There is no way to bypass reindexing. It is a part of how Bitcoin Core works. You can move to another wallet, but the wallet files are not compatible so you will have to export the private keys and import them elsewhere.

So I have to wait until it finishes reindexing by slowing down my computer?

If you want to continue to use Bitcoin Core, then yes, you will have to wait for it to finish.

I want to move my wallet to Electrum, I'm tired of Bitcoin Core. It's too slow.
Is it possible to do that without waiting for the reindex to be finished?

Wouldn't have to reindex if you downloaded a copy of the blockchain from somewhere. Like, say, a remote server.

Not sure why you need to reindex in the first place, why didn't it just pick up block downloads where it left off?

How about Qt version 4.8.3? Is it possible to move a bitcoin address from Qt 4.8.3 to somewhere else?

Qt 4.8.3 is NOT A VERSION OF BITCOIN. That is the version of the GUI framework (Qt) of your version of Bitcoin Core. 4.8.3 hasn't been used in some time, so you are probably using Bitcoin Core 0.9.x or earlier.

The same process can be used. It hasn't changed in a long time.

The problem is I can't find the private keys on this 4.8.3 version of the bitcoin wallet.

Again, the wallet is not version 4.8.3. Look at Help > About Bitcoin Core and it will tell you what version of Bitcoin Core you are using. The Qt version doesn't matter.

You get your private keys using dumpprivkey. I described how to do that here: https://bitcointalksearch.org/topic/m.15015386. If you are getting an error, then please tell us what error you are getting.

Bitcoin version v0.8.1-beta; there is no Debug Window on help section of this client.

I still don't understand which address should I use. One that I've sent bitcoins? Received?
?¿

Any address that contains bitcoin and any address that you want to have in your new wallet.

Isn't there another way to just export the wallet.dat file and move it into another wallet without doing that dumpprivkey?

No there is not. The only software which is capable of importing the wallet.dat file is Bitcoin Core.

How do I generate that address for the dumpprivkey command?

That address is just any address that you have used that has Bitcoin that you want in Electrum. If you don't have any such addresses, then exporting the private keys is not necessary as you have not used any addresses.

Yes.

Start Bitcoin Core. Go to Help > Debug Window > Console. In the text box at the bottom type

Code:

dumpprivkey

Where

is the address which you want the private key of. The output should be in black and be a single string that starts with a 5, K, or L. This is your private key.

DO NOT SHARE YOUR PRIVATE KEY WITH ANYONE. ANYONE WHO HAS YOUR PRIVATE KEYS WILL BE ABLE TO SPEND YOUR BITCOIN.

Do that for all of your addresses.

Then start Electrum. You can either import your private keys or sweep them. Importing means you will still use the same addresses, sweeping will simply move all of the Bitcoin to an address in the Electrum wallet. I recommend you sweep.

To sweep, create a new normal Electrum wallet. Make sure you record the wallet seed. Then when the wallet is made, go to Wallet > Private Keys > Sweep. Enter all of your private keys, one on each line, and the wallet will automatically sweep the Bitcoin into your wallet.

To import the private keys, go to create a new wallet but instead choose "restore a wallet or import keys". Click next. In the box, enter your private keys, one on each line. Follow the rest of the instructions and you will have created a new Electrum wallet with your keys imported.
