I am currently on 38 weeks behind. I only have 512 dram, very slow pc and it is taking everything for this synchonization. Also cannot leave pc 24/7 runned anymore. Torrents and other potentially suspicious website are NOT an option so Could anyone please upload remaining blocks files on some fast server such as rapidshare.com?

Are those files that arrive to computer's hard drive from sync procedure 100% identical for every single worldwide bitcoin user who uses desktop application -qt with no matter on its version? Or do those sync files have microscopically small differences, e.g. the ones from X user on Y computer comparing to the ones from A user on Z computer?
Im asking this because I got the following idea. If they are 100% identical, so exactly the same files from sync arriving on hard drive, then they should be available somewhere else online too where downloading speed is much higher, e.g. rapidshare website. I could download from there into appropriate folder. I have seem some topic about this here:

http://bitcoin.stackexchange.com/questions/20493/faster-way-to-sync-my-new-bitcoin-wallet

But obviously i would expect trustworthy, safe and offical location where could be downloaded from. Im Not going to download those from torrents website.. It could be virus/warm/malware, it could be stealer, it could be keylogger of any kind (related or not to bitcoin), it could even be some legitimate safe file but for different purpose, etc.

I was referring to bitcoin-qt desktop software (.exe). I don't know what does ''Core'' mean and don't want to know. Also im not familiar with term ''private keys'' - never heard what this is. I only know ewallet.dat. But if private key is bitcoin wallet (ewallet) id then all cool.


ewallet = bitcoin-qt.exe (desktop application). Its the same. I have -qt. The term ''ewallet'' can be defined as web application or as desktop application.


I downloaded it but don't remember exact url link. It looks similar to this:

except nothing under Recent Transaction. Zero balance, even if i withdrawed almost two days ago. It should come in minutes, nothing came but thats because of sync.


On the link i provided in previous post says ''chargeback''. You can see it there.

Also i posted the new question here:

https://bitcointalk.org/index.php?topic=539818.new#new

but noone replied 

After running sync for over 47 hours, still no signs that it would ever come to an end. However the good thing is that in Task Manager near bitcoin-qt which is being runned does *NOT* say it isn't responding (=frozen) so there must be something what is being done. However I have deleted many files, even important one, for sync procedure. I have nothing left to delete on purpose to free up the space for sync.

Hi,

Could anyone please list me and and all disadvantages of Electrum in comparison with bitcoin-qt from any and all aspects such as:

- not being able to withdraw from particular websites if using electrum desktop application
- sometimes or always not being able to send or receive funds if coming (or going to) bitcoin-qt because of using Electrum
- high probability that Electrum in the future won't be able to be used (e.g. permanent server shut down)
- limited free usage (free trail)
- limited incoming and/or outgoing transactions per X time interval (day, month,...)
- limited amount of balance being able to be hold
- limited amount of incoming transaction
- limited amount of outgoing transaction
- not being able to send funds from Electrum to X location
- Electrum fees
- etc

So since I have giant trouble with bitcoin-qt im looking to switch to Electrum but would appreciate if anyone could please list me all Electrum's disadvantages.

Are you saying if using Electrum desktop software, which I expect to be available/online (for usage, not only to download) all the time 24/7, I wouldn't need to synchronize the blocks all the time? How it would capture the transactions then? You said I could try to switch from bitcoin-qt to Electrum (i chose it from your 3 suggestions). Now, since funds have been sent to ewallet (still not received), it is probably too late to try Electrum. I doubt I would have same ewallet id and due to obvious reasons I cannot define one.  So since funds have been already sent by me to my ewallet id, those funds would never arrive to Electrum because of different ewallet id and could be some other reason too. Im aware you told me I can export/import but im not so sure importing to Electrum ewallet.dat would enable me owning exactly the same ewallet ID. Im afraid doing this could lose my btc amount that hasn't arrived yet but the good thing is that I believe even if trying exporting/importing, IF something goes wrong, I could basically just resume with synchronization in bitcoin-qt.

It has passed almost 40 hours since I started synchronization procedure and so far very tiny progress. Im sure electricity utility bill will cost me more than the actual amount of btc arrived. The updating of blocks isn't going anywhere, almost frozen.

In bitcoin-qt isn't even exporting option but ewallet.dat can be easily accessed via Documents and Settings\User\Application data

However on the following link:

https://electrum.org/

I don't see Import option anywhere. How come? Plus according to their website i just provided, transactions aren't irreversibile (no refunds/chargebacks) anymore. See image on that website.

Also are there any other disadvantages in electrum?

Thank you for reply. On blockchain website I see the transaction in correct amount but it hasn't arrived to my ewallet yet so the reason is for sure incomplete synchronizing. However the following three questions still occur:

1. Is there a way i could synchonize for only my transaction or at least transactions that happened close to my, including my? I really don't see any reason why would I want to have saved entire history of everyone's btc usage.

2. Im planning to buy new computer soon and I would have to go through this procedure once again but is there any way to avoid it along known one - copy blocks files (from Application Data folder) from old to new computer?

3. Once synchonizing is complete, can I permanently delete any of those blocks files from first time synchronizing? Obviously up to date software data should remain after removal also but it might get outdated if I remove those block files. The reason for removing is mainly hard drive size - it really takes a lot of GBs. If the answer is ''yes'' then: how do I figure out which files can I delete so I wouldn't delete the one which contains also my transaction otherwise balance would go back to ''unknown'' (zero) one.

Greetings all,

Recently I was supposted to get my first EVER incoming (receiving) transaction into bitcoin. The transaction was supposted to be done in minimum few minutes and maximum approximately 1 hour. Now it has passed almost entire day and no funds have ever arrived. Balance still zero. I did some google research to find solution on my own and I think I found it but it doesn't solve the problem. Solution says that I need to first synchronize the blocks. I have no idea what are ''blocks'' and honestly I am so worried about my funds that I don't even want to know definition of ''blocks''. However the problem is that synchonizing needs GIANT amount of hard drive space and im running low with hard drive size (please avoid suggesting me to buy new one). Second problem is that this procedure has been processing for the past 10 hours and still not finished. It doesn't look like it will be finished any time soon. Due to this it seems like I will need to pay electricity bill more than the actual amount of incoming funds/btc is. Im very worried I lost my money because it wasn't synchronized. Question: Would it be possible and if yes how, that I synchronize only my transaction (transfer towards me) so the balance would be updated as fast as possible? Its really taking very long. I see no reason why would I need to download entire list of transactions from millions of bitcoin users around the world. I just want my so balance could be updated. How could I do this? Procedure of sync is a way too long.. No much progress at all and I don't know where my money is.. It should be in btc ewallet long time ago...Please what to do??
