Electrum

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?

Correct.

How it would capture the transactions then?

The last I heard, Electrum uses a client/server model. The server stores the complete blockchain for you. Your Electrum client communicates with the server.

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),

ewallet? I'm not familliar with ewallet. I had assumed you were running Bitcoin Core. I assume that ewallet (whatever that is) provides you with the ability to export your private keys?

Quote from: dolphin001 on March 27, 2014, 04:08:29 PM

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.

If ewallet allows you to export your private keys, then you can import that private key into Electrum. However, you'll lose the Electrum advantage of rebuilding your entire wallet from a seed if you do that.

Instead, what I would do is temporarily create a wallet at blockchain.info, and import the private key there. Then install Electrum on your computer. Then use blockchain.info to send the bitcoin funds to one of the bitcoins addresses from your Electrum wallet. Then simply abandon the blockchain.info wallet.

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.

See my notes above.

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.

I am sure. As long as you export and import the correct private key, you will have access to the funds at the same bitcoin address.

Im afraid doing this could lose my btc amount that hasn't arrived yet

As long as you are careful and keep a good copy of your current wallet file from your current wallet, you should be fine. If you damage or lose the current wallet file, then you'll have a problem.

Quote from: dolphin001 on March 27, 2014, 04:08:29 PM

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.

First you say ewallet, now you say bitcoin-qt. Perhaps we should start by figuring out what wallet you are using right now and where you got it from? If you are using Bitcoin-Qt or Bitcoin Core, then you can definitely get your private key and import it into another wallet. Doing so will give you immediate access to the bitcoins that were sent to the address.

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.

Bitcoin really isn't very good for sending extremely small value.

If we assume that your current computer uses about 60 watts of electricity, and it has been running for 40 hours, then you've used about 2.4 kWh of power. If your electric provider charges you about $0.11 per kWh, then You've probably used about $0.26 worth of electricity. If you have done nothing else with your computer during this time, then you can perhaps attribute the entire $0.26 to bitcoin usage. If you have done anything else with your computer (such as participating in discussion here at bitcointalk.org), then you'll have to figure out what percentage of the power went specifically to bitcoin blockchain synchronization, and what percentage would have been used by you anyhow even if you weren't synchronizing the blockchain.

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

Bitcoin-Qt should have a file called "wallet.dat", it should not have "ewallet.dat". Where did you get your Bitcoin-Qt? Are you sure you got it from somewhere reliable?

To access the private key in Bitcoin-Qt, you use the "Console", found in the "Debug Window" under the "Help" menu.

Enter:

Code:

dumpprivkey 1yourBitcoinAddressGoesHere

Replacing 1yourBitcoinAddressGoesHere with your actual bitcoin address.

However on the following link:

https://electrum.org/

I don't see Import option anywhere.

How come?

Because the Electrum website is not very helpful.

Quote from: dolphin001 on March 27, 2014, 04:08:29 PM

Plus according to their website i just provided, transactions aren't irreversibile (no refunds/chargebacks) anymore. See image on that website.

I looked at the image. I don't see anything that says that transactions aren't irreversible. Where does it say that?

Quote from: dolphin001 on March 27, 2014, 04:08:29 PM

Also are there any other disadvantages in electrum?

I'm not an expert with Electrum. Many people like it. Others prefer some of the other wallets. There are entire sub-forums here at bitcointalk.org to discuss each of the various alternative wallets. I suggest you have some conversations in those sub-forums with users of each wallet to determine what they do and don't like about the wallet they've chosen.
