[RESOLVED] How to send Bitcoins with MultiBit?

[nicofan]

Hello

I have a problem for which I can't seem to figure the solution. I have the Bitcoin Client "MultiBit" Version 0.5.9 (most up to date i think).

I transfered bitcoins from mtgox to my wallet. no problem.

now I have 0.5762188 BTC in my wallet. I tried to send these (ALL OF THEM) to another wallet. I quickly noticed that there is a fee (or call it a fine) I have to pay. If I go to settings it says "Fee: 5 BTC". I changed it to 0.0001 which I found out is the lowest. When I go back to the Send Coins tab it changes the fee to 1 BTC. Wow, cool.

Ok, when I try to send the Bitcoins it tells me something like. "I do not have enough funds to make the transaction. Transaction fee is 1 BTC".

Even if I try to send 0.5754 of my 0.5762188 it still does not work although there would be 0.0008 to cover the fee.

Can anybody give me a hint what I am doing wrong?

thanks

(My MultiBit is in german, so I can't post the exact Error in english"

Try getting out your wallet.dat file
Uninstall the client, then install it again.
Access your wallet and check if it gives you the same error, if so,
Try to access your wallet using a browser-client like www.blockchain.info
You could gain access to your wallet on Blockchain.info by importing your wallet.dat
After you access your wallet on BlockChain , try to make the transaction.

It isn't an error, it is cause your wallet probably has a lot of "dust" (which is really small amounts) so to protect the network against dust/spam and a lot of small inputs, the fee is huge.

This shouldn't be true.  Look at what the OP wrote:

now I have 0.5762188 BTC in my wallet. I tried to send these (ALL OF THEM) to another wallet.

It sounds like that 0.5762188 BTC is a single transaction from MtGox in a single output.

nicofan, you can confirm this for us if you post the bitcoin address from your wallet here.  We should be able to look in the blockchain and confirm that the 0.5762188 BTC is a single output and not made up of many really small amounts.

This sounds like a bug in the MultiBit software.  If the amount really is a single output, then the fee requirement shouldn't be more than 0.0005 BTC.  Once you confirm for us that the 0.5762188 BTC is a single transaction with a single output, I'll cross post this to the MultiBit sub-forum so you can get an answer as to how to fix it.

OP has to confirm that, but I thought maybe many different transactions because Mt Gox has deals with mining pool so they can dust the blockchain and not have to pay large fees.

Agreed.  It's difficult to make an educated guess as to the cause of the symptoms being described without additional information.

nicofan,  Please provide the bitcoin address (or addresses) from your MultiBit wallet so we can confirm that it isn't filled with hundreds of tiny outputs from MtGox or from activities such as SatoshiDice or "free bitcoins" websites.

[nicofan]

hello

thanks for the answers.

the wallet address is: 151Z8BwDCJnx1DKw1fDAu8tgjG6gTp5xf8

yes, it was a single transaction from mtgox to my wallet (yesterday). I have installed the MultiBit client yesterday.

[DannyHamilton]

Great, so we can now see here in this transaction:

https://blockchain.info/tx/61303c25d01784857e6e2de95817e735cfc9c0f693e1506fb0e13bd418b1b524

that MtGox sent 0.5762188 BTC.

Oh, wait, I just remembered reading about someone else having this issue recently.  I'm almost certain this IS a bug in the version of MultiBit that you are running.  I'm not sure, but there may be a patch available.  I'll look and see if I can find the discussion, and if so I'll post a link here.

The issue was that a recent version of MultiBit wasn't properly handling situations where the comma and the decimal point aren't used they way they are in the United States.  I suspect that in German, a comma is used instead of a decimal point, right?  Hopefully, I'll be back shortly with a link for you.

[DannyHamilton]

Apparently no patch yet.  According to the following discussion the only solution at the moment is to install version 0.4.22:

I have 10.8 BTC on my MultiBit wallet. I want to transfer my BTC to my account at btc-e.com market. But MultiBit wants me to pay comisson 1 BTC for transaction. Even if I try to transfer 0.1 BTC.

- snip -

the issue solved by downgrade to version 0.4.22! 0.4.23 must have been buggy(((
Thanks fsb4000!

This was a bug to do with parsing of the transaction fee when you have a locale that uses a ',' as the decimal separator.
It is fixed in release 0.5.9 (https://multibit.org/releases.html).

You can just set the transaction fee in the Preferences tab. Press 'Apply changes' to save the new amount.

- snip -

Still not fixed in 0.5.9 version.

It sounds like you either need to change your locale to somewhere that uses a '.' as the decimal separator, or you need to install 0.4.22

[nicofan]

ok, I'll try to downgrade to 0.4.22.

What do I have to backup before I uninstall MultiBit?

In the original folder where I saved my wallet, are the following files:

walletname.info
walletname-20130430233733.key
walletname-20130501195242.wallet
walletname-20130501195442.info
walletname-20130501195442.wallet
walletname-20130501195442-20130501202028.wallet

Do I have to keep all these files and use them with version 0.4.22?

I also have to say that I only have ONE wallet, why are there 3 of them. Which wallet should I open with 0.4.22?

This is so confusing.

I'm not a MultiBit expert, but I suspect that those aditional ".wallet" files are just backup copies.

I suspect that you can install the 0.4.22 upgrade and your wallet will be fine, but I'd create a backup copy off the computer (perhaps to a USB drive) just in case of disaster.  Perhaps backup all the files, and then figure out which of them you actually need to recover if the upgrade doesn't behave as expected.

Another option would be to find out how to export the private key for the address before you do the "downgrade".  You could write (or print) that private key to a piece of paper.  As long as you have the correct private key, you'll be able to regain control of the bitcoins even if MultiBit becomes completely unusable for you.  That private key can be imported into another wallet, or swept back to MtGox if necessary.

[nicofan]

oh no.

what exactly is this "private key" ? is it the file "walletname-20130430233733.key"?

Because I uninstalled version 0.5 and installed 0.4.22 and now I get this:

"com.google.protobuf.InvalidProtocolBufferException Message missing required fields: key[0].type"

I can't open any of the 3 wallets listed above, I always get this error. When I try to import the key it says "no wallet selected". I can't open the wallets because it doesn't find the key, and I can't open the key as long as I can't open/select a wallet. nice.

can somebody tell me which one of these wallets is not completely retarded?

http://bitcoin.org/en/choose-your-wallet

the first one Bitcoin-Qt took up around 20GB of HD space. Before it even completed downloading more, I deleted it (that was the day before yesterday). The second one MultiBit can't send money. Is there a recommended one which you people use without problems?

Thanks.

[DannyHamilton]

I'll cross post this thread to the MultiBit forum for you.  Hopefully someone with some expertise there can help you recover your MultiBit wallet.  If not, hopefully they can help you get your private key from the files you have so that you can import it elsewhere.

thanks for mentioning my post in the section where the multibit professionals are.

I went ahead and installed version 0.5.9 again on the same computer but in a different location. I now have both versions installed. On version 0.5.9 I was able to open the wallet (it somehow imported the key itself). I can see the bitcoins there.

In this post: https://bitcointalk.org/index.php?topic=170716.0        // in post number #7 they say:


"Some changes from testing 0.5.9:

+ The key.type persistence error mentioned in the previous post is legitimate (there is now a new category of key.type for encrypted keys that was not in 0.5.8. It prevents earlier versions of MultiBit reading encrypted wallets so is a good thing)."

This tells me I can't use any other version than 0.5.9. I'll wait and hope some multibit pro can help me out

[nicofan]

IT WORKED !

I was finally able to send the bitcoins. The solution to the problem was quite simple.

My ballance was not 0.5761188, it was 0,5761188. MultiBit works only if you put a COMMA between the numbers. In Europe (at least in Switzerland) we have a dot "." between numbers, not commas.

It finally accepted 0,0001 BTC as fee (NOT 0.0001 BTC).

Thead can be marked as solved. special thanks to DannyHamilton.

Glad to hear you got it resolved.  You can update the Subject line yourself and add [RESOLVED] so others know.  You can also "lock" the thread at the bottom so it doesn't get filled with useless unnecessary drivel from other newbies.
