261  Alternate cryptocurrencies / Altcoin Discussion / Parity+Ledger Nano S on: September 17, 2017, 03:59:24 PM
I have a Parity ETH wallet , and i want to buy a Ledger Nano as well.

I will want to add a second ETH account to my Parity wallet, and this second address will be the one provided by the Ledger Nano.

But where is the "Import address from external device" menu option ?

The stock market is 70% overvalued ... crash now inevitable





Author Charles Dickens' classic, A Tale of Two Cities, begins this way: "It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness ... ."

According to one stock market analytical firm, GMO, today's market behavior resembles Dickens' book, which was published in 1859 and was set during the time of the French Revolution some seven decades earlier.

As the firm noted, in recent days much of the investing and financial world was focused on a meeting in Jackson Hole, Wyoming, attended by Federal Reserve chairperson Janet Yellen. But GMO analysts were watching other things and events happening in the market.

In August, the firm noted in its monthly report – reproduced in part by Zero Hedge – that Shiller P/E, a respected metric for measuring U.S. equities valuation, surpassed 27. Given that normally its range is somewhere slightly above 16, it appears that valuations are looking a bit larger than they should be.

What's more, GMO noted, the last time the Shiller P/E was above 27 was in October 2007, "and we all know how that movie ended," the GMO report said.
 

'A tale of mediocrity, at best'

And though no one at the analytical firm is saying that the nation and the world are set to experience another Great Recession and near-meltdown of the global economic order – and nothing is written in stone saying that stocks are not allowed to become more expensive – "we continue to maintain our bias against U.S. stocks," the firm said in its report.

At the same time, the firm said, it was tracking a widening disconnect between fundamentals of the U.S. economy, corporate America and their stocks. "It really is a tale of two cities," the analytics firms said, "one of mediocre fundamentals versus a meteoric rise in markets."

In assembling some relevant metrics pertaining to the overall health of the economy and some top-line/bottom-line figures from the S&P 500 index, the firm looked at gross domestic product growth, productivity and household income, in addition to some others like revenue and earnings for U.S. stocks, just to round out the assessment.

"It is a tale of mediocrity, at best," the firm wrote in its report.

After that, analysts contrasted those metrics with actual market returns of the S&P 500 Index spanning the past five years. "Truly meteoric," the firm wrote, adding this caveat: "As an aside, we at GMO have always been leery of drawing too many investment conclusions from staring at economic data–we are more valuation-oriented, after all–but even we are struck by the divergence."

Cool

So who was investing in stock market is moving to crypto because of this?

But hey.. who guarantees that crypto markets are not overvalued as well and will crash like stock market, just a little later??

According to this paper china will try to block bitcoin exchanges and p2p network from the great firewall.

I like to see what will be the future of mining in the country if this happen and especially how this chinses mining cartel will survive. Is surprise that Jihan and Bitmain spent a huge stake of money to fight over silly things like Block size, blockstream evil etc and has not predict that something like that wil be possible to happen.
I will laugh for months if Jihan ask the help of blocstream to keep operating in china

Wasn't everything supposed to be decentralized and not attackable by a simple stupid IP ban like this??

Now we will have the proof it is actually centralized.
If a simple IP ban defeats the entire network, ... i've no words left to say

How should they track the IP and then the coins? We just could use VPN and that would it be, wouldn't it?

If they know the IP and if it belongs to a VPN , they can ask the VPN provider who used that IP that day, and they find you.

So you better use TOR instead of a VPN.
Maybe using TOR alone is better than VPN together with TOR (See also the first response and comments to this question: https://tor.stackexchange.com/questions/1945/tor-via-vpn-good-extra-level-of-security-or-unnecessary )

About the path of the coins, it's simple:
BTC address A (your address) => deposit to B (your BTC account on betting site) => withdraw to address C
Imagine the betting site logs these movements, so they know there's this path from address A to C. They can tell the authorities

About how they find out which IP sent coins from BTC address A... well, i think there's plenty of information about BTC being "pseudoanonymous" and not anonymous.

Example:
Quote
How is anonymity defeated?

There are basically three ways to de-anonymize Bitcoin users.

First of all, even though Bitcoin transactions are randomly transmitted over the peer-to-peer network, this system is not airtight. If an attacker, for instance, has the means to connect multiple nodes to the Bitcoin network, the combined data collected from these different nodes might be enough to determine where a transaction originated.

265  Bitcoin / Development & Technical Discussion / Re: Wallet mixer possible? on: September 13, 2017, 06:00:28 PM
Until such wallet exists and if you don't want to pay fees in a mixer service you can use a gambling website to send your deposit there. Play a single bet with minimal value like 1 mBitcoin and wait a few hours, withdraw to another address from the one you send your deposit. Keep creating as many wallets as you like and you can use this simple yet effective way of mixing your coins and getting fresh coins, fresh for you only.

Many gambling websites would not tolerate this behavior for long. They want you to actually gamble there
and lose your funds in the process and not become a partner in crime for crypto laundering.

Some operators even explicitly prohibit this kind of behavior in their terms of service.

That is not a problem.
You can bet all your coins on bets with high probability (and lowest odds), so they cannot say you are not betting all your money.
Then after you win you withdraw everything.
It's not against their TOS, you actually are betting every single coin you have deposited and they can't find out you did it just for other reasons.

But the problem with this approach is the same as VPNs, they log everything so all your money movements are not untraceable as they claim.
When you withdraw , authorities know you are the same person who deposited/bet those coins.

And Monero/ZCash/ZCoin claim to be untraceable but often new researches come out that find privacy vulnerabilities in those currencies, so i would think twice before using Monero if i were doing shady stuff, it would be too risky not having the guarantee it's untraceable .

Many voices here on this forum say that the only solution is still a wallet over TOR (whatever crypto you want, even Bitcoin)
266  Alternate cryptocurrencies / Speculation (Altcoins) / Re: Dump? on: September 12, 2017, 09:46:19 PM
What is the reason of this drop? Any news i missed?

China bans ICOs and cryptocurrency to fiat exchange in the country for now that is the reason behind the drop. You may dump as well If you like to because there are too much uncertainty in the market. Cool

If crypto really is a treat to bank tyranny, i am surprised it is taking that long for them to ban the BTC exchanges.
So the BTC ban actually is a good sign, it means crypto can really replace bank accounts and they don't like it.

We should expect such a ban and similar failures of crypto-related centralized services, because centralized services are easily attackable.

They have invented a decentralized money just to avoid such problems, and we are still using centralized services??

We should change mentality, we should start preferring more untraceable ways of doing things at the expense of some user friendliness.
Often the easiest way is not the safest.

For example buying with credit card it's easy but the drawback is...  they know what you bought and how much you transacted.

What if the betting site logs every movement? A trace would be left.

And also you have to be careful to split the withdrawal to multiple wallets or one can guess the path by observing the same amount being transfered  for the deposit on the betting site and the withdrawal.

At the end of the day you can forget about these tricks by connecting the wallet via TOR for peace of mind
268  Bitcoin / Hardware wallets / Re: Ledger Nano: is it secure? on: September 09, 2017, 11:33:41 PM
Very good.

And if someone steals your Nano they cannot read the Seed because they haven't the PIN.
But they may disassemble the Nano and directly read the flash memory in it, and copy directly your private key.

So you better not lose your Nano and if so, immediately restore the wallet with the seed with another Electrum instance and transfer the coins elsewhere
269  Bitcoin / Hardware wallets / Re: Ledger Nano: is it secure? on: September 09, 2017, 07:26:32 PM
What happens if my Nano burns or i lose it?

Does it support BIP 38 seeds so that i can restore my private key ?
270  Bitcoin / Hardware wallets / Re: Ledger Nano: is it secure? on: September 09, 2017, 01:39:54 PM

Anyone of you that has a Nano and can confirm that it displays transaction info upon PIN request ?
And to answer the OPs question... yes, it displays the address and amount and you have to confirm it before the transaction is signed and returned to the software wallet for broadcasting.

Sounds good then Smiley
271  Bitcoin / Hardware wallets / Ledger Nano: is it secure? on: September 09, 2017, 01:05:58 AM

Suppose i am using Electrum with Ledger Nano S.
When i send a payment, i must manually enter the PIN on the USB device (source: https://ledger.groovehq.com/knowledge_base/topics/how-to-setup-electrum-nano-slash-nano-s )

But i wonder if the Nano shows me the transaction details as well ( destination address(es), amount(s) ).
If not, i don't consider this solution very safe.

Suppose a virus on my PC acts as a man-in-the-middle when the payment command is sent from Electrum to the USB device.
The virus may change the payment destination address on-the-fly after the command goes out of Electrum wallet but before it enters the USB bus to reach the device.

Anyone of you that has a Nano and can confirm that it displays transaction info upon PIN request ?
272  Alternate cryptocurrencies / Altcoin Discussion / Re: Ethereum password on: September 04, 2017, 10:41:41 PM
This password in only for encrypt your wallet. To access the wallet in any other PC, you need the private key

So i better backup a few copies of the "keystore" folder in cold storage

You need your private key anyway, this is only for higher level of security. The password is just to make sure the person is the owner of the wallet, you can't Access your wallet with only that password, I mean.

Yes i got it.
The password is for encrypting the private key, which resides in the "keystore" subfolder inside the data folder , right?

So after i encrypt the wallet with my password, i also may want to backup the keystore subfolder to USB stick and/or cloud drive , so that if my PC burns one day i can get my backupped "keystore" folder which has the private key, and i decrypt it with my password

274  Alternate cryptocurrencies / Altcoin Discussion / Ethereum password on: September 04, 2017, 09:47:33 PM

I have installed the offical Ethereum Wallet from ethereum.org, it asks for creating a password to protect my account.

Is that like a BIP38 Seed that i can use to restore my wallet from another PC if my hard disk burns?

Or is it just a password to encrypt the wallet files i have on my PC, and i must backup my wallet to cold storage manually ?
275  Alternate cryptocurrencies / Altcoin Discussion / Bitcoin Cash wallet with JSON-RPC on: September 03, 2017, 10:57:46 AM
I want to get a BCC wallet which provides JSON-RPC API just like Bitcoin/Litecoin Core do.

Which is a suitable wallet for this?
Bitcoinclassic or BitcoinABC support it?
276  Economy / Exchanges / Re: BTC-e hacked ?? on: September 03, 2017, 10:45:56 AM
From here https://btc-e.nz/refund i read that you can get the 55% of your money immediately without verification, BUT you have to refuse to take the 45%.

It would not be that bad , but what should we do for getting also the 45% ?
I did not find an explanation for this on the official site.

I have "just" 1.43 ETH in total after all, but it's just for curiosity
277  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Sia - Decentralized Storage on: August 28, 2017, 09:14:01 PM
We may want to estimate the profit of renting storage vs electricity cost.

Say that you have a PC with Celeron CPU and 2x 6TB internal hard drives and you leave it running 24/7 just for SIA.
How much is it going to consume ?

Assuming that you rent all your 6 TB at 12-15 $ / month ($2/TB/month) , i am not sure you can cover the energy costs, because it depends on the disk reads/writes operations done in that month, as the disk too consumes power based on I/O activity.
278  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Sia - Decentralized Storage on: August 25, 2017, 04:03:48 PM
I have try to install sia wallet on a offline computer.

I have copy the consesnsus.db from an online and fully synced pc, but when I try to load a wallet from my seed it says:

error when callling /wallet/init/seed: cannot init from seed until blockcjain is synced

I hae also try to do it on the terminal using --force but it says wallet has not been encrypted

These are the technical problems that can kill a project like this.
Now i understand why it is dying.

We need someone to contribute to the source code to make it better.

Maybe your issue is that the wallet needs to be synced with the blockchain but your PC is offline.
Retry after enabling the network
279  Alternate cryptocurrencies / Announcements (Altcoins) / Re: [ANN] Sia - Decentralized Storage on: August 24, 2017, 08:46:22 PM
Can you tell me about reliability/redundancy?

What happens if the node that has my files goes offline forever? Will i lose my files or are there other copies of them in the network ?

I don't pretend that SIA duplicates my uploaded file to every node of the network, that would be unsustainable, but at least i want to know how many
 redundant copies are there.

That is important because , unlikely Onedrive/Gdrive etc.,  a P2P network like SIA has poor uptime for each node, i.e. each node is not always online and there's no guarantee that it will keep working with SIA forever , while Onedrive servers have 99.9% uptime and will be there forever.
So i think that some redundancy is needed for a P2P cloud storage, i just want to know if SIA has it.

I would pay more than 2$/month but i want to be sure that i won't lose my files.

What happens if a host goes offline? Absolutely nothing for you in terms of file availability. Each file is uploaded to 30 different hosts by dividing it in chunks and sending each chunk to 3 different hosts (a redundancy of 3x). The algorithm that distributes the chunks is called Reed-Solomon, and ensures that 20 of those 30 hosts can go offline and you still will have access to your files.

But moreover, in Sia hosts are heavily de-incentivized to go offline. Each host is risking collateral when you make a contract with them (several times bigger than your payment), and if they don't keep an uptime of 97%, that collateral will be lost.

So you see, hosts in Sia keep each one of them an uptime of 97% (at least) and you only need 10 out of 30 to recover your files. That is an availability of your files bigger than 99.9%

This sounds so awesome.

I don't understand why the price is dropping and people are giving negative feedback at this point..
