Topic: URGENT QUESTION : How to send from 1 address? (Read 1488 times)

finished downloading, and now?

update : importing blocks from disk
but seems to still take a few days

so I'll continue in blockchain
If i understand it well, if I can get 100 transactions of 1 btc to 1 address that 1 address can spend 100 times 1 btc immediately (in separate transactions)
then i need a place who can do that, i'm thinking about primedice withdraw small amount a lot of times? (a site with instant withdrawals and small/no fees)

ok, tx for all your help but still don't get it, that post seems to refer to pay more addresses from 1 address? 

You need to make 4 clicks in the GUI I believe to do that.
But if you need to do 100 transactions, it is better to use sendfrom command (check Stinky_Pete's post above for details).

ok i got it, tx for the explanation
now downloading the torrent but it will take 86 weeks  
really slow internet here, yes...
I can activate my wifi hotspot on my phone but then I think I'll run out of data...

maybe i'll go somwehre else to download it
to be sure: with bitcoin qt
I can just say:
I want this address A1 to send to address B2, A2 to B2, A3 to B3 ... (100 transactions) and repeating this all the time with only 1 click?
So i really need 100 separate transactions every click with a fee not bigger than 0.01 mbtc per transaction (1 mbtc per click)

The initical sync shouldn't need a week, unless you have a rather limited bandwidth. In my case, it took me less than 24 hours. Use the bootstrap torrent to make the blockchain download faster. https://bitcoin.org/bin/blockchain/bootstrap.dat.torrent

Because bitcoin transaction spends unspent output. You have to spend the whole unspent output but not part of it. In your case, you didn't just spend 1 bitcoin out of the 10 bitcoin in your wallet. Instead, you spent the whole 10 bitcoin and then received 9 bitcoin back as change.

so then i just need to wait a week for synchronization? no other faster way?
i still dont get why when i have 10 btc in my wallet, i spend 1 btc why i can't spend the other 9 btc :s

Yup Bitcoin Core can do that. You just need to enable coin control and you can specify which unspent output you want to use in your transaction.

ok, blockchain just made me lose more than 0.2 btc in total since they transferred from more addresses while i didnt know so i didnt get paid out   I hate blockchain.info, any address means any mix of addresses, there site is far from clear and full of lies 

so now i know for sure that i need to transfer from 100 btc addresses each of them to 1 specific btc address, 1 transaction for each btc address (really necessary) every 10 minutes. (fee of 0.01 mbtc for every transaction is fine and is always confirmed in the next block so i dont want to pay more). How can i do this? Is it possible with bitcoin core?

it's still loading for more than a day i think
can i do it with blockchain like on the link?
i tried it with the addresses on that link and it worked but not anymore now with other addresses

UPDATE : I locked myself out of my blockchainwallet with 0.7 btc in it, don't have the right ip? I hope my ip changes soon again to the old one

If you have access to a qt-wallet, you can do it from the console


sendmany "fromaccount" {"address":amount,...} ( minconf "comment" )

Send multiple times. Amounts are double-precision floating point numbers.
Requires wallet passphrase to be set with walletpassphrase call.

Arguments:
1. "fromaccount" (string, required) The account to send the funds from, can be "" for the default account
2. "amounts" (string, required) A json object with addresses and amounts
{
"address":amount (numeric) The bitcoin address is the key, the numeric amount in btc is the value
,...
}
3. minconf (numeric, optional, default=1) Only use the balance confirmed at least this many times.
4. "comment" (string, optional) A comment

Result:
"transactionid" (string) The transaction id for the send. Only 1 transaction is created regardless of
the number of addresses.

Examples:

Send two amounts to two different addresses:
> bitcoin-cli sendmany "tabby" "{\"1D1ZrZNe3JUo7ZycKEYQQiQAWd9y54F4XZ\":0.01,\"1353tsE8YMTA4EuV7dgUXGjNFf9KpVvKHz\":0.02}"

Send two amounts to two different addresses setting the confirmation and comment:
> bitcoin-cli sendmany "tabby" "{\"1D1ZrZNe3JUo7ZycKEYQQiQAWd9y54F4XZ\":0.01,\"1353tsE8YMTA4EuV7dgUXGjNFf9KpVvKHz\":0.02}" 6 "testing"

As a json rpc call
> curl --user myusername --data-binary '{"jsonrpc": "1.0", "id":"curltest", "method": "sendmany", "params": ["tabby", "{\"1D1ZrZNe3JUo7ZycKEYQQiQAWd9y54F4XZ\":0.01,\"1353tsE8YMTA4EuV7dgUXGjNFf9KpVvKHz\":0.02}", 6, "testing"] }' -H 'content-type: text/plain;' http://127.0.0.1:8332/
(code -1)

That is a very bad design.  Personally, I wouldn't trust a service that implements such a rule.  Clearly they haven't taken the time to properly understand bitcoin, or to put together a well designed website.  I'd take my business elsewhere.


Bitcoin doesn't send "from an address".  It spends unspent outputs.  Regardless, yes, you can have a single transaction with multiple outputs.  I'm not sure what the limit is on outputs, but I'm pretty sure 100 would be possible.  Some wallets might limit how many outputs they will allow you to have in a transaction.  If the wallet you are using won't allow 100 outputs, then you might want to look into some other wallet.

Many wallets allow you to send different amounts to different addresses all in the same transaction. Bitcoin Core has the "sendmany" command, for example. I use it to fund physical bitcoins and paper wallets (50 at a time). I don't know if its GUI lets you.

i'm wondering if it is possible with blockchain to send an amount from 1 address to 100 different addresses?
i found it here
https://blockchain.info/nl/api/blockchain_wallet_api

but how do i do that?

takes a long time to download 

ok, tx for info, ill try it out
and I need it because funds will be send back to the same (and only 1) address as i used for the deposit. that's all
is it also possible to send from 1 address eg 1 bitcoin to 100 other addresses each?

You need a wallet that provides coin control.  The most recent versions of Bitcoin Core provide coin control.


If you want a low fee, then you probably need to change how you are handling the situation.  Why would you want to send many small payments very quickly in separate transactions?  It would be cheaper and faster to combine all the outputs into a single transaction,


No.  As long as the address has multiple unspent outputs, you can create a separate transaction for each unspent output.  I don't understand why you would want to do this though.  I suspect that you don't understand how bitcoin works, and therefore are trying to do something that you don't need to do.


Just a disadvantage from some wallets.




That sounds like a very silly thing to do.


Use a wallet with coin control.

Or send multiple outputs from a single transaction.

ok, it seems to work fine, only a lot of work on blockchain giving in the amount, clicking a lot to confirm, any faster options?
need to make a huge amount of bets

in blockchain any address means from 1 of your addresses or also possible a combination (that is what i don't want)
otherwise ill just make 100 wallets, put some btc on it and go

yes, but 0.01 is enough to be included in a block
so then i need to open a lot of wallets on my own?
So it's impossible to do more than 1 transaction from 1 address within 10 minutes? A serious disadvantage for bitcoin then...

Every bitcoin client will force you to wait for 1 confirmation because you need at least 1 confirmation to be able to spend the output.

You can't have low fees because you are spamming the bitcoin network when you send many little payments, the fee will let miners accept it into a block.
