I'm glad that you solved the problem, probably issue was about some corrupt file which is caused by upgrade from old version of Electrum.Since you try deleting blockchain_headers file before and that did not solve problem you should not do that.Just make clean install and your wallet will work without problems.

You can have one wallet on many devices,this is not problem-only be sure that they are on clean PC,and that you set strong password.

This is very popular way to deceive users and steal their user names&paswords,and it turned out to be a very inexpensive and effective way.In last months many people reported here on forum and on Reddit that after they download Electrum wallet( as upgrade ), or as a first time wallet - that their BTC is send in transaction in a matter of a few minutes.So many check what is going on,and we see that if you search for "Electrum" in google search, first results is paying add from Google which is always phising site with fake wallet.

I report more then 15 such sites related to Electrum,but new one pops every day - and newbies are perfect targets for such trap.

If you see something like that report here : Report Phishing Page

The answer is very simple,most of active traders lost their coins on Bitgrail and it will need some time to get things back to normal.I see that today price is 15% up and also volume is increased from 34,637,300 $(Feb 14) to 57,244,300 $(Feb 15).

If what had happened had not happened, price of Nano would probably be over 20$ today.I just hope all stolen Nano will be frozen and who ever hack them will not profit from that.

Is anybody try new Nano desktop wallet,any improvements on sync?I guess we can still help us to sync faster with chain download separately,but I did not see that files posted here in last few days?    

At the beginning of Electrum seed contained 12 words,then from 2.0 to 2.6.4 version it have 13 words,and from next version to today it have 12 words again.But you should not to worry because Electrum seed is compatible with all versions,so your 13 words seed should work in last version of Electrum.

You can also make a backup of all files in Electrum folder before you delete them,just in case you need them.If you have some other PC you can try to install Electrum and use your seed in that way.

But before that try option with blockchian_headers file.

I think you should try to solve your problem with clean install of Electrum,as I suggested in post above.It means uninstallation of Electrum program and deleting of all files in his folder.Then download latest version and restore from seed.

Regarding blockchain_headers file,I just check and have only 1 file,no tmp.,but you should delete both,it will not harm your wallet in any way.After that just start 3.0.6 version of Electrum and give it some time to sync.File is about 40 MB,so time for sync will depend of server you are connected and your internet speed.

Very interesting idea and will undoubtedly attract great interest of players,especially those who are familiar with BTC.Also this should be good promotion for cryptocurrency in general.

I see you posted BTC address and that address is holding 1 BTC,but it would be good to sign message to prove that you really own that address.I only hope that the challenge is not too heavy,but for 1 BTC prize in any case it is worth to spend some time and try to hunt the treasure

I know that most people just check coinmarketcap and that number which defines BTC Dominance,and it is much lower then before.But as Red-Apple say,new coins are created every day and they take some volume and marketcap,but 99% of them have no other application then to make some quick profit for team who are behind the project and those who invested in an early stage.

Only coin which is maybe a serious competitor to BTC is ETH,but with a three times smaller volume and some 75+ billion US dollars smaller marketcap(todays data) it is still far away to become king in the castle.

One thing which is most important is that BTC is only decentralized crypto currency,I think this is the greatest advantage that he have against all others coins.

Some mining companies are present in Iceland for years,but by the news coming from Iceland great interest has begun to appear some six months ago.Now there is no way to host all projects who showed interest for mining operation,the reason is simple, there is not enough energy.

Recent news say that the question of taxation began to appear these days,it is very strange that mining companies who operate in Iceland do not pay tax.So maybe this is the reason why even with slightly more expensive cost of electricity is profitable to mining there.

If that changes and Iceland introduces taxation on crypto mining will this affect on mining companies to stay or to look for more favorable locations?

It is possible that with deleting of this file your problem could be resolved,but it is not 100% that will succeed in your case.There is a possibility that another file is corrupted also,so only solution would be to uninstall Electrum and manually delete all files in Electrum folder on the path which we mentioned earlier.

As long as you have the correct seed for your wallet there is no danger that you will lose your coins,so check your seed by clicking on symbol right next to the green dot and enter your password(if it is protected)then when you are 100% sure it's completely correct you can try to do some of the above procedures.

Interesting how "easy" that 9000$ level is achieved in just a hour or less,and it is still holding above 9200$.Four days ago that level is reached,but it was very short-lived.This time the situation seems to be much better,and even if price went under this level it is likely to recover quickly.

What I've read in the analysis suggests that such a development of events could lead to testing 10 000$ level or even 11 500$,but it is not very likely that price can be hold in that range for long time.However the market seems to be recovering,maybe it is due bad situation on stock exchanges or less FUD in last days.

It is a known problem which some users have recently,but the problem was to be solved with version 3.0.6.You can try to select different servers when you click on green dot-uncheck automatic selection and try to pick any other server from the list then wait to see if your transaction is show correct balance.

If this not help there is a possibility that some file in Electrum folder is corrupted,so you should try to delete blockchain_headers file in Electrum folder.It is located on  C: \Users\YourUserName\AppData\Roaming\Electrum\wallets (or %APPDATA%\Electrum\wallets) but to see appdata you need to click on File - View - Folder Option - Show Hidden Files(in Windows)

If you delete that file(only that file) your wallet will need to sync again(download that file) so give it some time for that.

Last option is clean install of Electrum(uninstall/delete all files)and then restore from seed.If you do that be sure you have 100% correct seed.

Here is link from Twitter Leyland Accept Nano It is not some big online store,but if you pay with Nano and you live in USA you can get very good discount and free shipping.

It is nice to see good opinion from Headphones.com regarding Nano as payment option in their store,it only proves that as a means of payment Nano have good future.I hope we will see some good news from Ledger also,it would be nice to transfer Nano to hardware wallet.

Some news say that "hack" of Bitgrail is caused by bad code which allow some users to get double balance when two orders are placed.

You can use one and the same address forever if you want to do that.An address that was once generated in your wallet always remains valid.Ledger Nano S is HD(hierarchical deterministic wallet) and for every transaction send/receive it create new address.This is only for your privacy,so if someone wants to keep track of your transactions and know how much coins you have, this option will in some ways protect your privacy.

There is many fake sites who pretend to be real and legitimate Electrum site,so be careful and download only from https://electrum.org/#home . When you search for "Electrum" you may see paying add at the top of the search results,it is fake and it should be avoided at all costs.

Before upgrade be sure to have your seed safe, and that it is 100% accurate,only in case something goes wrong.

It is true that people can not be prevented from doing something completely,but that influence that was previously present does not exist anymore.I know that some % of Chinese still finds ways to buy / sell cryptocurrency,but they are a minority that almost does not affect the price.I would say that we should not underestimate the strength and methods of the Communist Party in China.

I hope you are kidding about Dogecoin,year of the dog has nothing to do with price of Dogecoin.I like that coin from the start,but with unlimited supply it is difficult to expect some higher price in future.

Fatanut, there is a change in CoinPayments regarding rates for all members.It will stay like this as long as the price of BTC is below 13 500$.

Also this campaign requires merit points for any new participant,this is something what you could add to your table.Probably other campaings managers will also decide on this move in future.

I am glad that you nevertheless became a little optimistic regarding BTC,so your prediction is drop in price by 50%+ in next 7 days?Does this have anything to do with prophecies of Vangelia Pandeva Dimitrova maybe or is it only the idea of your brilliant mind?

I'm most interested in when your prediction is going to happen and 1BTC will be worth only 55$?

There from where I am BTC is still relatively unknown,especially for the tax office.So if I want to pay the tax on any cryptocurrency profits it become nightmare and the mountain of paperwork.But depending on the status employed / unemployed,and knowing the holes in the law I can pay from 20% and up to 60%.I consider everything above 30% as legal robbery,so best way for me when selling is to do that with someone directly and get cash on my hand.

But I hold most of my coins for future,when times come I will try to find way to pay as much as possible less taxes.If that means I need to move in some other country it will not be a problem.I am sure I will stay away from Japan

I was hoping that things would be done to your benefit in the end,but maybe you do not need to give up on this.You should try to contact their support on a regular basis,and also post on every forum,reddit,twitter,facebook and wherever you remember.I see you have some contact in Russia,so why not report this case to their authorities?Chance that it will do something are very small,but I would personally try to exhaust all the possibilities to find out the truth.

This means that if you want to receive BTC to SegWit bech32 address you may have problem because some sites/wallets simply do not recognize that type of address.We hope that this will change with time,and in the meantime you can use segwit-in-p2sh address format in Electrum if you follow these instruction : Create SegWit BIP49 Wallet
