a seed no computador,  imprimiu usando o Wifi da impressora e baixou uma extensão maliciosa.

Se depois disso tdo ele ainda tiver algum saldo eu ficaria muito surpreso.
8815  Bitcoin / Bitcoin Discussion / Re: Affection of World War III to Bitcoin? on: January 04, 2020, 08:23:02 PM
I don't think things will escalate to a world war now.
But, anyway, the tensions might be good for btc.

A neutral currency in a polarized world. Well, it certainly has a lot of potential and uses.
Big players might do business with btc instead of usd for example
8816  Bitcoin / Bitcoin Discussion / Re: I took a photo of my wallet seed with a 35mm camera on: January 04, 2020, 03:09:10 PM
Is it a digital camera?
If it is, your seed is exposed and you should consider it compromised.

Just make a new seed and write it down on a piece of paper, like everyone do. And transfer your funds.

Hey, I was happy to find this
I am feeling lucky,  but I had a hard time finding a price which nobody already bet


My guess is 11451-11500
Bullish as always.

8819  Bitcoin / Development & Technical Discussion / Re: Will Bitcoin EVER have a bigger blocksize? Is there hope? on: January 04, 2020, 01:59:25 PM
BCH is not more 'centralized' ( what's the exact definition here, and what measures follows from such?)

Original BitCoin can already do a lot more than ripple , u just need to investigate it in its form/implementation of BSV.


Bch and bsv have nothing to do with bitcoin. Those are altcoins  which were forked from the bitcoin chain and those consensus rules were rejected by the community.

This is what decentralization means. Nobody is forced to follow a fork which changed the rules.

Roger Ver's chain and Faketoshi's chain are not decentralized because they are owned by people who can control their network.  They have a central planner. Community rejected their ideas and they decided to implement them anyway. That is what centralization is about.
8820  Bitcoin / Bitcoin Discussion / Re: Bitcoin cannot be decentralized if the Internet is centralized on: January 04, 2020, 06:32:18 AM
So explain to me why do we need to stay hidden on the web if we are free? Shouldn't it be the opposite?  
If it was really the case we wouldn't need to hide our ass. Nope, definitely we are not free, you can't say what you want on the web without getting censored, there are rules, there are ISP rules, platforms rules, hosting rules, email providers rule and so on. you can't use the internet without being monitored (doing legal or illegal)

People thinking the internet is decentralized are truly living in their own bubble

I don't agree completely,  but I don't disagree completely neither.

There are some limitations in the internet the way it is, but there is still space for a free web. There are many initiatives like firefox,  bitcoin, bitcointalk,  reddit, 4chan, BitTorrent,  and so many other interesting initiatives

If you want you can just buy a domain and do whatever you want with it.

The internet is more decentralized and more free than the rest of the world and our lives.
Just take a look at the news for example. People are saying whatever they want here in the internet,  but they can't on TV. However,  you have to say what you want in your own platform,  not on someone else's,  like Facebook.
