So, this is essentially a brainwallet right? Huh

That's pretty much all you need to know about this to know how stupid it would be to use one. It's so so easy to think that you've remembered a phrase and then you forget it one day.

Bitcoin was supposed to be used as a currency, not only a form of investment. However, it's been more successful as a form of investment, a "speculative asset".

Do you guys think that this can change in the long term ?




I think bitcoin not failed as a currency because it is good and trusted. Actually bitcoin now is so popular and famous because you can see it all over the world you can see it in the news, advertisement or even in the movie because there is so many people that is rich now because of bitcoin.
I'm not going to say it's failing, because it's just a one-sided assessment of some users, although many people say that fluctuations
can not be used for currency, it's free they say like that, but in fact I can still easily spend bitcoin on some sites easily..

I wish there was less fluctuation in the price so that people could focus more on developing technical advancements. It's hard to focus on that kind of stuff when there's drastic changes in the price.

I would increase the contrast on the items in your navbar. They're pretty hard to distinguish against the background, especially those buttons on the very top right corner.
64  Bitcoin / Development & Technical Discussion / Re: Idea for anonymous reputation on sites like Paxful on: June 26, 2018, 03:03:31 AM
Wouldn't that limit most people without large amounts of reputation to only a single open trade? I suppose that may be beneficial. Just trying to think of blocks in the user experience.
65  Bitcoin / Development & Technical Discussion / Re: Looking for an linux (or windows) offline SHA-256 binary calculator on: June 18, 2018, 02:08:15 AM
If you're using Windows and you'd rather not have to install any additional software, there's a certutil command available to calculate hashes (among other things).

To calculate a hash, do  certutil -hashfile filename algorithm

For example, certutil -hashfile image.png SHA256

The available hash algorithms are MD2, MD4, MD5, SHA1, SHA256, SHA384, and SHA512.
66  Bitcoin / Project Development / Re: Stephen Pair CEO BitPay - How Blockchain is disrupting database technology on: June 18, 2018, 02:01:08 AM
Come to BlockchainConf.Tech in Atlanta USA in September for a unique discussion on how blockchain will make traditional databases obsolete. Also speaking will be Chris Ferris, BM CTO Open Technology, Chair of the Hyperledger Technical Steering Committee, Marley Gray Principal Architect - Azure Blockchain Engineering, Board of Directors - Enterprise Ethereum Alliance; and many, many more blockchain superstars. Full details can be found at BlockchainConf.Tech

Blockchain will never, ever, ever made traditional databases obsolete. Blockchains cannot even come close to rivaling the speed and footprint of a standard database, SQL or No-SQL based. That's never been the point of a blockchain. What if I want to store a database of sensitive information? Why would I send it out all over the world? And yes, you could encrypt it but that's just additional overhead then.[1] Blockchains are for having a decentralized, immutable, auditable database. Many people don't need that and don't want that. Say you have a traditional DB and someone changes their email address. All you have to do is change that value. But with a blockchain, you'd have to create another entry, taking up more space.

Blockchains solve a very niche solution, one that happened to greatly benefit Bitcoin but is not nearly as applicable in every situation as people like you make it out to be.


[1]: Actual sensitive data in a database should always be encrypted at rest. That's a big part of stopping would-be hackers from taking everything.

68  Bitcoin / Development & Technical Discussion / Re: Earning LN routing fees on: June 17, 2018, 04:32:43 PM
Definitely.
The LN is still being tested currently. Once it is fully released and people start using it, there will be routing fees.
Currently it is more like testing how payments in the future will look like  Cool
I'll be patient and wait for the Lightning Network to leave beta phase. I think it has some way to go before becoming a user-friendly second-layer solution.

I think it's going to take a lot more time to see people making money off of routing fees than it's going to take to see it being used by people. The usability is more than half there now. But it's still difficult to make money running a node.

Actually this is probably the first actual question I've seen with interest in making fees from LN, since most users anyway (far as I could tell) were really just interested in using LN. The appeal of low/no fees and instant transacting aside, it's for me also personally useful to open channels with people I frequently transact with, almost as an additional layer of "trust" or familiarity. Definitely don't see how the potential for earning fees would encourage adoption, but I suppose I'm not thinking of business scale.

I've seen plenty of people wanting to know how they can make money by routing payments. But a lot of them seem to not understand the scale required of both the whole network and the number of channels their node will have to maintain in order to make any amount of money they can recognize

70  Bitcoin / Project Development / Re: BandZ - The future of VPN and Bandwidth blockchain on: June 17, 2018, 04:09:27 AM
So...I am to believe that the well experienced team behind BandZ are incapable of putting together a functioning website, something that anybody with $5 and an internet browser can do on a number of sites? But they're still somehow capable of running an ICO and taking people's money and promising to make...a VPN? Why try to solve a problem that nobody has? We already have VPNs. Free VPNs, paid VPNs, self-hosted VPNs, and then there's Tor and company if you're looking for something decentralized. I don't see the point of this at all.
71  Bitcoin / Development & Technical Discussion / Re: If wallet.dat shared or stolen, then encrypt it? on: June 17, 2018, 04:01:24 AM
If A and B are using the same wallet file, it doesn't matter if either of them encrypts it or when. They're already sharing the same master seed which is used to derive all of their addresses. Encryption only protects against people getting access to your computer and attempting to get to your private keys (master seed) but in this scenario you've let A and B share the same seed. They would both be able to spend the other's money.
72  Bitcoin / Hardware wallets / Re: Hardware wallet 2.0 - Making them for the smartphones as a mobile case. on: June 17, 2018, 03:54:45 AM
Am I just missing the point here? I use hardware wallets for long-term storage of large amounts of crypto - the last thing I want is to be carrying them around with me and expose them to the risk of theft or loss. For transactions on the go, I can just store a small amount of crypto in a mobile wallet.

Agreed. This totally destroys the purpose of hardware wallets, increased security. Carrying it around on your person all the time would be a horrible idea. Anybody seen with one (and you would be seen because it'd be on your phone) would be a prime target for robbery. The fact of the matter is if you're being held at gunpoint, it doesn't matter how secure the wallet you're holding is.
73  Bitcoin / Development & Technical Discussion / Re: How does the wallets know which addresses to recover in Hardware Wallet recovery on: June 16, 2018, 01:17:44 AM
I believe they generate up to a certain amount by default, that can be configured to be larger if it's not generating all the addresses that you've used.
74  Bitcoin / Hardware wallets / Re: New Ledger native desktop app to be released on July 9th, 2018 on: June 12, 2018, 02:25:37 AM
But they're not stealing your xpub from the app, nothing like that.

Thatīs not even possible, as this data never leaves your ledger nano. And google would never do that.

What they do is what they say in their privacy police, which is something like "everything you do here we will sell to third party"
The xpub is the extended public key from which all of the addresses in the wallet are generated. It leaves the device so that the wallet can display your addresses and retrieve balances. It does not give control of your coins to anybody that has it, but it does reveal all current and future addresses.
75  Bitcoin / Hardware wallets / Re: New Ledger native desktop app to be released on July 9th, 2018 on: June 12, 2018, 12:15:19 AM
I found it a bit boring to have to go through Chrome and install/use an application..

Thats the same thing which makes me feel quite uncomfortable when accessing my nano s.
It just doesn't feel right to install google chrome and use a chrome application to access your cryptos, especially on linux  Roll Eyes

I am definitely looking forward to use ther native application. For BTC we can use electrum to bypass the usage of chrome.
But there aren't proper wallets available for other coins (e.g. ETH). And im not a big fan of MEW :7


Lets see how long it takes until the application is released and how long the 'future releases' with additional features will take.

The thing is, because of the security model of the ledger devices, you don't have to worry about the platform you use it on, as long as you actually use the device to verify everything.

Chrome app disadvantage  is not about security, but privacy.
Google chrome is stealing your personal data and selling to companies. If you use ledger nano app on crhome, you are probably going to see ads related to crypto.

Itīs may even be considered a security risk, as now someone else knows you own crypto...

As much as I hate Chrome, I don't really think it's as much of a privacy risk as some people might make it out to be. Sure, when you install the app, Google knows that you searched for and installed the ledger chrome app. But they're not stealing your xpub from the app, nothing like that.

That said, I am happy to not have to rely on Chrome because with that said, I don't want Google having a big list of ledger owners.

AM has been stable for a while now. While I'm not actively developing it anymore, if anybody has any feature requests, I'll gladly take a look at them.

I don't know do you like my ideas or not but still, I would like to suggest something.

!mintip it should say minimum tip amount for all currencies.
!minwd it should say minimum wd amounts for all currencies.
!wdfee it should get the dynamic fee data for all currencies and print them.

right now !last prints about the btc blockchain last block.
is it possible to add something like..

!last ltc - prints about ltc last block.
!mempool ltc - prints about ltc mempool size.


Thanks.


The first three wouldn't be something to add to AM because they're things that are easy to find just on the site.

The last couple won't be added because I don't run a LTC node on my machine and don't have any plans to.

The last ones are fine ideas though, just not something I'm going to add.

79  Bitcoin / Electrum / Re: manually adding transactions on electrum on: June 07, 2018, 02:17:48 AM
how do I do off-line signing of transactions then?
Preferably you would use a computer/laptop that's never been online, something like a fresh linux install.

For instructions on how to do this using Electrum, click here.

Other wallets have similar instruction manuals you can find just by using Google.
80  Bitcoin / Project Development / Re: I created crypto.eu - A nice well-looking website but useless on: June 07, 2018, 02:14:52 AM
I suggest allowing the user to scroll through the list no matter where their mouse is on the screen. Having the tip helps but I didn't even see it until I figured out that my mouse had to be over the center left panel. It's the only thing on the screen, there's no reason to restrict where you can scroll through the list. It looks very nice though.
