Bitcoin Wallet Store Bitcoin Cash (BCH) & Bitcoin (BTC)

(newbie) Using multibit i got sent a fraction bitcoins through bit coin tip, but now it seems i cannot get back the wallet file. Is it possible using just the address to get the bitcoins back. (any help?)

I had succesffuly transfered to my new multibit wallet Addresss. Then when testing, through copy and paste the wallet file in multi bit. When I re-opened the file the address was gone.
I have tried:
-Resyncing the block chain
I did password protect the multibit file, but the new file which i opened from backup does not ask for a password.
Even the orginal file does not load to the orginal settings.

I currently have some Mastercoins associated with an address held in my Bitcoin-QT client. Can I import that wallet into electrum or multibit and still have control of the Mastercoins?

Hey I made a post on here earlier today and this is just an update on my situation. I sent bitcoin to my friend but little did I know he changed this bitcoin adress to remain untraced. So I basicly sent it to an old btc wallet that he no longer has access too. He does not know the seed to this wallet but I am wondering if I could recover the wallet with the btc I sent to it by using digital forensics? I'm sorry I know I sound very dumb I'm just very new to this and looking for any help I can get thank you :)

Multibit HD to Keepkey

Hello guys. I transferred my BTC/XBT from Multibit HD to Keepkey on August 2 2017, where have my BCC/BCH gone? I can not find them. Had the Bitcoins as MINE, not on a third party platform for a long time before 08/02/17.
$300 for the correct answer. x x

I just sent 4.0 BTC to an old Mt. Gox address using Multibit. FUCK

This is very sad indeed. I was trying to send money from my mycelium wallet to my multibit wallet. My multibit wallet was displaying a QR code but it was for a send address. Turns out this was an old Mt. Gox address.
Is there anything I can do. I'm fucked right.
Fuck. Me.
Please comfort me in my time of sadness.
Update @3:58AM: I've contacted Mark, [email protected], as well as placed an inquiry with TheDJFC, who famously did the same thing but with 200x as much and recovered the loss, has kindly offered his assistance. I will post updates as I am able.
Update @4:22: -----BEGIN BITCOIN SIGNED MESSAGE----- profbs -----BEGIN BITCOIN SIGNATURE----- Version: Bitcoin-qt (1.0) Address: 12ui22xrbid86SMM1jrjxZYp7Add4QZLJv

Update @6:26: Lawyer has agreed to begin the recovery process.
Update @ 11:47: We are attempting to help another redditor who has had the same problem. This is a strong community. I am pleased to see so much positivity in this thread and so many people who are both supportive and committed to doing the right thing.

MultiBit to fund development by charging users 1000 satoshis (0.5c) per transaction

MultiBit to fund development by charging users 1000 satoshis (0.5c) per transaction submitted by platypii to Bitcoin [link] [comments]

I am not technical. I need help recovering unconfirmed funds from an old MultiBitHD transaction. I will give you 20% of the transaction if your advice leads to successful recovery of these funds. Details in thread.

Final Update: A donation of 20% of the transaction mentioned above was made to the Electronic Frontier Foundation. Thank you all for the advice and your time!
I transferred .071xxxxx BTC several months ago to a wallet held locally in MultiBitHD and did not recheck the transaction. Apparently it did not go through all the way.
Here are three screenshots detailing the transaction.
Transaction number is as follows:
According to "Blockcypher", the transaction was successful however the funds are still inaccessible to me to transfer to something outside of MultibitHD, which is showing them as "Unconfirmed" as you can see in the pictures above.
Steps I've taken so far based on advice I've found online:
I have attempted a "Repair Wallet" in MultibitHD. This did not work.
I have attempted to rename the wallet directory and created a new one. This did not work.
Bottom Line At this point, I'm at the absolute top of my technical knowledge. My understanding is that the hold in funds might be due to a problem with the transaction fee. I have no idea....this is my hail mary pass. The point is I need one of you who is smarter than me at this stuff to help me clear this. I will give you exactly 20% of the funds recovered from this transaction if you can give me clear, step-by-step instructions as to how to recover these funds.
Additional Details
I am running a mac.
I have necessary passwords, seed words, and date stamp for this particular wallet.
As far as your payment goes, Unfortunately I can only guarantee this on an honor system basis. I am not an asshole. I pay my debts. I've spent all morning trying to solve this problem and I can find no clear answer written in a non technical language that I understand, so if you help me your efforts will be well worth the cost.
-PM's welcome. I don't care as long as I can get this done.

TIL why Newbies still download the Bitcoin-QT client!

Because we told them to. Newbies don't start with reddit or bitcoinforums (unless they are redditors, of course). They start with what looks like an authoritative source. (And journalists do the same.) Let's have a look. has a list of wallets and recommends two good options at the top, MultiBit or Schildbach, but if you take a look at the bottom, it prominently lists: Bitcoin-QT and Armory (which requires Bitcoin-QT/bitcoind). This is fine, I suppose, but it explains the popularity of Bitcoin-QT since most alternatives come with warnings.
weusecoins, a website that is prominently featured as a first stop for newbies, sends users dierectly to Bitcoin-QT, without any explanation or alternatives.
Bitcoin Wiki same same
This guarantees some bad user experience. Can we fix it? Who edits and

I found a Bitcoin on a wallet on an old laptop I was going to throw out. I'ts taking forever to synchronise as it was last used about 2 years ago and it keeps overheating and switching itself off. Is there a way of speeding up the synch?

Another MultiBit Bug - Cannot transfer more than 999.99 BTC at a time.

Tried to move 1400 BTC the other day out of my wallet (to get away from multibit) and almost had a heart attack when I was getting Java errors from trying to transfer my BTC out.
You can only transfer 999.99 out of the wallet at a time... seems they have never tested moving >= 1000 BTC out. Would be interesting to see if the problem also happens on deposit.
EDIT: Just letting everyone know that I've moved to Armory with paper backups - this first bug reported freaked me out. You could imagine how I helt as soon as I went to transfer it out and find that there was a java number error!!
EDIT2: I think this post also needs visibility:

Are there any wallets that have built in CoinJoin? Should we be demanding this?
Discussion between Andreas Ant and Adam Back on Bitcoin fungibility (1 hour mark).
I would love to see a wallet implement CoinJoin.
Ideally, mixing would be on by default, but I would settle for "checking a box".
Was DarkWallet an exit scam or is there an actual working version?

Major Flaw with Multibit - Have I completely lost my Bitcoins - Please Help !!

SORRY, I SHOULD HAVE SAID "POSSIBLE MAJOR FLAW WITH MULTIBIT" Hi, please help. I had 0.533 coins in my wallet and sent 0.10 over to Cryptsy Monday night. I have opened Multibit last night to see that my remaining balance has been sent to an unknown wallet. It seems Multiibit has created this change wallet but I have no idea how to get my change out of there and back into my own wallet? I can see the transactions on block chain and it says they are unspent but how do I retrieve them? There has been no new wallet created in my multibit folder and I'm desperate to get them back. Please help if you can. I have no idea where Multibit would have saved the private key for this wallet, I have searched through all my Multibit folders and cannot find anything? Thanks in advance

KeepKey Pin Not Working

My KeepKey pin recently stopped working. This seems to be an issue when I google it. I heard I can recover my wallet with Breadwallet or Mycelium.
I tried using my KeepKey recovery phrase with Breadwallet and Mycelium. The recovery phrase is verified, but both wallets show 0 bitcoin balance. I tried rescanning the network a few times too.
I also contacted KeepKey but they are really slow in responding. Anyone have the same issue or have any suggestions to recover my wallet?

Bitcoin is not the answer for micro transactions (AKA how do I rebroadcast an unconfirmed micro transaction)?

I was under the impression that Bitcoin would be the answer for sending micro payments over the Internet, but that is apparently not the case at all.
With a .0001 BTC required transaction fee for all transactions under .01 BTC, that amounts to a 6% transaction fee (at today's exchange rates) for a $1 USD transaction. And that equates to a 12% fee for a $.50 USD transaction. These fees are significantly higher than credit card fees, Paypal fees, Western Union fees, and even foreign exchange rate fees.
A few days ago, I didn't realize any of this information (i.e. the required fees), so I tried to send $1 worth of BTC to a friend WITHOUT a transaction fee to show him how "amazing" this new technology is. Turns out to be not very amazing at all, because the transaction never confirmed because of the lack of the transaction fee. Worst of all, there seems to be nothing I can do about it... I can't even add the 6% fee to it now, in order to get it confirmed! :(
I used the BitWallet app on iOS to send the transaction, and the hash of the transaction is: c238d939b330b682abe1c729300636600254c23c67e1eea4e8daa9abc26dd2c5
So now the transaction is in a permanent limbo state that can't be resolved, and I have effectively paid a 100% transaction fee because the money is in limbo. :(
Is there anything I can do to rebroadcast this transaction with the appropriate fee, so it actually confirms?

I think I just lost 90BTC! Are they stolen?? Help!!!

Here's my wallet:
It's a brain wallet with a pretty darn good passphrase
Why is my transfer grouped with another transfer of 87.999BTC?? I used a Xubuntu Live CD and generated the privkey from my passphrase using a downloaded html from I used MultiBit and exported my wallet to a file, then modified the file to contain my priv key, then I transferred 12BTC to my blockchain wallet. Then I deleted the wallet, closed MultiBit and shut down the PC. Are my bitcoins lost forever???
edit: still struggling. I've done a "cat /dev/sdb > usbstick.bin" and copied the casper-rw file directly. mounting the casper-rw file works and I browsed to ~/MultiBit. There's one wallet there that looks interesting, but I cannot read or copy it in any way...
$ ls ls: cannot access multibit-20130321171949.wallet: Input/output error log multibit.blockchain multibit-20130321171949.wallet multibit-20130331160220.wallet multibit.wallet
searching for org.bitcoin.production through the casper-rw gives me 3 hits.
I also extracted this from the casper-rw:,1 walletVersion,2 receive,1BndiDjH6eLsGajv5mzenNTx1z33hf9udT, property,walletDescription,Your%20wallet%20description property,walletFileLastModified,1363908467000 property,walletInfoFileLastModified,1363908467000 property,sendPerformPasteNow,false property,receiveLabel, property,walletBackupFile,%2Fhome%2Fxubuntu%2FMultiBit%2Fmultibit-20130321232754.wallet property,walletInfoFileSize,492 property,receiveAddress,1BndiDjH6eLsGajv5mzenNTx1z33hf9udT property,walletFileSize,104
edit2: when trying to read the wallet file from casper-rw, dmesg says: [ 7994.345782] EXT2-fs (loop1): error: ext2_lookup: deleted inode referenced: 64322
edit3: MultiBit is using bitcoinj, which stores the wallets in a protobuf format. I downloaded protobuf and the bitcoinj source, extracted the wallet.proto stucture and wrote a small C++ program that searches in the USB stick bin file for the string "\x0A\x16org.bitcoin.production", and tries to parse it as a protobuf wallet of size 8-50000 bytes. I found a couple of wallets, but only empty ones and my brainwallet. The structure with a header and reversed bytes that 4461462665 is refering to seems to conform with what I've read about how protobuf serializes data. I really think the wallet is lost. I'm going to quickly set up a sandbox that selected hackers can have a stab at. If anyone manages to recover the bitcoins, they are free to keep 30%.
edit4: TLDR; The story: I used a fresh MultiBit client, imported my brainwallet private key, made a 12btc transaction and then deleted the wallet. Turns out MultiBit picked up a 100BTC "input" and transferred the "change" (88btc) to the first key in my wallet (one generated by MultiBit before importing my own key). I have searched (hard!) for the key. I'm giving up, and will let the hackers of the internets take a stab.
edit5: I really think the bitcoins are lost. Looking at .wallet files from MultiBit, they all seem to store the private key in plain hex, prefixed with the string 1A 6E 08 01 12 20. I have searched for this string but all I could find was the wrong private key.

Is there a difference between wallets?

I want to get into Bitcoin, but I'm not sure on the specifics. Is there a difference between the wallets? Are there some that are better suited for certain transactions than others? Can I own multiple wallets for security purposes?

How should I keep my Bitcoin safe?

Hi, I need some technical help here. In a rare moment of lucidity I bought Bitcoin back in march 2013. I did what everyone recommended, I put a password on the wallet file and I made backups of my wallet file.
The problem is that naive me thought he would contribute to the network, by using Bitcoin QT. Today I have a file of 50 gigabyte on my computer and will have to download a few more gigabyte if I ever want to spend my bitcoin.
I'd rather not upload my wallet file to cause that whole process seems like a recipe for disaster. Is there some easy method to import my wallet file into a lightweight client that I can install on my computer, that doesn't start downloading the whole blockchain everytime I start it up?
