Have you recovered your wallet yet? If not, simply follow the following tips:

1. Backup/Copy your wallet.dat file to the desktop which is in your bitcoin folder.
2. Delete the Bitcoin Core software.
3. Re-install the bitcoin core software and place the old wallet.dat file in the new bitcoin core software folder.
4. Export your private key from the console of bitcoin core software.
5. Simply create new account at blockchain.info and import your private key there to instantly have your bitcoins.

If you follow the instructions given above, you won't have to wait for the software to sync and get all those GB's of data from the internet... It will be pretty simple to have your online bitcoin wallet at blockchain.

i was only able to recover a fraction of my total btc i should have in my wallet.

I dumped all the private keys from all my received address' and sweeped them in Electrum

is it possible that more transactions will appear when the blockchain finishing syncing?

i have 3.3BTC in pending amount (correct perceived amount)

will I have to wait for the sync to be complete to know if my BTC is actually there?

You don't need to wait for any kind of sync in Electrum. And you probably forgot change addresses (shorena has that covered):

If you are exporting keys, just export all keys. Same steps as here[1], skip 6 since you have no password[2] and replace 7 with ( dumpwallet mykeys.txt )[3]. The file will be unencrypted and contain a list of all (including change) your private keys. Either import them all into a different wallet or swipe them one by one until you have all your coins back.

[2] seriously? Change that with your new wallet.

Yes. You always need to finish syncing to actually have the correct amount be there. Otherwise the wallet doesn't actually know about the transaction or whether it is confirmed.

when trying to sweep i am getting

No inputs found. (Note that inputs need to be confirmed)


You seem to be sweeping from addresses that have no coins. Check your addresses on Blockchain.info or Blockr.io and sweep only from those who still have coins.

7. Dump your keys. Do dumpprivkey for each Bitcoin address you want to dump your keys from (copy your addresses and place them after dumpprivkey, without the brackets too)


Do i get these address' from EACH old transaction in my transaction section on the btc core?

You get them from your receiving addresses tab

After step 6 on the debug window I get


18:08:32

Error: running with an unencrypted wallet, but walletpassphrase was called. (code -15)




You can skip the passphrase step, then. It seems your wallet had no password.

Sorry as you can See I'm new to BTC.


Step by step:

What is the fastest way for me to take my wallet.dat file and access my btc?

1. Install Electrum
2. Create a new wallet
3. Backup the seed of your new wallet to a safe place (ex: paper)
4. After creating a new wallet, go to Wallet - Private Keys - Sweep, leave this open
5. On Bitcoin Core, go to Help - Debug Window - Console
6. write walletpassphrase 800 to unlock your wallet (in place of write your wallet password, without the brackets)
7. Dump your keys. Do dumpprivkey for each Bitcoin address you want to dump your keys from (copy your addresses and place them after dumpprivkey, without the brackets too)
8. Insert these private keys on that Sweep menu in Electrum
9. Coins will be sent to an address on your Electrum wallet. You can now close Bitcoin Core and use your coins.

Will this work for all other coins, which are inferior to Electrum?

I referred Electrum just because it is a client I am familiar with... Not sure I understood your post, what do you mean by inferior?

which client should i use that will not take up so much space?

Will I be able to just import my wallet.dat file?

Electrum and MultiBit are fine. No, you can't import the wallet.dat on other clients

- snip -

You'll probably only need to backup your wallet.dat, delete the files and restart Bitcoin Core, no reinstall should be needed. It will then start resyncing.

I guess he would only get the same problem of his disk filling up again?

See OP:

How do I re-install the core without losing my btc?

The user asked how to get Bitcoin Core running again (and says he is a noob), so one thing at a time. And yes, around 70GB are currently needed for Core, the user is probably already aware of that.



Do

so my process should be:

go to
 ~/Library/Application Support/Bitcoin/

back up wallet.dat on my desktop. delete the rest of the files, then download and reinstall core?

Replace new wallet.dat with old and reopen the core?

Do I need to backup any other files?

You'll probably only need to backup your wallet.dat, delete the files and restart Bitcoin Core, no reinstall should be needed. It will then start resyncing.

it's now re-synicing with the network.

Is there a faster way for me to access my btc using my wallet.dat?

Will this give me the same problem if filling up my drive?



Yes, there is. You can dump your private keys and use them in another client. Yes, the blockchain takes up around 70GB, so be sure to have enough space for it.
