Oh rats, i overlooked something:
Tails is a security distro... Are you using Tor???

If so, read this thread: https://bitcointalk.org/index.php?topic=113116.0 and report back if it fixed your problem Smiley
4722  Bitcoin / Electrum / Re: Cant conect to any server, endless syncro. And now.... on: March 30, 2016, 09:20:04 AM
I have tried 10 random servers in past 2 days. I can access sites but getting some "unable to connects", even changing pages here. 1 in 10 aprox. My connection can be slow at times. but with the length of time, 2 days, trying to connect, should have found a window?
 Sory never pinged or telneted, can learn if needed.

It's pretty simple, most linux distros have telnet out-of-the-box.

I opened electrum, copy'd the IP and port from the first server in my server list, and did following commands on my debian server:
Code:
telnet 46.166.162.163 50002

The server's response was
Code:
Trying 46.166.162.163...
Connected to 46.166.162.163.
Escape character is '^]'.

If you can connect to the ip/port, your electrum client should be able to connect to... If not, the problem is laying in your OS's network setup, or in your home/office network setup.
I'd suggest trying to connect an electrum client from your normal desktop. Make sure it's on the same network as your tails installation. If the desktop can connect properly: it's your linux distro setup. If you desktop cannot connect normally, it's probably a firewall or router that is blocking your connection...

20100 Yovi is worth around 26BTC
So be confident I will pay  to get my Yovi back.
It's worth much more than I ask.

You seem very certain, i wish you good luck in finding a lender...
4724  Economy / Lending / Re: Looking for 0.9BTC loan. have collateral. on: March 30, 2016, 08:24:07 AM
Hi.
I need a loan of 0.9BTC for 21day (3weeks)
I will pay 12% interest.
My collateral : 20100 Yovi coins

20100 YOVI would have been acceptable collateral if there was enough being traded.
At the moment, the total of all BUY orders for YOVI is under 70 YOVI. So in case you defaulted, it would take the lender ages to sell all those coins in order to recuperate their loss. If he would fulfill all the current buy orders, he would make less than 0.1BTC back  Sad

Face it, i've bought some YOVI to, and i had to sell them at a big loss.

Hello. I’m a total novice in cryptocurrency world. I have an experience of mining bitcoins on my home computer however I understood that it was a waste of time and electricity.

Now I would like to try mine some coins at a cloud mining service. Can you tell me some reliable services? Because I read about a lot of fraud services so I’m a bit worried.

Thanks  Smiley

I'm not completely convinced there are good cloud mining websites available... There are a couple honest ones out there, but i'm not completely sure you'll ever make a profit investing in them...

Mining, as you say, is only for people with very cheap electricity rates and a huge budget... The only way to obtain bitcoins for normal people are either work for them (either use your skills, or join a signature campaign), or buy them directly.
4726  Bitcoin / Electrum / Re: Cant conect to any server, endless syncro. And now.... on: March 30, 2016, 08:08:37 AM
Thanks for answering.
I`m using tails, with electrum 254.
there is no tx id, because my signed tx cant be broadcast due to no connection (red circle) or endless syncronize of network.
 I think the file is yesterdays failed tx, but file is empty. (outside persistance)
If i could send the tx, it would be output from  : 13qqk4VnZR8G6VUNu3kqggU5BHe2uGUabe
 On network page it says: getting headers from 1 node.
electrum came with tails 211

I can basically think about 2 problems:
- your network settings have a problem (this can either be the network config of your tails distro, the use of tor or the setup of your home network, including firewalls and routers).
- you're connecting to a faulty node.

Since the second problem is easyer to fix, let's try this one first:
Have you tried changing your server? Double click on the red circle, disable "select server automatically", pick a random server from the list... If it doesn't work, pick a different one.
If you tried 3-4 servers, and none of them work, it's probably your network setup. Can you open websites? ping the electrum nodes? telnet to the electrum nodes on the ports shown in the network config of electrum?
4727  Bitcoin / Electrum / Re: Cant conect to any server, endless syncro. And now.... on: March 30, 2016, 05:24:02 AM
....on the send tx pg my tx is gone but there is a file by the QR code. when opened it adds this: #!/usr/bin/env xdg-open  to the pay to box. Please help.

 electrum 254, on tails   tried auto and non, plus many servers. Thanks.

I have some troubles understanding you... Is it correct:
- you're running electrum 2.5.4
- you tried to pay somebody, but cannot see the transaction in the history
- electrum created a file? when trying to pay somebody?


My questions:
- it seems you're running linux ((#!/usr/bin/env), which flavour, how did you install electrum?
- can we get the transaction id, or at least the address from which you tried to send coins?
4728  Economy / Service Discussion / Re: where did all the high paying signature campaingns gone! on: March 29, 2016, 06:31:13 AM
It's simple economics:

If a company invests x coins into a sigcampaign, and can make 2x coins from the ads in return, it's a good deal... But if they cannot make a profit with the traffic generated from the sig space, they just shut down their campaign.

Seems like the amount of profit generated with sig traffic went down, so a lot of them closed up shop...
4729  Bitcoin / Mining speculation / Re: Wanting to get into mining on: March 29, 2016, 06:24:42 AM
This assumes the difficulty doesnt change in 170 days?   Like it jumped 180% the last 170 days.

This is why i clearly put it in my assumptions... I know it will change, but not by how much, so for the sake of the calculation, i kept it at the current diff, but i clearly indicated this fact so the OP knew he had to think about this.

It also assumed a old price on S7's.  Take new price of 582 - 100 dollar coupon.  Your talking a brand new S7 for 482 or so plus shipping... so a decent decrease in price.

So this does change the price of gear a good amount.  You are right about difficulty though we don't know if it will be a smooth ride of next gen comes out and just adds ton of has... time will tell.

I didn't think about coupons, good point Smiley

^^^^^^^^^^^^^^^^^^^
You need to add shipping cost and POWER SUPPLIES cost. Diff will jump quite a bit now that Bitmain has lowered the S7 price and all the fools will jump in and buy them.

I did add shipping costs, but forgot about PSU's, thanks for adding this...

All in all, i think my calculation still paints a picture for the OP, it wasn't meanth as a guarantee of income, and i did add a lot of assumptions at the top, so the OP should know this is a guesstimate, and can change if any of the assumptions change

I have two invites that anyone can have. Shoot me a message.
Thats nice of you thanks mate.I'm sure the runner ups will appreciate it.

How does everyone get these invitations,  if you get a couple with new accounts then I would be happy to give away any that I receive on sign up.

Well... I guess it depends on your activity... I verified almost all my accounts, and immediately got 8 invites. My brother just added his BTC addres, and didn't get a single invite so far.
It's just a guess, but i think it has something to do with the activity.
4731  Bitcoin / Development & Technical Discussion / Re: How Many Bitcoin Transactions are <$100 on: March 25, 2016, 10:49:51 PM
Also, you have to realise a lot of those <100$ transactions will probably be coins being sent back to a change address of the original sender... So it'll be pretty hard to know how much money actually changed hands.
4732  Economy / Services / Re: [FREE] Keybase.io invitations : 2-3 spots on: March 25, 2016, 02:44:08 PM
The three winners are known, i'll PM them right away.
If the winners do not respond to the PM's by tuesday, the invite(s) will go to the runner up.

4734  Bitcoin / Bitcoin Discussion / Re: Suggest me Safest bitcoin wallet on: March 25, 2016, 02:09:38 PM
Thank you but in which step i transfer my existing bitcoins to paper wallet that i created?
Can i permanently store in usb stick instead of printing?I think that would be more safe as paper can sometimes be easily lost or damaged.


Steps:
1) create the paper wallet, print it (or keep it on your usbstick)
2) scan the QR code of the PUBLIC key with your mobile, mail it to yourself, DO NOT scan your private key
3) transfer your funds to the public key (address) of your paper wallet, double check your public key before sending your coins
4) safety

If you ever need the funds:
1) install a mobile wallet on your phone
2) sweep the private key
3) use your coins, transfer the leftover ammount to a safe wallet (preferably a new, unused, paper wallet)

You CAN store the USB stick instead of printing it, but be warned: even an USB stick has an expiration Wink. Personally, i have printed my paper wallets (BIP38 encrypted), laminated them, and gave a copy to my brother to keep in his house.
4735  Bitcoin / Bitcoin Discussion / Re: Suggest me Safest bitcoin wallet on: March 25, 2016, 01:52:33 PM
Please tell me any safe paper wallet generating service that actually does not have access to the private key that they put on the paper?
I've already told you. Bitaddress.org or their source code: https://github.com/pointbiz/bitaddress.org. It is impossible to transmit the private key over internet without internet so use it offline. However, they can still affect the entropy of the private keys so do review the source code and compile it yourself if possible.
How to compile it my salf? i am new to paper wallets so pleasr guide me sir

bitaddress.org's sourcecode is javascript, it runs from your browser.... Just go to the link ranochigo gave you, download the sourcecode (as a zip file), unzip it on a CLEAN OFFLINE computer, open bitaddress.org.html with your browser, follow the wizard, print your paper wallet as pdf on a usb stick, print the pdf on an offline printer that accepts pdf on usbsticks, erase the usb stick, restart the printer, restart (or even reinstall) the pc => safe Smiley

PS => for the really paranoid:
- BIP38 encryption is a must
- you can run a linux live cd for these steps
- removing the pdf from the usb stick isn't good enough, overwrite the device by random characters several times (TIP: dd if=/dev/urandom of=/dev/sdd1 in case your usb is on /dev/sdd1)
4736  Bitcoin / Bitcoin Discussion / Re: Suggest me Safest bitcoin wallet on: March 25, 2016, 01:02:46 PM
There is no evidence that they would delete the private key. Even if they do, someone could have kept a record of it.

Yes. Bitaddress.org code downloaded and ran on a off line linux computer would be the best option since no one would have access to the private key except you.
^^This is a great answer

The only thing i wanted to add: if you use bitaddress and generate a paper wallet offline, you can easily work the other way around, and import the private key from the paper wallet into blockchain if you ever feel the need to do so.
You do have to realise your private key is "compromised" as soon as you use it on any pc that is connected to the internet, so you should do your business, and transfer the rest of the coins back to a fresh paper wallet ASAP.

The process is pretty easy to finetune, since a couple of those offline paper wallet generators can generate a paper wallet for the testnet, so you can easily experment without risking your coins  Grin
4737  Bitcoin / Bitcoin Discussion / Re: Suggest me Safest bitcoin wallet on: March 25, 2016, 12:50:18 PM
I want an online wallet
Blockchain.info

something that is independent and provides backup
you can export your private key from blockchain.info if you want to

can't steal the bitcoins even of they shut there service and when they do shut there service i should be able to easily restore my wallet
I don't think 100% security will ever exist... An online wallet is way less secure than a hardware wallet, a paper wallet or a cold storage wallet. I don't think there are exceptions
4738  Alternate cryptocurrencies / Mining (Altcoins) / Re: Should i mine or not? if yes, what should i get. on: March 25, 2016, 07:55:43 AM
Im thinking about starting mining, since i have access to 3 apartments with free electricity.

But i dont have the biggest budget to get started with, so im still thinking about if its worth it.

I hope you guys can give me some opinions.






Thanks Smiley
Like a couple other guys already said: if you have a GPU, you might as well use it to mine some ALTcoins.
I presume it would be best to benchmark your setup for different hashing algo's, and plug the results in here:
http://www.coinwarz.com/cryptocurrency

Then mine the coin that gives you the highest return.

You can also opt to buy an sha256 (bitcoin, peercoin,...) or scrypt (litecoin, dogecoin,...) ASIC or a new/used GPU.
In case of an scrypt ASIC or a new GPU, you should look up the hashrates and plug them into the link i gave earlyer... Be carefull for block halvings, price changes and initial costs for buying/setting up the hardware.

If you buy a sha256 ASIC, be carefull, bitcoin blocks will halve in a couple of months, the price might fluctuate and the diff might rise.
You can find the hashrate of allmost every piece of hardware here:
https://en.bitcoin.it/wiki/Mining_hardware_comparison

And you can plug in the numbers here:
http://www.coinwarz.com/calculators/bitcoin-mining-calculator


As a final note: free electricity does only mean guaranteed profit in case you are only using free hardware. If you have to buy hardware, there is a chance you'll never ROI, even with free electricity.
Most cryptocurrency have block halvings, price fluctuations and diff fluctuations. When buying hardware, also include cumstom charges. Also think about the fact that a lot of ASIC manufacturers only give a couple months of guarantee on their hardware (lots of GPU producers give 1-2-3 years of guarantee)
4739  Economy / Services / Re: [FREE] Keybase.io invitations : 2-3 spots on: March 25, 2016, 06:44:29 AM
Accepted, added to the list... Be carefull tough: if you do no specify how you'll use the key, there is little chance you'll win this one Smiley

i would join on this .

thanks !

Can I get a free Keybase.io invitation?

I want to establish my online identity with it. It will also be useful for me to encrypt some sensitive messages (like personal contact details, address etc.) which might be needed during a trade. (for example buying some physical goods and stuffs like that)

I will be highly obliged if you consider me in the giveaway Smiley
4740  Bitcoin / Wallet software / Re: Electrom or MultiBit? on: March 24, 2016, 02:12:15 PM
up until now i've only been using online wallets like blockchain.info.
i was browsing the forum and stumbled on this;
as a precaution i decided to get a desktop wallet, post my address here and just be more responsible with my coins, in general.

i went straight to bitcoin.org and looked up osx desktop wallets there.
bitcoin core is out of question because of the 50+GB download!
the 2nd and the 3rd wallets there were MultiBit and Electrom.
did some digging on their websites.
other than the usual we're the best and the safest on the home page,
what i've found was lengthy technical documents.
i'm not being lazy just a bit too busy for my own good!

which one of these two do you recommend and why? what are they're distinguishing features? is there a big difference at all?
are there any other wallets i've missed? that might be better than these two? and why?

p.s. i'm only looking for osx wallets!

I'm a big electrum fan, i like the interface and the fact that i have to enter my password before signing a transaction.
I also like their coin and address controll, their plugins, the fact that i can have a downloadable version, the fact that i can have a mobile version,  the fact that i have several servers to chose from, the importing/exporting private keys, HW wallet support,... AND the fact that they're free (Multibit HD actually charges a very minimal developers fee).

On the other hand, Multibit HD is a fine piece of software to, i just like electrum better .
